How To Improve CNC Programming Workflow With CAD/CAM

The use and application of CAD/CAM technology into your CNC machining workflow-process can make the differences in producing parts perfectly and efficiently while maintaining and enhancing the high level of quality that you need in each step of the process. 

CAD Files & Their Compatibility

CAD workflow begins with how you can acquire and manage your part model. With today’s developments in hardware design software technology, most CNC manufacturing businesses start with a 3D model of a part either designed by you in your CAD software from a print or provided by a client. AutoCAD, Solid Works, Pro Engineer and SpaceClaim are examples of quality Design products that provide simple, yet highly advanced design and novel solutions in the world today. These products are nowadays more and more affordable and can even allow groups of designers to collaborate on assembly projects from different locations, solve geometry problems, repair bad geometry easily and just anything else can be imagined within the scope of design and innovation. Therefore it’s essential that a CAD/CAM system offers the ability to import or open CAD design files.

Using a CAD design product that offers CAM plug-ins will accelerate workflow efficiency such as SolidWorks and the BobCAM for SolidWorks Gold Partner CAM product. This means that designed part files do not have to be transferred into another CAM product, reducing file, surface and geometry issues and bringing the design to machining process.

 CAM Job Management

Once the part file is prepared for a move into the tool path and programming stage you will see that most CAM (Computer Aided Manufacturing) software products provide a standard “Job Tree” method of organizing machining strategies into a productive workflow such that tools can be added, tool path strategies can be used and a program can be created in its proper sequence.
You need to check with software provider for the library of post configuration files, mainly the one for your specific machine tool. While this is one of the biggest topics of CAD/CAM software and why CAD/CAM even exists, Workflow efficiency can be achieved just by having the software provider assist you in the designing or modification of posts. A correct post processor eliminates the need for you to have to hand edit code. Thus helping you to spend your time focusing on the machining side of it all.

 Toolpath & Machining Strategies

The next stage in the process of using CAD/CAM software involves the designing of Toolpath (cutter-path) which is the actual path that the cutting tool takes to machine the part. A CAM Tree-Job Manager will help you keep each machining operation organized and properly sequenced such that the g-code program produces the best possible cycle time for the job. 2, 3, 4 & 5 axis tool paths are all developed to produce efficient roughing and finishing cycles.

New users design programs in a fraction of time over tool path creation without using wizards and secondly, nothing is forgotten or left behind in making tool path that is accurate and properly calculated based off of the tools you setup for the job. Toolpath Wizards start by permitting you to choose the areas of the part to apply a specified toolpath (planar, spiral, z-level etc) within a boundary or an entire part, set clearances and height of rapid moves for the tool.

Then you can select the type of cutting pattern (zig-zag or single direction cutting), cutting direction (climb or conventional), roughing parameters, custom tolerance and cut-depth options, lead-in and out options, toolpath linking options (how you want to connect one path to another) and other custom machine options. When finished you will automatically generate the toolpath so you can visually see it.

Developments in workflow efficiency can also be achieved by using High Speed toolpaths. As CAD/CAM providers continue to develop their technology you could see high speed toolpaths available for more complex 3 Axis machining such as the advanced 2 & 3 Axis high speed Adaptive Roughing strategy that BobCAD-CAM software makes use of.

Simulation & The G-Code Program

The final stage in the CAD/CAM programming phase is toolpath simulation & designing of an NC Program file that can be sent to the machine tool. The simulation process allows the programmer to visually see the process and catch any errors within the program, gouges or collisions as an error detection stage.

Typically a number-color system is used to visually detect deviation areas, tools and machining operations. Advanced Machine Simulation helps you to use your machines Kinematics to simulate the actual machines motion as well as the tool path operations. Without a g-code program CAD/CAM is incomplete. This is a crucial stage of the process due to potential loss of valuable time due to hand editing g-code programs. 

Enhancing Efficiency & Beyond

These are general stages of CAD/CAM CNC programming process along with set examples of how one can improve the efficiency of a programming workflow by using it. While it is quite easy to say that CAD/CAM software must be easy to use, what is equally important is availability of training. Does the software come with training? If it does, then what forms is it available in? Are there training videos allow you to learn on your own time? The more options available, the better the ability to achieve operator certification as a professional.

We conclude the discussion here and hope that this blog piece has enlightened you on the efficiency of CAD/CAM Software for CNC machining.

Top Autocad Interview Questions And Answers

Interviews and associated blues makes matter tough and tensed. You might read the book in a year, but it’s not that possible to cover every topic just before every interviews. You need some last minute notes. Here we write for you some essential Autocad interviews questions and answers that could be of your help before facing interviews.

Define Autocad

Autocad is a software program that designs and shape 2-D and 3-D images.  It provides the tools a detail design of how the product could be done. It also gives the choice to create detailed design layout, which can be automatically drawn.

Uses of Autocad

Autocad is used by professionals to look into the imaginary view of the product on a computer system. In Autocad, the drafter can make the changes in the product before it gets finalized for design. It also provides the freedom for the designer to apply their various ideas and represent a model to their clients.

What are the fields maximum usage of Autocad can be seen?

Autocad is used by engineers, architects and builders for developing their layouts for buildings.

What file format is used in design?

The .dwg file format is used for design, it is an interchangeable format.  The interchangeable file format has the extension as DXF and operates data operability. It gives different languages which can be used as required.

How to create a user interface in Autocad?

User interface can be developed by using command prompts to draw the plots and dialog boxes. The dialog boxes could be displayed by the use of PLOT command and the external database commands. The user interface creation also requires the command line to display the entire file so that it could be edited or customized easily.

Mention the function of vertical integration

To improve the architectural designing of 3D object, Autocad uses this program. The 3D objects include walls and other things that are associated with the data having information and even simple objects like lines and circles. The data can be modified as per further requirement.

How is variant used in Autocad?

Variants are used to help in creation, visualisation and to render the 3D models that include 3D printing as well.  Variants help you to use the functionality of different application as per the requirement.

What are the benefits Autocad?

Autocad replaced the conventional method of drafting and designing which was done by pencil, drafting boards, triangles and compass with only a set of a computer program.  The benefits are many :

  • Time saving and helps to enhance productivity
  • Can streamline your design and workflow of your documentation
  • Physical ‘3D’ prototype can be fast created
  • 3D models can be directly imported into Autocad by the help of application like SolidWorks

How to draw a line more than once and save it automatically?

When you have to draw a new line, the system opens up a new file in a new session to write the file. Autocad saves multiple drawing for each session. The files are then saved by using the file extension .dwg and can be modified later by using the browser.

How to enable drag and drop feature in Autocad?

Autocad feature “NOUN” and “VERB” in a dialog box helps you with drag and drop.  It helps the object to move from one place to another.  Similarly, the remove or edit function can be done by the use of “MOVE and ERASE”.

Name the features corrected by Autocad?

Autocad detects the problem and correct it by removing the problem with the drawing parts.  With the option of adding additional vertices, it also adds vertices to the poly-lines. The error can be edited by finding out the exact location of the poly-line with zero vertices.  The object can be later deleted or removed when there is no use of it in the system.

How to set up a default drawing directory?

The applications, which are to be used, are highlighted, and by the drag and drop features those application will be placed in a default directory. Then select the properties for the application from the main menu and dialog boxes that gets displayed on the front.

How you can copy a closed drawing?

This can be done by the designer center in the Autocad toolbar.  Use the tree view option to see the copy of closed drawing and if any modification required, it can be done by using graphical interface.

How to hide specific layers when plotting in Autocad?

There are various options like turning off the layers for plotting , to freeze the layers and turn off. Turning off will make the layers visible on screen but disable printing option. The layers which are turned off will hide the layers and also will not be seen on screen.

How to copy dimension styles from one drawing to another in Autocad?

To copy dimension styles you need to set up the particular dimension style and for that a new document has to be created. After that, this document will be saved as a drawing template. A new reference is then created by a new drawing template document and it will show all the options like layer style, units and blocks.

Drawings can be done by looking at the present drawing and dimension style will be same as the original picture. So with the help of the design center, Autocad tools helps to copy the dimension styles from one drawing to another.

We conclude now.There are a few more important questions and answers related to the subject we discussed today. We shall cover them in our following blog. So keep a watch into this space for our upcoming blogs.

Advantages and Disadvantages Of Prototype

So what is a rapid prototype? A rapid prototype is a process where a working model is designed in order to do the testing of various product features like ideas, design, features, performance , functionality and output. This process of development of working model is quite fast. The user could give an early review or response regarding the prototype. Rapid prototyping is, basically, an essential and significant part of the system designing process and it is thought to decrease the project cost and risk.

A Rapid prototype which is developed by the method of rapid prototyping is based on the performance of earlier designs. So, it is possible to correct the defects or problems in the design by taking right measures. The product can be produced if the prototype meets the needs of all designing objectives after sufficient refinement. There are benefits of advantages of rapid prototyping.

rapid prototyping

Benefits:

  • Rapid Prototyping can give with concept proof that would be needed for attracting funds.
  • The Prototype hints the user about the final product look .
  • It can increase early visibility.
  • Easy to find design flaws in the early stages of developmental.
  • Active participation among the users and producer is encouraged.
  • It is cost effective,as development cost reduces.
  • Any deficiency in the earlier prototypes can be detected and rectified in time.
  • There is better communication between the user and designer.
  • The high-quality product is delivered.
  • Rapid prototyping helps development time and costs.

Drawbacks:

  • It fails in exact replication of the real product or system.
  • Some important developmental steps might get omitted to get a quick and cheap working model. This turns out to be one of the greatest disadvantages of rapid prototyping.
  • Another disadvantage is that many problems are overlooked resulting in endless corrections and revisions.
  • Unsuitable for large sized applications.
  • Compared to user’s high expectations, the prototype’s performance and the designer are unable to deliver these.
  • The producer may produce an inadequate system that is unable to meet the overall demands of the organization.
  • Over involvement of user might hamper optimization of the program.

Turbo-Charger

Do you know that the turbocharger was originally called a turbo supercharger as it is a type of supercharger. Hence the name was shortened due to convenience.

The purpose of a turbocharger is to constrict the oxygen entering a car’s engine and thus increases the amount of oxygen that enters and hence increases the power output. The turbocharger is powered by the car’s own exhaust gases. In simple words, a turbocharger renews a by-product of the engine that would be actually useless and utilizes it to enhance the car’s horsepower.

Did you hear about aspirated cars? Yes! The cars without a turbocharger or supercharger are called aspirated cars. The aspirated cars take in the air into the engine via an air filter; the air then passes via a meter, which monitors and regulates the amount of air that enters the system. The air is finally delivered to the engine’s combustion chambers, along with a controlled quantity of fuel from the fuel injectors or carburetor.

turbo charger

In a turbocharged engine, his air is pressed such that more oxygen will fit in the combustion chamber, thus increasing the combustion power of the engine. The turbocharger has two main parts: the compressor, which compresses the air in the intake; and the turbine, which draws the exhaust gases and uses them to power the compressor. Another term used commonly in relation to turbochargers is a boost, which refers to the quantity of pressure the air in the intake is subjected to; in simple words, the more the air is compressed, the higher is the boost.

The increase in power is a benefit to the car and likely a source of enjoyment for the driver. But like many things, a turbocharger also has its drawbacks. A turbocharged engine should have a lower compression ratio than an aspirated engine. Owing to this, one simply can’t put a turbocharger on an engine that was intended for normal aspiration without undermining the life and performance of the engine. Moreover, a lower compression ratio means that the engine will run with less efficiency at low power.

Turbo

Another major disadvantage of a turbocharger is turbo lag. As a turbocharger runs on exhaust gases, the turbine needs a build-up of exhaust before it can power the compressor; which means that the engine must pick up speed before the turbocharger can start. Even, the drawn air grows hotter as it is compressed, lessening its density, and hence its efficiency in the combustion chamber .

Introduction To Additive Fabrication

What is an additive fabrication? Well, this refers to a type of manufacturing processes, where a part is built by adding layers of material upon one another. These processes are different from consolidation processes or subtractive processes.

Subtractive processes like milling, turning, or drilling, use carefully planned tool movements to cut material from a workpiece to form the desired part. Consolidation processes, such as casting or molding, use customized tooling to solidify material into the desired shape. Whereas additive processes do not need custom or planned tooling.

The part is constructed directly from a digital 3-D model created through CAD software. The 3-D CAD model is transformed into many thin layers and the manufacturing machine uses this geometric data to build each layer sequentially until the part is completed. Owing to this approach, additive fabrication is also referred as layered manufacturing, direct digital manufacturing, or solid freeform fabrication.

Additive

Several advantages of Additive fabrication:

  • Speed :These rapid processes have short building times. Since no custom tooling should be developed, the time in receiving parts is greatly lessened.
  • Part complexity: Since no tooling is required, complicated surfaces and internal features can be directly created when building the part. Moreover, the complexity of a part has little impact on build times, as opposed to other making processes.
  • Material types : These processes are able to produce parts in metals, plastics, ceramics, composites and even paper with raw materials similar to wood. Moreover, some processes can build parts from multiple materials and distribute the material according to the location in the part.
  • Low-volume production : Other traditional processes are not very cost effective for low-volume productions because of very high initial costs. This process needs minimal setup and builds apart from the CAD model, permitting for low per-part costs for low-volume productions.

With all of these benefits, additive fabrication process can’t replace traditional manufacturing processes. Processes such as molding, machining and casting are still preferable with specific instances.

Applications:

This process initially produced parts with few applications owing to limited material options and mechanical characteristics. But improvements in the processing technologies and material types have expanded the possibilities for these layered parts. Now, this process is used in the variety of industries, including the aerospace,consumer product, architectural, automotive,military industries and medical products. The part application in these industries is quite vast. For instance, some parts are aesthetic such as sculptures, jewelry or 3D architectural models. Others are customized to meet the user’s personal requirements, like specially fitted sports equipment, prosthetic devices or dental implants. The following three categories are often used to explain the different application of additive fabrication and may be applied to all of the above industries.

  • Rapid prototyping for visualization, form/fit testing, and functional testing
  • Rapid tooling – Using additive processes molds and dies are fabricated
  • Rapid yield – Medium-to-high volume production runs of end-use parts

Dual Fuel System

This engine that runs on hydrogen, has the advantage of the characteristics of Mazda’s rotary engine yet gives a natural driving feeling like internal combustion engines. It is also eco-friendly with zero CO2 emissions.

Moreover, the hydrogen engine guarantees performance and reliability similar to that of a gasoline engine. Since the gasoline version needs only a few changes in design to permit it to operate on hydrogen, hydrogen-fueled rotary engine vehicles can be obtained at low cost. Moreover, because the dual-fuel system permits the engine to run on both hydrogen and gasoline, it is possible for long-distance journeys and trips to areas with no hydrogen fuel supply.

The RENESIS hydrogen rotary engine uses direct injection, with electronically-regulated hydrogen gas injectors. This system takes in air from a side port and injects hydrogen into the input chamber with an electronically-controlled hydrogen gas injector installed on the top of the rotor housing.

DualFuelSystem

In the application of hydrogen internal combustion engines, escaping of so-called backfiring is a major issue. Backfiring is the ignition due to the fuel coming in contact with hot engine parts during the intake process. In reciprocal engines, the input, combustion and exhaust processes take place in the same location—within the cylinders. As a result, the ignition plugs and exhaust valves reach a high temperature due to the burning and the input process becomes prone to backfiring.

In contrast, the RE structure has no intake and exhaust valves, and the low-temperature chamber and high-temperature burning chamber are separated. This supports good combustion and helps prevent backfiring.

Further, the REhelps mixing of hydrogen and air since the flow of the air and fuel mixture is stronger and the duration of the intake process is longer than in reciprocal engines.

Aiming to achieve a high output in hydrogen fuel mode, a direct injection system is applied by configuring an electronically-controlled hydrogen gas injector on the top of the rotor housing. By structure, the RE has freedom of injector layout, so it is well suited to direct injection.

Moreover, a gas injector for premixing is configured on the intake pipe that enables the combined usage of direct injection and premixing, depending on the driving conditions. This yields optimal hydrogen combustion.

Lean burn and exhaust gas recirculation are adopted to reduce nitrogen oxide (NOx) emissions. NOx is mainly reduced by lean burn at low engine speeds, and by EGR and a three-way catalyst at high engine speeds.

Dual Fuel System

When hydrogen fuel gets over, the system automatically switches to gasoline fuel. Even the driver can manually shift the fuel from hydrogen to gasoline at the touch of a button.

Weight Reduction Technology

Weight plays a significant role in a vehicle’s basic ability to run and stop. Moreover, other factors like fuel economy are also strongly influenced by vehicle weight.

Mazda efforts to reduce the weight of every car it develops. The all-new Mazda2 that was launched in July 2007 says it all. During creating it, each part was examined and any unimportant material was removed. The ultimate vehicle is around 100 kilograms lighter than the 1st generation Mazda2.

Mazda is committed to continuously improving driving dynamics and fuel efficiency by bringing to effect its lightweight technologies and resistance lowering techniques.

A dedicated team has been formed to develop and test weight reduction techniques for the all-new Mazda2 even before the actual development of the vehicle began. The team used updated simulation software to analyze various methods. Then they were tested against vehicle driving dynamics using prototype models.

This advanced technology designed for Mazda’s new compact car resulted in the creation of an amazing concept that uses a new body framework and high tensile steel. Spot welding and weld bonds were also employed to strengthen specific locations that are subjected to greater loads. This has become Mazda’s new approach to weight management.

Weightmazda

Bonnet

With a smaller assembly of the striker and thinner hinges, the bonnet reduces weight by 0.69kg.

Body Shell

Small dimensions only could have lowered the weight of the body shell by 4 kg to 233 kg. Efforts are needed to increase rigidity and crash resistance then would have raised it to 244 kg. But owing to an optimized body structure, weight was reduced to 215 kg, 22 kg less than the old Mazda 2.

Door-Mounted Speakers

Mazda’s weight reducers also worked with the door-mounted speakers. By changing the magnets from a ferrite type to neodymium, and making the plastic molding single-piece, a total weight of 0.98 kg was saved.

Intake and Cooling Systems

For the intake system, Mazda engineers gave a new place to the fresh air inlet. It was removed from its original position behind the left headlamp to the top of the radiator shroud. This new position also helped in weight reduction.

Suspension

Mazda specialists were able to save 13 kg using weight optimizing measures in the suspension.

Exhaust System

Mazda eliminated the underfoot catalyst, and for the 1.3-litre petrol model, the per silencer has also been eliminated from Mazda 2

Other weight reducing measures

The base plate thickness, shift lever assembly and rib configuration for automatic transmission models were also optimized. The shift knob itself was also made smaller and its position was improved. These changes saved 0.85 kilograms.

Hybrid Synergy Drive (HSD) Technology

What Is a Hybrid System?

A hybrid system is a method by which different power sources are used to maximize each one’s strengths while compensating others’ shortcomings.

HSD technology produces a complete hybrid vehicle which allows the car to run on the electric motor only, as opposed to most other brand hybrids which are mild hybrids. The HSD also combines an electric drive and a planetary gear-set which acts similarly to a continuous transmission. The Synergy Drive is a drive-by-wire system with no direct mechanical connection between the engine its controls: both the gas pedal/accelerator and the gearshift lever in an HSD car merely send electrical signals to a computer.

HSD is a modification of the original Toyota Hybrid System (THS) used in 1997 to 2003. The second generation THS II system first appeared on the redesigned Prius in 2004. The name was changed in consideration of its use in vehicles besides Toyota brand. The THS III was implemented in the 2006 Camry, and will be eventually implemented in the 2010 “third generation” Prius, and the 2012 Prius.

The THS III is designed for raised power and efficiency, and also in scalability improvement , wherein the ICE/MG1 and the MG2 have separate reduction paths and are combined in a complex gear which is connected to the final reduction gear train and differential for on all-wheel drive and rear-wheel drive Lexus models.

There are various ways in which electric motors and a gas/petrol engine can be combined.

Toyota did some perfection with the series or full hybrid to yield the energy-saving benefit of a series hybrid together with the acceleration benefit of a parallel hybrid. Two key technologies i.e. the power split device and sophisticated energy management make this possible. They constantly optimize the flows of mechanical power and electric power for safe and comfortable vehicle operation at the highest possible efficiency.

The Full Hybrid

Toyota’s unique hybrid system uses an electric motor and a gasoline engine in the most significant manner. Its fuel saving and reduces emissions while providing ample power.

When the car starts off, Toyota’s hybrid vehicles use only the electric motors, which is powered by the battery, while the gas or petrol engine remaining shut off. A gas or petrol engine cannot yield high torque in the low rpm range, whereas electric motors can deliver a very responsive and smooth start.

Blow Molding Process

In supermarkets, it is increasingly hard to find items packed in glass and jars . A packaging of soft drinks, health care and beauty products, household chemicals and medicines and many other products, have switched from conventional ones to plastics. As the Blow Molding industry has expanded from simple plastic containers to gas tanks, plastic drums, automobile parts and toys in various shapes and sizes.

Blow Molding (BM) process makes it possible to yield molded products economically, in unlimited quantities, with virtually no finishing required. The blow molding process includes a softened thermoplastic tubular form which is inflated against the cooled surface of a sealed mold. The expanded plastic then solidifies into a hollow product.

There are basically four types of blow molding used in the production of plastic jugs, bottles and jars. These four types are:

1) Extrusion blow molding

2) Injection blow molding

3) Stretch blow molding

4) Reheat and blow molding.

blowmoldingprocess

Extrusion blow molding is simplest type of blow molding, where a hot tube of plastic material is dropped from an extruder and captured in a water cooled mold. Once the molds are closed, air is passed through the top or the neck of the container; just as if one were blowing up a balloon.

Injection Blow Molding has very limited and specific applications like making small medicine plastic bottles etc. Extrusion blow molding is the most simple form of blow molding. A tube of plastic material which is generally maintained hot is dropped from an extruder and gets captured in a water cooled mold. Once the molds are sealed, air is injected via the top of the container and the tube is inflated just like a balloon. When the hot plastic material is blown up and touches the walls of the mold the material is then cooled and the container now maintains a solid, rigid shape.

The advantages are many like the tooling costs are very less as compared to injection molding, the part performance is excellent under pressure. The products have awesome environmental stress crack resistance. The products perform great in high-speed impact strength than even the metal components the process can be automatically used in mass production.

The disadvantages mainly increase environmental concerns.
