An industry which is continuously evolving in a mechanical sphere is manufacturing. Say it automation, manufacturing or off-shoring, everything contribute to changes in a way products or parts are designed, created and manufactured. Fast, effective design strategies are necessary for companies who want to be in a race with the latest in manufacturing automation.
CAD refers to a design process and is defined by AutoDesk as CAD is the application of computer technology for design and design documentation. CAD/CAM applications are used to both design a product and program yielding processes, mainly CNC machining. CAM software uses the models and assemblies created in CAD software to make tool paths that drive the machines that turn the designs into physical parts. CAD/CAM software is often used to machine prototypes and finished parts.
CAM refers to the application of various software packages to design tool paths and NC code to run a CNC controlled machine, based on a 3D computer model or CAD data. When both of them are used together, this is referred to as CAD/CAM.
CAM does not run the CNC machine. It creates code which it follows. It is not an automatic operation which imports your CAD model and spits out the correct NC code. Similar to 3D Modelling, CAM programming needs knowledge and experience to run a program, developing strategies for machining, and knowing which tools and operations to apply in each situation to get the best results.
Robotic CNC machine tends to provide manipulation and transport options that quite complicate than basic material handling processes. Robots that move machines, take the supply products, sends them to a machine, interacts with the machine and next removes the finished part. As this process is managed by a robot, it minimizes incorrect product placement owing to human error and increases speed and efficiency of production.
Robots and Software
Robots have the ability to cut the total cost of machining by about 30%, according to some studies. But it’s not a simple thing of telling the robot what to perform. Specialized software is needed. One to mention is Siemens NX CAM Software.
According to Siemens, NX provides complete CAM software solutions for machine tool programming, post-processing and machining simulation.
NX CAM is used in many industries, from aerospace and automotive to medical, tool and die, and machinery.
NX CAM and data can process management and establish a basis for an extended part yielding solution. All types of data, that includes, 3D part models, setup sheets, tool lists and CNC output files can be easily managed with full revision control. Data and process management confirms that the right data, which includes correct tooling, and right NC programs are employed, that results in reduced delays and costs.
Getting the Right Data from 3D Models
The integrated CAD and CAM capabilities in NX help the 3D model to move casually between the applications without any data translation. But, it’s essential to prepare the 3D Part Model. The model has to be edited to close holes and gaps, offset faces, and resize part features. Specialized CAD functions in NX helps to quickly analyze the part of CAM programming. With these functions, which include cross section and minimum radius analysis, you can explain optimum machining processes for your parts.
With this, we conclude. To know more, keep visiting this space.
