CAD/ CAM
Computer-aided manufacturing (CAM) refers to the use of software independent of the CNC machine to create the NC code and is a sub-aspect of manufacturing technology.
Instead of conventional drawings, the NC program for the part to be produced is to be created directly on the basis of the CAD data produced on the computer. The necessary instructions for the CNC machine and the instructions for the operators should no longer have to be printed out, but should be transferred to production in electronic form.
The NC code is used, for example, to control metal-cutting machines or 3D printers. In contrast to the creation of the NC code in the workshop (WOP), with the CAM system the NC program is already created in the work preparation. CAM is an essential component of computer-integrated manufacturing (CIM).
