What is the meaning of cam in computer-aided systems?

The meaning of cam in computer-aided system is computer-aided manufacturing.

CAM (computer Aided Manufacturing) mainly refers to the use of computers to assist in completing the entire process from production preparation to product manufacturing, that is, by directly or indirectly connecting computers with the manufacturing process and production equipment. Contact, use computer systems to plan and manage the manufacturing process, control and operate production equipment, process data required in the product manufacturing process, control and process the flow of materials (blanks and parts, etc.), and test products and inspection etc.

It includes many aspects, such as Computer Numerical Control (CNC), Direct Numerical Control (DNC), Flexible Manufacturing System (FMS), Robots, Computer Aided Process design (Computer Aided Process Planning, CAPP), Computer Aided Test (CAT), Computer Aided Production Planning (Production Planning Simulation, PPS) and Computer Aided Production Management (CAPM), etc.

This is a broad definition of CAM. The narrow concept refers to all production preparation activities from product design to processing and manufacturing, including CAPP, NC programming, calculation of working hours quota, formulation of production plans, formulation of resource demand plans, etc. This is the narrow concept of the original CAM system. Today, the narrow concept of CAM has even further narrowed to a synonym for NC programming. CAPP has been regarded as a specialized subsystem, and the calculation of working hours quota, the formulation of production plans, and the formulation of resource demand plans have been assigned to the MRPⅡ/ERP system. The broad concept of CAM includes much more content. In addition to all the content included in the narrow definition of CAM mentioned above, it also includes the monitoring of all logistics-related processes (processing, assembly, inspection, storage, transportation) in manufacturing activities. , control and management.

The above is the detailed content of What is the meaning of cam in computer-aided systems. For more information, please follow other related articles on the PHP Chinese website!
