What I s Computer - Aided Producturing (CAM)?

Komputer- Aided Producturing refers tich use of computare tlo control machine tools andcoordinate producturing processes. It translates three-dimensional computer-aided desin (CAD) models into precise sets of instructions - typically G- code - that drive CNC mills, lathes, wire EDM machines, and additiva producturing equipment. In the EV powertrain context, CAM ensures that complex geometries, hint tolerances, and specized material expeciments are met consistents.
