Summary
The aim is to use computer programming numerically controlled machine tools with a focus on the method of programming using CAD / CAM systems, ie systems that use computer-aided manufacturing. The course is a general understanding of laws, procedures and information regarding the CAM system, includes enhanced knowledge of programming NC machine tools aimed at extending the basic strategies of 3-axis milling, additions and extensions of the accompanying documentation and advanced simulation and verification, and also includes multi-axis programming (4-axis turning, turning with driven tools, milling and indexed the basics of programming 5 axis continuous) and generate NC code for the machine tool and build the necessary accompanying documentation needed for production.
