During the study course students get acquainted with the CAM system, prepare programs for mechanical processing of workpieces. Students learn the modelling of the cutting process and design the cutting trajectories of the cutting tool.
Knowledge. Students are familiar with graphic analysis and representation, understand the creation of sketches of ideas, detailed drawing-plan, preparation of drawings, three-dimensional visualization of objects. (1 test)
Skills. Students acquire skills to independently use the functions and possibilities of MasterCAM software to compile a CNC machine control program in the part manufacturing process. (4 practical works)
Competence. Ability to understand the specifics of different manufacturers and the levels of complexity of series product design, to know the necessary machines, tools and equipment. (4 practical works)

Part time extramural studies:
All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar
1. Successful assessment in tests.
2. Passed practical and laboratory works during workshops.
3. Evaluation of reports in classes.
Accumulated test with a mark.
Practical work in CNC program development using MasterCAM.
1. The student gets successful mark in the test if at least 50% of the questions are answered.
2. Practical works are done and defended in time.
Final mark (accumulative test with mark) average mark of tests and practical works.
