Course abstract

Application of wood processing technologies in programming machine tools. Processing trajectory preparation for programmatic (CNC) working machines using CAM software. Construction and operational principles of machine management (CNC) working machines. Basics of programming. Learning practical skills in working with automated processing trajectory (CAM) preparation software and various types of wood processing programming equipment.

Learning outcomes and their assessment

Learned knowledge of the operating principles of software equipment (CNC), uses and working time planning, processing trajectories, and parameters, cutting technologies and cutting instruments and processing quality assessment (Test 1 and 2). Acquired skills in testing and preparing CNC equipment for work, equipment, cutting and processing parameters, in preparation of wood-based wood-based material processing trajectories using CAM software (Test 1). Obtained skills in producing a product with CNC in the assessment of equipment, accuracy and surface processing according to the task (Practical Works).

Criteria for Evaluating Learning Outcomes

The assessment of knowledge, skills and competence takes place in a 10-grade scale. An oral or written answer shall be successful if at least 50% of the questions answered correctly.
The course rating is a cumulative assessment of 2 tests (50 % from total) and practical work (50 % from total) assessment.
