Course abstract

The aim of the study course is to get acquainted with the CAM system. Students acquire 3D modelling and project the processing of cutting tool trajectories. Students get acquainted with 3D surface processing, the technological process of the production of components (parts) in the regime of „Surface High Speed”. Students acquire the application specification of digital control working machines in the manufacturing of complicated form parts on CNC machine tool benches, as well as get acquainted with the latest development tendencies in MasterCam.

Learning outcomes and their assessment

Knowledge - functions and capabilities of MasterCAM software (1 test).
Skills - to design cutting tool machining trajectories and to plan the workpiece machining sequence in 3D environment, to create programs for machining parts on CNC control machines (5 practical works).

Competence - to analyse the quality of machining technology and evaluate the economy of workload (5 practical works).
