Aims and objectives: To present a problematic of the technological preparation of manufacturing process and NC machines programming. To approach the principle of tool preparation for NC machines, automation tool exchange systems, their coding, tool store, manipulation with workpiece. To provide the theoretical background of the automation programming from the view of the processor structure, postprocessor structure etc. From the practical view to enable for student the preparation of entering media – enter data for PC, program debugging, simulation of program on PC, start-up of NC machines at the various modes.
Course content: Flexible automation of the mechanical engineering manufacturing and pre-manufacturing stage.
