Abstract :
An efficient real-time simulation system for 3-axis NC milling using microcomputers is described in this paper. In this system, the workpiece is represented with an extended Z-map structure and is displayed on screen using isometric projection. After the NC code file was generated and interpreted by an NC instruction translator, a material removal process was simulated just like that performed on real NC milling machine tools driven by NC instructions. The whole process is real-time displayed on the screen; meanwhile alarm messages are given to the operator when interference between milling cutter and workpiece occurs. The simulation result is displayed using a visual realism technique, from which gross programming errors can be checked with ease. The function of each module in this simulation system is discussed in detail using an example. This system simulates NC milling processes efficiently on a microcomputer platform
