Development of hi-speed and hi-accuracy machining system based on NC geometric cutting simulation

Validation case study of basic system

Abstract

The purpose of this research is to develop hi-speed and hi-accuracy machining system. The servo data is the set of position command at every servo cycle time, which is minimum unit of position command in NC machining processes. The servo data is directly generated by geometric model interpolation without NC program. In this research the tool path generation system that is able to predict and compensate the tool deflection and fluctuation of cutting load is proposed. This report refers to the algorithm to calculate the removal volume in consideration of a tool deflection.
