Abstract:This paper deals with the virtual modelling and simulation of a complex CNC machine tool feed drive system. The first phase of the study was the modelling of a very complex structure of the feed drive which consists of many elements (position, velocity and current control regulat...

Abstract:One of the most important factors which influence on the dynamical behavior of the high-speed feed drives for CNC machines is position loop gain or Kv factor. It directly influences the contouring accuracy of the CNC machines. Usually position loop gain is experimentally tuned on...
