Abstract

CNC milling machines are widely used in manufacturing processes. In time, their accuracy is decreasing, which directly influences the accuracy of the manufactured parts. This research proposes a simulation-based method for improving the accuracy of the above mentioned machines, which is suitable to be applied at the shop floor level. A model of the feed drive, using a dc servomotor as actuator, is the core of the proposed approach. Matlab & Simulink based simulation diagrams were built in order to test the behavior of the system.
