Research on the Servo Control Strategy of Miniaturized NC Micro-milling Machine Tool Based on Cross-Coupling Control

摘要

The contour precision of the micro-milling machine tool directly influences machining precision of workpieces. This article introduced the cross-coupling control approach applied in micro-milling servo control. Based on a novel miniaturized three-axis NC micro-milling machine tool, the cross-coupling controller was designed and used successfully. The simulation and micro-milling experiment results indicated that the cross-coupling control approach can improve the system contour precision very effectively.
