Prototyping of Autonomous NC Machine Tool Based on Digital Copy Milling Concept

Abstract

A prototype of NC machine tool which realizes autonomous milling operation was developed. The machine tool developed is controlled by the digital copy milling concept. In the digital copy milling concept, not only feed speed, but also radial and axial depths of cut can be adapted for milling process control. Also, new tool paths can be added to avoid and recover from cutting troubles without any NC program. The experimental milling was performed successfully to show the effects of milling process control and tool breakage avoidance.
