Tool collision detection in machining using spatial representation technique

Abstract

The objective of this research work is to develop a tool collision detection system for turning operations. Spatial representation technique is used for object representations of cutting tool, workpiece, workholding device and machining envelope to detect intersection or interference between solids. The algorithm, developed using Turbo C++, is able to detect various types of collisions and to modify the machining envelope to avoid collision. The algorithm is also able to determine the cutting tool efficiency based on the machining envelope. The effectiveness of the method has been illustrated with an example.
