TOOL COLLISION DETECTION IN MACHINING USING SPATIAL REPRESENTATION TECHNIQUE

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