Abstract
Conventional collision prevention systems for machine tools are based on simulation methods using 3-D models of materials and jigs which are made in advance. Then, if settings of materials and jigs in the factory are different from the simulation models, collision accidents can not be avoided. Moreover, most collision prevention systems use open NC controllers. Then, these systems can not adapt to usual type NC controllers. Therefore, a collision prevention system for machine tools based on standard technologies is proposed. The system uses materials and jigs measurement data which is gathered using 3-D laser scanner while executing a NC program. This paper describes a concept of the system and development of a prototype system for usual type NC controllers.
