214 Scheduling Systems by Using 3D CAM Aimed at High Production Efficiency for 5-Axis Machine Tools

Abstract

In order to realize the efficient manufacturing thorough intensive manufacturing processes, 5-axis machine tools attract a wide attention. New scheduling systems are proposed by using 3DCAM aimed at high production efficiency for 5-axis machine tools, in this research. The scheduling systems consist of 3axis and 5axis CNC machine tools, 3DCAD database, Customized 3DCAM corresponding to types of machine tools, and the jobs. The proposed scheduling systems carry out following 3 steps. The individual machine tools refer the 3DCAD database to obtain the 3DCAD data of jobs which can be carried out next machining process in the first step. 3DCAM creates the NC data and estimates processing time of all jobs in second step. The individual machine tools and jobs carry out the autonomous distributed scheduling process in order to minimize the make-span in third step.
