Abstract
The paper describes the conceptual design study on the process planning support system for machining parts of machine tool systems. The system aims the full and direct utilization of 3D solid model part data obtained in the design process of a machine tool and the realization of computer based processing chain to generate the process and operation plans to machine parts as well as all necessary information for CNC parts machining operation including CNC programs and machine set-up data). The paper contains the background of the study, the concept of the system and the expected outcome to be obtained from the study, and general flow of the proposed process planning support system.
