Open Architecture Modular Tool Kit for Motion and Machining Process Control

Abstract

An open and reconfigurable modular tool kit is presented for the design of CNC systems for machine tools and machining process monitoring. By selecting standard commands from the software tool kit library, the user is able to design a new CNC system automatically. The developed system allows integration of user developed program modules to the tool kit library. The developed CNC is based on a fully integrated, open, real-time, preemptive DSP operating system and a Windows NT application. It has hardware independent architecture, and supports multiple DSP boards and multiple host computers for machine tool and robot drive motion control, trajectory generation and sensor based machining process control and monitoring applications. The system can be quickly configured to control different machine tools, robots and sensor based processes by selecting standard script commands from the design library. The paper contains sample applications for machine tool control and sensor assisted machining applications.
