Development of Reconfigurable Five-axis Machine Tool Using OPEN Computer Numerical Control System Integration Architecture

摘要

The purpose of this study is to use an OPEN computer numerical control (CNC) system to develop a reconfigurable five-axis machine tool (RFMT) for system integration research. The RFMT is mainly composed of a three-degree-of-freedom (3DOF) parallel platform and an X-Y table. In the study, the human-machine interface of OPEN CNC was written, and the programmable logic controller (PLC) architecture of OPEN CNC is used to control three-axis simultaneous movement or individual drives. The processing path of this study uses a postprocessing program to transfer the numerical control (NC) code with five-axis machining software, and the Z, α, and β values of the NC program are used to convert each axis value of a three-axis motion platform by inverse kinematics. Finally, rough and finishing methods are used to cut a concave circle to verify the accuracy of RFMT.
