STUDY OF FIVE-AXIS COMMERCIAL SOFTWARE POST-PROCESSOR CONVERSION APPLIED TO A PARALLEL FIVE-AXIS MACHINING MACHINE

This study developed a five-axis machine center that integrates two mechanical models: a three-degree-of-freedom parallel platform and traditional computer numerical control (CNC) X–Y table. In the design of the mechanism, the three actuator axes are parallel to each other, and the two platforms are installed in parallel. The positions of the moving platform are changed by extending and shortening the three axes. To verify the machining precision and usability of this machine, this study used the post processing program to transfer the numerical control code using five-axis machining software to determine the processing path; the Z, α, and β values of the numerical control program are used to convert each axis value of a three-axis motion platform through inverse kinematics. Finally, this study used two machining methods in the design: actual concentric roughing and actual spiral roughing. Machining experiments were conducted to verify the accuracy of the proposed method.
