A high speed machining algorithm for CNC machine tools

This paper introduces a high speed machining algorithm based on a look-ahead interpolation technique for the machining of 3D surface obtained by a CAD/CAM system. Generally, specification of CNC system for high speed machining requires an additional hardware and it burdens end users with additional cost. The purpose of this research is to develop the low cost CNC controller having the high speed machining ability. The experimental results demonstrate that the proposed algorithm improves the machining speed in the program consisting of small line blocks without any hardware support. To investigate the performance of the introduced algorithm, the authors implemented it to the machining center equipped with Samsung SNC that consists of a 64 bit main processor and a 32 bit floating point DSP as the motion control CPU.
