- Abstract
- The shortest tool setting is recommended to reduce the tool deflection and chatter in NC machining. However, it is not easy to shorten the overhang length because the holder can collide with the workpiece. In this paper, the safe and shortest tool-setting algorithm using a safe space is proposed and applied in NC machining. The safe space is the volume in a tool coordinate system that does not interfere with the workpiece and the holder located in the safe space never collides with the workpiece. So the tool holder assembly that has the shortest overhang length and does not interfere with a workpiece is possible using the safe space. This algorithm was implemented with C++ language and has been used by over 50 mold-machining companies for safe and short tool setting.
