Abstract:A new kind of numerical control (NC) system for machining shafts with non-circular cross-section is proposed in this paper. It is composed of one X-Z platform, a special micro-feed mechanism driven by a simple cam, and one rotating tool. A new circumferential curve interpolation algorithm based on the cam mechanism is put forward to machine the shafts with any non-circular cross-section, and its efficiency is verified by the simulation. Especially, the larger cutting force can be obtained by use of individual … Show more
