Cutting Forces during Precise Turning of NiTi Shape Memory Alloy

The selected indicators of machinability of NiTi based shape memory alloys has been examined. The paper presents research of possibilities of shape memory alloy like low-temperature (austenitic) Ni53Ti47 (Nitinol) with a coated cemented carbide tool, cutting force components (F_f–the feed force, F_p–the passive force, F_c–the main cutting force). In the work, a special attention was paid on the main cutting force components at variable cutting speed (v_c).
