Abstract

We conducted milling experiments of Ni-based super alloy by use of the developed milling cutter with Self-Propelled Rotary Tool (SPRT). Experimental results verified that the tool life is increased 12 times as compared with the conventional milling without insert rotation due to tool wear suppressions. Cutting process parameters were also identified by inverse analysis of the cutting forces. The identified parameters may be available for advanced estimations in tool geometry and machining quality. On the other hand, disadvantageous characteristics in ramping process were revealed due to flank face contact.
