Abstract
Circular vibration milling (CVM) has been proven capable of producing better surface finishes on difficult to cut materials. However, CVM process is far slower than conventional milling process. In circular vibration planing (CVP) process, the cutting tool is clamped without rotation and fed at a speed comparable to the feed speed of conventional milling. By superimposing circular vibration motion, necessary cutting speed could be achieved keeping the feed speed at realistic values. Inconel 718 was machined by CVM, CVP and conventional milling. It was observed that CVP could reduce tool wear and hence produce better surface finishes than conventional milling.
