Investigating the Cutting Mechanics in 2 Dimensional Ultrasonic Vibration Assisted Milling towards Chip Thickness and Chip Formation

Abstract

A high quality and precise machine and tool component is needed to produce the desire product. In order to manufacture in the shop floor machine factory, it significant to find the best solution with taking into account the tool condition, tool failure, thermal softening and surface finish etc. The purpose of this paper is to investigate the effects of 2 dimensional Ultrasonic Vibration Assisted Milling (UVAM) cutting mechanics, considering tool path trajectory and the effect on the chip thickness. The theoretical modelling of cutting mechanics is focused by considering the trajectory of the tool locus into the workpiece during the machining. The studies found the major advantages of VAM are come from the intermittent tool tip interaction phenomena between cutting tool and workpiece. The reduction of thinning chip thickness formations can be identifying advantages from vibration assisted milling in 2 dimensional. It is discovered that the main increase in cutting force reduction, temperature reduction, increased tool life, discontinuous, thinning, and improvements in chip formation, and improving surface roughness resulted from the effect of the tool entering and disengaging from the workpiece.
