Machined Surface Roughness Geometry Model Development on Ultrasonic Vibration Assisted Micromilling with End Mill

Abstract

Micro products or micro components are commonly used in today’s world. Research around micromanufacture technologies to produce a better product quality has been going on extensively. Ultrasonic vibration assisted micromilling (UVAM) is one of the technologies that can give a better machining qualities over the conventional ones. One of the benefits UVAM can give is reducing the machined surface roughness. The purpose of this paper is to give an idea how vibration assisted micromilling can give a better surface roughness quality. The theoritical surface roughness geometry model is made using MATLAB software. The cutting tool used in the simulation is end mill. There is a feature of the cutting tool called bottom cutting edge angle. This feature will be considered on this paper. The effects of the bottom cutting edge on workpiece machined surface can be looked visually from the simulation. Thus, the effects of cutting process using UVAM on the workpiece surface can be looked as well through the simulation.

Experimental Investigation on Axial Ultrasonic Vibration Assisted Milling of Cr12MoV

“…The ultrasonic processing technology has attracted the attention of scholars and achieved a lot of results [11]. The ultrasonic vibration assisted cutting is one of promising ultrasonic technique, which showed that have great advantages over the conventional cutting, like lower cutting forces, higher machining stability, less tool wear, and a better quality [12,13]. It has been widely used due to…”
