| Abstract |
Using solid carbide straight end mills with TiAlN coating, A P20 steel at 41HRC is
machined in the cutting speed range of 301 to 754m/min. The workpiece subsurface are examined
using scanning electron microscope (SEM) and surface roughness tester. The results show that the
white layer is produced in all of the cutting conditions tested, and the white layer thickness and
surface roughness are dependent on the cutting conditions. The result obtained by analysis of
variance analysis shows that feed rate and cutting speed are the most significant effects on the white
layer thickness and surface roughness. Furthermore, the mathematical models for the white layer
thickness and the surface roughness in high speed side milling of hardened P20 steel are proposed,
respectively. |
