Hot machining in end milling of hardened steel AISI D2
A study was performed to investigate the performance of coated carbide inserts in end milling of AISI 02 hardened steel (60-62 HRC), under room temperature and workpiece preheated conditions. The effects of cutting conditions on tool wear morphology and machined surface finish were also investigate...

| description |
A study was performed to investigate the performance of coated carbide inserts in end milling of AISI 02 hardened steel (60-62 HRC), under room temperature and workpiece
preheated conditions. The effects of cutting conditions on tool wear morphology and machined surface finish were also investigated. Tests on end milling were conducted on
a vertical machining Centre (VMC) to ascertain the relative advantages and drawbacks of applying workpiece preheating in the process of machining using induction heating.
Preheating of the work material with higher heating temperatures (250-450 OC) gives significant improvement in terms of maximum tool wear. Average uniform wear at the
flank surface is found to be lower in the case of preheated machining of 335 - 450 deg C temperature. Abrasive wear, notch wear and diffusion wear are found to be very prominent mechanism of tool wear. It has been observed that preheated machining of the material leads to surface roughness values well below 0.4 urn, such that the
operations of grinding as well as polishing can be avoided at the higher cutting speed |
