Influence of Process Variables on Cutting Induced Workpiece Temperature in High Speed Milling of Al- Si-Mg-Fe Alloys Using Taguchiís Technique

Abstract

In this paper, the experimental investigation was carried out with straight flute end milling cutters for high speed end milling of the Al-Si-Mg-Fe alloy materials. Machining induced workpiece temperatures can be controlled by changing the machining conditions. For determining the distribution of workpiece temperatures for end milling of aerospace aluminum alloys used. The cutting temperature depends upon the cutting speeds, depth of cuts and feed rates. The cutting temperature increases with an increase in the depth of cut and feed rate and decreases with an increase in the cutting speed. Machining of Al-Si-Mg-Fe alloy should be carried out at high speeds and feeds to minimize temperature rise in the work piece. The long term effects of continuous heat input from the cutting tool should affect workpiece material properties due to the accumulated rise in temperature of the work piece. This behavior can be attributed to the precipitation hardening and thermal stability in the alloy.
