Abstract

In this paper, the thermal characteristics were evaluated in the high-speed ball-end milling of hardened steal (HRe 42). Experimental work was performed to find the optimal cutting environment to increase the tool life at a cutting speed of 210 m/min. Dry, wet and compressed chilled air at -9 and -35 degreesC as the cutting environment were investigated. The implanted thermocouple technique was used for temperature measurement. A K-type thermocouple, implanted in a hole in the workpiece, was directly cut in order to measure the temperatures of the shear zone in the cutting process. The cutting temperatures were about 790, 350, 540, and 450 degreesC in dry, wet, and compressed chilled air at -9 and -35 degreesC, respectively. For the ball-end milling of hardened steel, the cutting environment for compressed chilled air at -9 degreesC provided the best tool life among all the cutting environments. Although the wet condition had the most effective cooling, it provided the worst tool life. (C) 2001 Elsevier Science B.V. All rights reserved.
