Research Abstract |
A newly developed infrared radiation pyrometer equipped with two optical fibers is used to measure the cyclic temperature variation beneath the rake face of a cutting tool in end milling. A theoretical analysis is conducted using a semi-infinite rectangular corner model. In up milling, the temperature beneath the rake face increases gradually during the cutting period and reaches a maximum just after the cutting. In down milling, the temperature increases immediately after cutting starts ; it reaches a maximum and then begins to decrease during cutting. The temperature gradient toward the inner direction of the tool insert is about 300 degrees Celsius per 0. 5 mm. The effect of a cutting time on a tool wear is small
