Degree, but owing to workpiece is to separate, it is difficult to the temperature accurately obtained in working angles in workpiece；According to infrared thermography,
Optical fiber infrared thermometry measures cutting temperature from cutting out side, then be difficult to accurately obtain the temperature value at cutting edge.
Application No. CN201310072128.4 invention profit application documents disclose a kind of for drill for high-speed processing
Cutting temperature measurement device, this temperature measuring equipment can measure the temperature at drilling process apex point.But this device cannot measure milling
During the temperature of milling edge, be not suitable for the measurement of the transient temperature of milling edge during side milling of the present invention.Additionally,
Also the synchro measure of course of processing workpiece temperature cannot be realized.
