On Cutting Characteristics Change of Low Temperature Cooling Tool(1st Report) - Cutting Characteristics of Cage Motor Rotor -

저온냉각공구의 절삭특성 변화 (제1보) -모터 회전자의 절삭특성

The cutting process of cage motor rotor require high precision and good roughness. The surface roughness of cutting face is very important factor with effect on the magnetic flux density of cage motor rotor. The paper describes a cause of decrease in the cutting force and roughness on low temperature cooling tool by means of analysis on the mechanism of force system at cutting confition and experimental findings. The main results as compared with the room temperature cutting are as follow : 1) The cutting resistance decreased due to low temperature cooling tool. 2) The surface roughness decreased due to low temperature cooling tool.
