概要:

The temperature of cutting tool in high speed endmilling is measured using a two-color pyrometer with an optical fiber. This pyrometer has a flat response for the square-wave signal up to approximately 400kHz, which is enough speed to measure the temperature of an endmilling cutter passing at a cutting speed of 628m/min. The influence of cutting speed v and feed per tooth f on the cutting temperature at the flank face of the cemented carbide insert is investigated. … The heating and cooling characteristics of the cutting tool during an intermittent cutting cycle are also examined. In dry cutting of carbon steel, the cutting tool temperature θα rises rapidly with the increase of cutting speed and θα reaches approximately 770°C at v=628m/min. The feed per tooth, however, has less effect on cutting tool temperature. The temperature change during an intermittent cutting process is about 150°C when v=471.2m/min and f=0.047mm/tooth. The temperature distribution along the contact edge between a tool and workpiece is almost uniform although those at tool tip and boundary region are somewhat higher. 続きを見る
