The Experimental Design of Testing Turning Temperature of the Moderate Wear Tool
【Abstract】In the process of turning，tool wear will affect the processing precision of the workpiece. And it has a very close relationship between the tool wear and turning temperature. This article is aimed at moderate wear tool case，to study the relationship between turning temperature and turning depth，spindle speed and feed rate among. In the experimental study，we used principle of infrared temperature measurement to built a tool temperature monitoring system. We real-time recorded the temperature changes of the tool tip. By analyzed the recorded data，we studied the influence of moderate wear tool turning temperature by turning depth，spindle speed and feed rate. The results show：(1)Under the condition of different feed rate，temperature gradually increased with time.The temperature is similar when the feed rate are 40mm/min and 80mm/min；the temperature rise sharply when the feed rate is 160mm/min.(2)Under the condition of different turning depth.When the feed rate is constant and spindle speed changes，turning the deeper the depth，the higher the temperature；When the spindle is constant and feed rate changes，temperature has a tendency of increasing in general.(3)Under the condition of different spindle speed.The fluctuation of temperature curve is slightly larger.But in general,the temperature is increased.
