| Abstract: | In order to measure the end milling temperature of a BT handle tool system,the temperature measurement unit was embedded in the interior of the BT40 handle.A three-dimensional solid model of BT40 temperature measuring tool system was established. With the aid of finite element modal analysis, the dynamic model of the temperature measurement unit was constructed as well. Under the free and constraint states,the frequencies and modal shapes were calculated respectively.The results of finite element analysis and modal experiments show that the dynamic and balance characteristics of the BT40 temperature measurement system can completely meet the demands of the actual cutting. |
