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.

Key words: BT40 tool holder, modal analysis, natural frequency, modal shape
