Abstract
This paper investigates how to use cylindrical shape memory alloy (SMA) as chucking part because tool holder can be simplified and miniaturized. SMA material cannot be utilized as chucking tool since it is one-way direction, but it is possible to attach and take off a tool by changing temperature in case cylindrical SMA is made combing cylinder with heat dies steel(SKD6l). It is clear that combing cylinder with cylindrical SMA could resist cutting resistance. Therefore, prototype tool holder that used combing cylinder with cylindrical SMA as chucking part is developed and trice real cutting processes.
