Development of Micropositioning System Using a Magnetostrictive Material

자기변형재료를 이용한 마이크로포지쇼닝 시스템의 개발

In this machining process, variation in cutting forces results in relative displacements between the tool and the workpiece leading to tool vibration. Also there is a demand to change the depth of cut very frequently. A soluion for both cases is to develop a system which has the ability to reposition a cutting tool to a very small level, i.e., micron. This ppaper presents the development of a micropositioning system (MPS) using a magnetostrictive material. The deveoped MPS is implemented to a lathe and subjected to static and machining test. The results show that the MPS has good potential for machining application
