Abstract
Finishing processes such as deburring are performed on a wide variety of products in various quantities by workers on a piece-by-piece basis. Accordingly, the accuracy of the product depends on the worker's skill. To solve this problem, the bilateral control system is applied to machining support system. The aim of this research is to develop a machining support system via bilateral control system which can control the machining trajectory by reflecting the operation force. This system has the variable connecting force construction for master and slave robot based on the symmetrical bilateral controller. This construction is useful to change the feature of system according to machining condition dynamically.
