Practical work to develop a system capable of shape-adaptive cutting is carried out. The system consists of a shape-recognizing unit, a data-processing unit and a lathe-driving unit. The system is established based upon an inherent ability of the NC lathe, although several methods have been developed in other investigations to control the tool post using exclusive mechanisms for achieving a non circular profile on a rotating workpiece. To draw out the full ability of the NC lathe, a new approach, called the direct control method, has been taken. In this method, servo mechanisms of the NC lathe are incorporated as inherent elements of the system, and controlled directly by pulse signals generated by a personal computer. In this paper, the construction of the shape-adaptive cutting system and the workings of each part are shown. Moreover, parameters that govern the dynamic characteristic of the tool post are determined on the basis of the result of the computer simulation. Subsequently, the system is tested. The result of tests demonstrates that the shape-adaptive cutting system is applicable to manufacturing.
