With the increasing demands for higher efficiency and machining accuracy in the manufacturing system, the workpiece chucking technology has recently become important. This trend is especially accelereted with the advance of the FMS (Flexible Manufacturing System) technology. The workpiece chucking technology, such as a multiple-jaw chuck greatly affects both the geometrical accuracy and functional performance of the workpiece. In order to enhance the chucking technology of the future, it is necessary to investigate and evaluate the performances of the conventional chuck at first. However, research activity on the conventional chuck is not sufficient enough as yet to solve the problems so far suggested. In this paper, therefore, the fluctuation of the chucking force during non-cutting and cutting has been investigated using the three-jaw chuck of wedge type. In addition, the relationships between the chucking force and the thermal deformation of the workpiece have been measured to clarify the cause of the fluctuation of the chucking force.
