It is well known that the cutting motions of a machine tool can be expressed by a combination of homogeneous transformation matrices. One such combination, called the form-shaping function, relates both the machine tool structure and the product shape to the machining tolerance. This function allows the prediction of machining tolerances based upon knowledge of the machine and product geometry. This paper first describes a generalized procedure used to obtain the form-shaping function. Then, the Taguchi method is applied to the form-shaping function of a T-base lathe. The goal is to identify which physical dimension of the machine most strongly influences its tolerance-holding capability. The numerical results for the T-base lathe indicate that the distance between the spindle center and the base is the most critical parameter for improving machine robustness. The results also lead us to conclude that the Taguchi method is useful in determining an optimum design strategy for a machine tool.
