A Practical Approach to Estimating Corner Errors in Contour Cutting with Machining Center

This paper proposes a practical approach to estimating the corner errors in contour cutting with a machining center. In this approach, only a few simple and easy trajectory measurements to linear feed motion of machining center are required and then the value of each necessary parameter is decided through a simple operation to the measured data. The comparison results of the estimated corner errors with the measured ones sufficiently demonstrate the effectiveness of the proposed approach.
