Development of a High-speed and High-precision Parallel Mechanism Machine Tool

Abstract

Generally the control parameters for parallel mechanism machine tool are adjusted under the lowest machine rigidity because it varies with each position and posture of the spindle. However, it is possible to obtain higher speed and precise positioning by using the optimal control parameters at a higher machine rigidity. We have developed the function to optimize the control parameters with the position and posture of the spindle accordingly, therefore, higher speed and accuracy could be achieved.
