A study on torelance design of five-axis machining centers

The objective of the research is to establish a systematic design method applicable to analysis and design of kinematic motion deviations of five-axis machining centers based on the tolerances of the guide-ways. A systematic procedure is proposed to determine the tolerance values of the guide-ways theoretically under the constraints on the kinematic motion deviations of five-axis machining centers, by applying ISO Tolerance definitions. The proposed method provides us with theoretical way to design the geometric tolerances of the guide-ways connecting the components of five-axis machining centers, based on allowance of the kinematic motion deviation of the tools against the workpieces.
