| Outline of Final Research Achievements |
The objective of the present research is to establish a computer-aided design system for specifying a suitable set of the geometric tolerances of the guide-ways considering the trade-off between the requirements on the kinematic motion deviations and the ease of the manufacturing processes. A mathematical model is proposed to represent the standard deviations of the shape generation motions, based on the tolerance values of the guide-ways of the machining centers. A systematic method is proposed here, by applying an optimization method, to determine a suitable set of the tolerance values of the guide-ways under the constraints on the kinematic motion deviations. The method is applied to some design problems of the geometric tolerances of the guide-ways included in the five-axis machining centers. The same method is expanded and applied to the tolerance design for the parallel link robots used for the precise and small product assemblies.
