The objective of the research is to establish mathematical models representing the kinematic motion deviations of the machine tools on the basis of the geometric tolerances of the components, and to apply the models to theoretical analysis of the kinematic motion deviations of the machine tools. Mathematical models are proposed to represent the kinematic motion deviations of the linear tables of the machine tools. The proposed models give the relationships between the geometric tolerances of the guide-ways of the components and the kinematic motion deviations of the linear tables. The models of the linear tables are combined to represent the whole machine tools to represent the positional deviations of the tools against the workpieces. The developed models are applied to the analysis of the kinematic motion deviations of the machine tools, aiming at clarifying the effects of the geometric deviations of the components on the kinematic motion deviations between the tools and the workpieces.
