This paper suggests a new mathematical method to calculate volumetric machine tool motion errors using rigid body kinematics. Different internal and external heat sources lead to a nonhomogeneous transient temperature distribution within the machine structure. This results in transient tool-center-point deviations during measurement time, directly affecting the measurement uncertainty. Therefore investigations...
This paper focusses on the volumetric thermo-elastic machine tool behavior. In particular environmental influences and internal heat sources like linear axes lead to inhomogeneous temperature distributions within the machine structure and results in a positional dependency of tool-center-point (TCP) deviations. Therefore a measuring method using tracking interferometers to characterize the volumetric...
