During the coordinate measurement and surface quality inspection processes conducted by touch-trigger probe on CNC machine tools

conventional measurement methodologies demonstrate suboptimal efficiency when acquiring workpiece coordinates for components with predefined surface coordinate ranges. To address this problem

an axial measurement coordinate optimization method based on kinematic modeling of the probe-workpiece interaction is proposed. First

based on the kinetics model of the CNC control system and the probe measuring mechanism

a probing kinetics model and a measuring error model are built. A high feedrate measuring error compensation method is proposed. Then a group of tests are carried out with a Renishaw OMP probe on a Bridgeport vertical milling machine to verify this proposed approach. The tests results demonstrate that this approach can precisely measure parts coordinates in high feedrate. Compared to the existing methods

this method reduced the measurement time for workpieces from 9.36 s to 0.36 s with the same measuring precision.
