Popis:	We present extensions to our prior work in modeling and correcting for pretravel variation errors m kinematic seat touch-trigger coordinate measuring machine (CMM) probes with straight styli. A simple correction term is shown to account for a ran e of probe assymetries quantitatively, leading to improved error compensation. We also demonstrate probe lobing correction for constrained fits to small datasets, illustrating practical examples for both CMM and machine tool probes. Finally, we discuss statistieal and uncertainty issues and demonstrate the effectiveness of the model with actual measurement data.
