Abstract: The present disclosure generally describes a method for processing a workpiece in a machine, where the method determines an offset of the machine and adjusts for the offset during production operation. In one form, the method includes logging offset data of the machine over a period of operational time having varying thermal conditions, and comparing the logged offset data against a thermal model, where the thermal model is generated based on a probing routine and dry cycling for a plurality of test cycles on a calibration artifact. Based on the comparing, the method estimates offsets for the machine and adjusts offsets of the machine during operation.

Abstract: A fixture clamp adjustment system includes a test workpiece and an alignment block. The test workpiece has a load cell and is configured to nest upon a fixture that has a clamp such that the load cell aligns with the clamp when open and such that the clamp contacts the load cell when closed. The alignment block is configured to couple with the clamp and engage the test workpiece when the clamp is closed to maintain clamp and load cell alignment.
