Abstract
A method for machining a selected part with a machine tool, comprises obtaining a master part replicating at least a portion of a geometry of a selected part. The master part is loaded in a machine tool. A signature of the machine tool is defined by measuring at least dimensional data of the master part relative to the machine tool, the dimensional data being limited to a selected-part-specific working volume substantially smaller than a complete working volume of the machine tool. The machine tool is certified as being within tolerances to machine the selected part within the working volume, using the dimensional data of the signature. The selected part is machined from a workpiece with the machine tool.
Claims11
A method for inspecting of a machine tool having a working volume, the method comprising:
- measuring initial dimensional data of a master part disposed in a part-specific working volume relative to a reference of the machine tool, the part-specific working volume being substantially smaller than a complete working volume of the machine tool;
- when the master part is removed from the machine tool, machining at least one part with the machine tool;
- after machining the at least one part with the machine tool, measuring subsequent dimensional data of the part-specific working volume relative to the reference of the machine tool;
- comparing the subsequent dimensional data to the initial dimensional data;
- and
- certifying the machine tool when the subsequent dimensional data is within predetermined tolerances of the initial dimensional data.
