Geometric Calibration of Machine Tool Based on Auto-Trilateration

Abstract:

In this paper, an innovation method to describe the geometrical error of the machine tool based on trilateration is proposed. This method can be carried out by measuring the interferometric displacement between reference point and offset point of spindle. The experimental result has been compared with that of laser interferometer under the same CNC machine-tool, and both of them can achieve the satisfied result. Therefore this scheme can be applied to a more sophisticated situation. What’s more, there is no limitation to the maximum size of the working volume. Without the calibration equipment, it can be easily evaluated with simplified data structure.
