SHAPE MEASUREMENT DEVICE FOR MACHINE TOOL WORKPIECE

WIPO Patent Application WO/2011/132315

A1

Disclosed is a shape measurement device for a machine tool workpiece that is capable of measuring in a short period of time in comparison to cases using a high precision sensor exclusively and is capable of measuring a prescribed spot with high precision, which is equipped with a wide range sensor (11) that is capable of measuring across a wide range, a first workpiece model generator (13) that generates an approximate 3D shape of the workpiece (1) on the basis of data measured by the sensor (11), a high precision sensor (12) that is capable of high precision measurement, a second workpiece model generator (14) that generates a high precision 3D shape of the workpiece (1) on the basis of the data measured by the sensor (12), and a workpiece model integrator (15) that generates an entire 3D shape of the workpiece (1) by replacing, on the basis of the approximate 3D shape of the workpiece (1) and the high precision 3D shape of the workpiece (1), spots on said approximate 3D shape of the workpiece (1) that match the high precision 3D shape of the workpiece (1) with the said high precision 3D shape of the workpiece (1).
