MACHINE TOOL WITH OPTICAL MEASUREMENT DEVICE FOR THREE-DIMENSIONAL REFERENCING BETWEEN THE TOOL HOLDER AND THE WORKPIECE SUPPORT AND CORRESPONDING THREE-DIMENSIONAL OPTICAL MEASUREMENT METHOD

摘要

The invention relates to a machine tool comprising a machining module (300) equipped with a tool holder (310) and with a workpiece support (320), and an optical measurement device (10) for the three-dimensional measuring of the relative position between the said tool holder (310) and the said workpiece support (320), the said optical measurement device (10) comprising an optical system (100) mounted on the workpiece support (320) and a target (200) mounted on the tool holder (310) and comprising a working face (202) forming a positioning reference that can position itself on the optical axis (O) of the optical system (100).
