NUMERICALLY-CONTROLLED MACHINE TOOL

WIPO Patent Application WO/2012/029436

A1

Provided is a numerically-controlled machine tool (100) provided with: a tool measuring sensor (104) that measures the length and diameter of a tool (101); a workpiece measuring sensor (105) that measures the three-dimensional shape, and position and orientation of a workpiece (1) in a non-contact manner by laser beam etc.; and a control device (106), which, after determining the position of the machining starting point and the slope of a reference plane on the basis of information from the workpiece measuring sensor (105), on the basis of an inputted machining program, controls the movement of a main axis (102) etc. such that the workpiece (1) is machined from the information from the sensors (104, 105), and the position of the machining starting point and the slope of the reference plane, and controls the movement of the main axis (102) etc. in such a manner that the tool (101) is made to travel more quickly than the tool (101) travel speed in the machining program, in a non-contact manner, when the tool (101) is positioned in a non-machining region.
