<p><P>PROBLEM TO BE SOLVED: To provide a machining system accurately machining even if a workpiece bends. <P>SOLUTION: The machining system 1 includes: a lathe 10 including end supporting mechanisms 13 and 15 for horizontally supporting both ends of a long workpiece W respectively, a tool rest 20 for holding a tool, a feed mechanism for moving the tool rest 20 in three orthogonal axial directions and a controller 25 for controlling the feed mechanism; and a non-contact measurement device 30 structured to be attached to/detached from the tool rest 20 and including a measuring head 31 for measuring, without contact, a distance from an outer peripheral surface of the workpiece W rotated at rotation speed during machining in a plurality of positions in an axial direction of the workpiece W, and a deflection shape calculating part 54 for calculating a deflection shape of the workpiece W, based on the measured distance or the like. The controller 25 moves the tool along the deflection shape calculated by the deflection shape calculating part 54. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
