PROBLEM TO BE SOLVED: To provide a machine tool having an onboard measuring device that can make measurement precision and a machining time constant without relying on a worker's knowledge and skill concerning an operation of an onboard measuring system, and can achieve a stable production of a machined product having high form accuracy.SOLUTION: An accommodating device 24 accommodating an onboard measuring device 1 and provided with an automatic opening and closing cover 25, a washing liquid nozzle 30 injecting a washing liquid, a tool 32 and a cutting liquid nozzle 34 are disposed on a B axis, and a machining object 20 and a washing brush 22 are disposed on a C axis. A moving region of drive axes of a working machine is previously divided into a machining region (an effective machining range <1>), and a washing region (a range <2> belonging to neither the effective machining range nor an effective measuring range and the effective measuring range <3>). Positions of the drive axes are always monitored, and when the drive axes enter each of regions, work allocated to each of regions is automatically started and machining, cleaning and onboard measuring work are automatically performed by a numerical controller without any interposition of a worker so that the work is continuously carried out until the drive axes exit the region. |
