<p>[PROBLEMS] To provide a machine tool of which the operation rate can be increased by reducing the time for suspending an operation for machining an object to be machined during the object-machining operation using the machine tool. [MEANS FOR SOLVING THE PROBLEMS] In this machine tool apparatus (1), an object (8) to be machined is machined with a tool (3) by controlling the position of the object (8) held by a jigger relative to the tool (3). The jigger comprises at least a first jig (5) disposed at the position where the object (8) is to be machined, and a second jig (14) which is formed separately from the first jig (5) so as to be movable and by which the object (8) is detachably held. The first jig (5) and the second jig (14) have attaching/detaching means (17) for detachably mounting the second jig (14) onto the first jig (5).</p> |
