Abstract:
1. A method for controlling a tool selecting operation in a turret tool rest including a turret provided with a plurality of tool-mount portions at respective indexing angles in a circumferential direction, in which a rotating tool fitted to a certain tool-mount portion rotates in a passive manner in accordance with a turning indexing motion of said turret, said method comprising: selecting whether a phase of a rotating motion of said rotating tool, fitted to said tool-mount portion of said turret, is adjusted to be identical each time said rotating tool is disposed at an indexed position; causing said turret to perform a turning indexing motion, when it is selected that said phase of said rotating motion of said rotating tool is adjusted to be identical, in such a manner that a cumulative sum of said turning indexing motion of said turret in a same turning direction is less than one rotation; and causing said turret to perform a turning indexing motion, when it is selected that said phase of said rotating motion of said rotating tool is not adjusted to be identical, in such a manner that an individual turning indexing motion of said turret is at most half a rotation in any turning direction.
