ABSTRACT:
In a machine tool controller (1): a position control unit (12) controls, based on an operational signal input from without during manual operation, a moving body's move-to point and moving speed; a memory (13) stores data modeling the moving body and any potentially interfering machine-tool structure; a travel-area checking unit (17) defines in the modeled structure speed-control regions obtained by displacing the structure's contour, generates, based on the defined speed control regions and on current moving-body position, data modeling the moving body as moved into its current position, to check whether the moving body will travel within a speed control region, and if so, sends to the position control unit a speed limit predefined for that speed control region. The position control unit controls the moving body to travel at speed limit if the operational-signal-directed moving speed exceeds the speed limit.
