Abstract
A control device calculates a specified quantile in stored data relating to a load applied on a spindle, as a target spindle load, and controls a feed speed of the spindle as to a work, so that the measured load applied on the spindle is the calculated target spindle load. A user can set the target spindle load with the load on the spindle measured in a state in which the work is being stably machined as a reference.
Claims5
A control device that adjusts a feed speed on the basis of a load applied on a spindle when machining a work, the control device comprising:
- a spindle load storage unit that stores data relating to the load applied on the spindle;
- a quantile specifying unit that specifies a predetermined quantile;
- a target spindle load calculating unit that calculates the quantile specified by the quantile specifying unit, in the data relating to the load applied on the spindle stored in the spindle load storage unit, as a target spindle load;
- a spindle load measuring unit that measures the load applied on the spindle;
- and
- a control unit that controls the feed speed of the spindle as to the work, so that the load applied on the spindle is the target spindle load.
