PROBLEM TO BE SOLVED: To provide a control device for controlling a machine tool having a function automatically changing a cutting condition.SOLUTION: A control device 10 of a machine tool carrying out work machining according to a machining program, includes: tool cutting condition setting means 11 which sets an upper limit value and a lower limit value of each of rotation speed, feeding speed, and a cutting load of a tool used for machining; change condition setting means 12 which sets a range and a change condition for changing at least one of the rotation speed and the feeding speed of the tool in the machining program; load calculating means 13 which calculates a load during cutting from the change amount of a cutting condition before changing the machining program and a cutting condition of the changed machining program; and determining means 14 which determines whether at least one of the changed feeding speed, rotation speed, and the calculated cutting load is within the range of the upper limit value and the lower limit value of each of the rotation speed, the feeding speed, and the cutting load set by the tool cutting condition setting means.SELECTED DRAWING: Figure 9 |
