PROBLEM TO BE SOLVED: To provide a machine tool cutting condition optimization device and a machine tool cutting condition optimization method with which a load can be fixed, and machining time can be shortened.SOLUTION: The machine tool cutting condition optimization device optimizes a cutting condition of the machine tool. The machine tool cutting condition optimization device comprises: an NC program optimization function part which performs such a change that a setting value of a feed rate is made slower at a portion where predicted cutting resistance is larger, and the setting value of the feed rate is made faster at a portion where predicted cutting resistance is smaller, on the basis of a cutting condition and a tool path designed by a CAM 12, and which performs segmentation of a control cycle, then changes the control cycle again and optimizes the cutting condition, for a portion where it is determined that NC control cannot follow the change of a machining shape, on the basis of an actual tool path, a feed rate, and a load value in trial machining performed on the basis of the cutting condition including the setting value of the changed feed rate and the tool path; and a storage part for storing the actual tool path, feed rate, and load value in the trial machining. Thereby the load can be made fixed, and the machining time can be shortened. |
