Claims

[Claims for Utility Model Registration] A device for creating NC data for a machine tool that performs three-dimensional machining of a workpiece according to a tool path using a rotary tool, comprising: the material of the workpiece, the type, diameter, and number of teeth of the rotary tool; A standard machining conditions database that stores a relationship table between a combination of main factors consisting of the following, and a standard machining condition consisting of the spindle rotation speed S and feed rate F determined by the combination; A machining condition change rule base that stores change coefficients for changing the standard machining conditions in combination with sub-factors that cause the conditions to be changed in a rule format in which each factor is a condition and the change coefficient is a conclusion; and the main factor. standard processing condition determining means for searching the standard processing condition database based on the values of and determining standard processing conditions; determining success or failure of each rule of the processing condition change rule base from the values of the main factor and the subfactor;
a machining condition changing means that determines a change coefficient from the conclusion of the established rule and changes the standard machining conditions with the change coefficient; and NC data according to the machining conditions changed by the machining condition change means and the tool path. An NC data generation device comprising: NC data generation means for generating .
