Abstract
A method of generating machining conditions for a numerically controlled machine tool in which a machining is under proper machining conditions without altering the initial machining program even when it has become necessary to change the material of workpiece after completing a machining program. The method comprises the steps of dividing a function for determining machining conditions including a spindle rotational speed and a tool feed speed into a first part of the function independent of the material of a workpiece and a second part of the function dependent on the material of the workpiece. More specifically, when creating a machining program, only the first part of the function is retained in a storage medium as reference values for machining conditions together with the machining program, and, at the stage of executing the machining program, setting the second part of the function is set into a numerical control system by designating the material of the workpiece so that the first and the second parts of the function are synthesized to generate machining conditions.
