Abstract

A program code generating method for tilted plane machining makes the machine tool generate required program codes for machining a plurality of planes with various direction features. The method comprises: obtaining step of obtaining directional features of a first reference plane and a second reference plane; transformation step of obtaining coordinate transformations parameters between the directional features of the first reference plane and the second reference plane by coordinate transformations; testing step of making a tool shaft and a worktable of the machine tool perform a testing motion; and combining step of generating a combination code by adding the coordinate transformations parameters in the program codes applied to machining of the first reference plane, thereby making the machine tool subsequently perform machining on the second reference plane after performing machining on the first reference plane by using the combination code. A device for titled plane machining is also provided.
