<p>A method of checking a machining program for a numerical controller of an NC lathe having a plurality of tools mounted on the turret, by which interferences between tools and the work, and between the tools and each part of the lathe can be detected before the machining. In the stage of writing a machining program or of its simulation, all the tools n which are defined to be mounted on the turret A are detected (S1 to S4, and S6 to S8); the positional relationship between the tool m to be used and the other tools n is found (S5 and S9); the current positions of the tools n are found (S10) in accordance with the positional relationship and the machining program defined for the tool m to be used; and whether or not each of the tools n interferes with the work B or the area of the chuck C is judged in order to provide an alarm display (S11 to S14). Hence any interference of tools can be checked before the machining.</p> |
