Abstract
A numerical controller for a machining center comprising a microprocessor connected to a data input device, a CRT display device and a data storage device. The microprocessor prepares an NC program for a workpiece to be machined, based upon machining information manually input by the use of the data input device and stored in the data storage device. The debugging of the prepared NC program is then executed, wherein the microprocessor obtains by calculation a workpiece interference space defined outwardly from the outer periphery of the workpiece, based upon workpiece blank shape and dimension data and workpiece mounting position data stored in the data storage device. The microprocessor further calculates, based upon the NC program, a tool path along which a tool spindle of the machining center would be moved relative to a work table in accordance with the NC program. The microprocessor ascertains based upon the tool path, a tool interference space, defined outwardly from the outer periphery of each tool, and the workpiece interference space, whether or not the tool interference space would enter the workpiece interference space in any rapid feed movement if relative movement betw…
