VERFAHREN ZUR AUSFÜHRUNG EINES BEARBEITUNGSPROGRAMMES

摘要

This invention relates to a method of continuous execution of NC programs for different types of machining, wherein parameter values are automatically changed in accordance with the types of machining such as rough machining, medium finish machining, and finish machining, memory in an NC apparatus stores parameters to be changed in accordance with the type of machining and their values, and the machining program in such a manner that they are associated with their corresponding types of machining. In the beginning of execution of each machining program, therefore, its associated type of machining is determined (steps S2 to S5), and the values of the parameters for the program are automatically changed in accordance with the type of machining (steps S7 to S9). In this way, a machining tool is controlled constantly with optimum parameters.
