Abstract

A machining program execution method for an NC device, in which parameter values are automatically modified in accordance with the machining types in continuously executing machining operations of different machining types, such as rough machining, intermediate finish machining, finish machining, etc., by the NC device. A memory in the NC device is previously stored with the parameters to be modified in accordance with the machining types and the parameter values for each machining type, and machining programs and machining types are associated with each other and inputted to the NC device. At the start of execution of the individual machining programs, the machining types of the machining programs as objects of execution are discriminated by the designation of the machining type for the machining program and the parameter values are automatically modified in accordance with the machining type of the machining program. Thus, the machining operation of a machine tool can always be controlled by using optimum parameters.

Claims2

Dependent claims

A machining program execution method for an NC device, comprising the steps of:

(a) for a standard machining type, storing a set of values respectively corresponding to a set of parameters required for executing machining programs by an NC device in a first memory means in the NC device;
(b) for each of a plurality of non-standard machining types, determining a group of said set of parameters of said standard machining type which need to be modified in accordance with the non-standard machining type and modifying and storing a group of said set of values respectively corresponding to said group of parameters in accordance with the non-standard machining type, in a second memory means in the NC device;
(c) programming a parameter modification command for designating one of the plurality of non-standard machining types in the machining programs;
(d) reading said parameter modification command in said machining programs;
(e) automatically replacing the group of values in said set of values stored in said first memory means corresponding to said designated one non-standard machining type with said modified group of values stored in said second memory means corresponding to said designated one non-standard machining type, when said parameter modification command is read in said machining programs during an execution of the machining programs by the NC device;
and
(f) executing the machining programs by the NC device using the group of values replaced in said step (e).
