Abstract

An interactive numerical control apparatus is programmed by inputting data through keys on a control panel, and answering questions displayed on a display screen, to generate a numerical control program. The operator defines a blank shape and a part shape (steps S1, S2), and selects a primary machining operation or a secondary machining operation (step S3). A cutting region for the primary machining operation is defined in the same manner as with an ordinary two-axis lathe. For the secondary machining operation, the blank and part shapes are displayed in reverse (step S6), and a cutting region for the secondary machining operation is defined in the same manner as the cutting region for the primary machining operation is defined (step S7). Based on the necessary data and machining conditions that are defined, the interactive numerical control apparatus outputs numerical control data separately for the respective primary and secondary machining operations (step S8).
