US 5,155,425 A · NC data execution method

Abstract

An NC data execution method which permits an efficient checking of the validity/invalidity of NC data through a simple operation. In an NC data execution process, a processor of an automatic programming apparatus reads out NC data, block by block, from a memory (S2), and determines whether or not the read NC data block satisfies an NC data execution interrupt condition, e.g., whether or not the data block contains a specific code (S3). When the interrupt condition is fulfilled, the data block is displayed at an input display field on the screen (S4), and then the NC data execution, including a graphic display operation based on the content of the data block satisfying the interrupt condition, e.g., a display of a tool path and the reading and display of the next block, is automatically interrupted, whereby the operator is allowed to thoroughly check the data block satisfying the interrupt condition. After the data checking, the NC data execution is restarted upon input of an interrupt disable command through the operator's key operation (S5-S7).

Dependent claims

An NC data execution method performed with an automatic programming apparatus, comprising the steps of:

(a) presetting an interrupt condition in the automatic programming apparatus;
(b) reading out NC data, block by block, with the automatic programming apparatus and successively displaying the NC data for machining and a tool path for machining that would be created by execution of said NC data on a display sceen;
(c) determining whether or not each block of the NC data satisfies the interrupt condition, each time each block of the NC data is read out and displayed;
(d) determining whether or not an interrupt disable command is input to the automatic programming apparatus;
and
(e) interrupting the execution of the NC data by the automatic programming apparatus upon determination in said step (c) that the interrupt condition is fulfilled, until input of the interrupt disable command is detected by the automatic programming apparatus.
