Abstract

Abstract A method of correcting a machining program for a numerical control device during an execution of the program is provided. A created machining program, which is stored in a memory (5), is executed for a program check, a single block stop is effected at a portion (2) at which an error is found in the machining program, and the machining program is executed in reverse to a predetermined block (P1). Then the machining program is corrected and executed. Accordingly, it is not necessary to return to the beginning of the machining program for a reexecution thereof, and thus the machining program can be efficiently corrected.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 79 words
A method of correcting a machining program for a numerical control device during an execution of the machining program, said method comprising the steps of: a) executing a created machining program for a program check; b) effecting a single block stop at a portion in the machining program at which an error is discovered in the machining program; c) executing the machining program in reverse to a predetermined block; and d) correcting the machining program and then executing same.
Claim 2
Independent Claim 79 words
A method of correcting a machining program for a numerical control device during an execution of the machining program, said method comprising the steps of: a) executing a created machining program for a program check; b) effecting a single block stop at a portion in the machining program at which an error is discovered in the machining program; c) executing the machining program in reverse to a predetermined block; and d) correcting the machining program and then executing same.
Claim 3
Dependent Claim 25 words
A method according to claim 1, wherein the reverse execution of the machining program is effected by a reverse switch provided on an operator panel.
Claim 4
Dependent Claim 49 words
A method according to claim 1, further comprising a substep of storing movement data in an auxiliary memory during the execution of the machining program for a program check, and effecting the reverse execution of the machining program in accordance with the movement data stored in the auxiliary memory.
Claim 5
Dependent Claim 28 words
A method according to claim 1, wherein the execution of the machining program for a program check is effected in a dry run mode without using a workpiece.
Claim 6
Dependent Claim 33 words
A method according to claim 1, wherein the execution of the machining program for a program check is effected by displaying a workpiece and a tool on a display screen by graphic animation.
