Abstract

PURPOSE:To simplify an external measuring instrument by providing a storage part for storing size set on a setting display part and a skip signal generation part which generates a skip signal when externally supplied measurement data coincides with size stored in the storage part. CONSTITUTION:Size data on the generation of a skip signal is stored in the storage part of an NC device 1 and the set size is compared with measurement data sent from the measuring instrument by the skip signal generation part to generate the skip signal internally. Numerals of sizes 11-13 where the skip signal 5 is generated are set in the setting display part 14 previously and stored in the storage part 15. Then, a working program 2 is decoded by a command control part 6 in order to carry on operation and the skip signal generation part 17 monitors the relation between data 16 sent from the measuring instrument 4 successively with the size 11 stored in the storage part 15 previously during the working of, for example,a worked part 8 of a work 7 and then generates the skip signal 5 immediately when the size of the worked part 8 satisfies the generation condition of the skip signal. Consequently, the measuring instrument provided outside the NC device is simplified.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a numerical control device (hereinafter referred to as an NC device) that internally generates a skip signal.

[Conventional technology]

This is a measuring device for generating a skip signal 5 according to the following conditions, and includes a measuring section 4a, a setting section 4b, and a skip signal generating section 4C. Reference numeral 6 denotes a command control unit that issues commands to the controlled object 3 based on the relationship between the cannibal program 2 and the skip signal 5.

Further, FIG. 2 shows an example of the workpiece 7, and 8, 9.10 are the dimensions corresponding to the machined parts, and 11, 12, and 13 are the dimensions corresponding to the machined parts 8°, 9.10, respectively.

Next, the operation will be explained. It is assumed that the NC device 1 continues to operate sequentially based on the information in the cannibal program 2, and is operating a block in the cannibal program 2 that requires a skip operation. It is also assumed that the machined part 8 of the workpiece 7 in FIG. 2 is being machined at this time. The machining state is measured by a measuring device 4, and when the machining progresses and the dimension reaches the preset dimension 11, the measuring device 4 sends a skip signal 5 to the NC device 1.

When the command control section 6 of the NC device 1 receives the skip signal 5 from the measuring device 4, it immediately interrupts the currently running block and starts running the next block. Similarly below,
The machining of the machining parts 9 and 10 of the workpiece 7 is also continued by generating the skip signal 5 with the corresponding dimensions 12 and 13, respectively.

[Means for solving problems]

The NC device according to the present invention stores a dimension for which a skip signal is to be generated in a storage section inside the NC device using a setting display section, and also generates a skip signal by comparing the set dimension with measurement data sent from a measuring device. Perform at the site of occurrence,
This allows the skip signal to be generated internally.

[Effect]

The skip signal generating section in this invention compares the dimension set by the setting display section with measurement data from the measuring device, and generates a skip signal when the measurement data matches the set dimension.
