Abstract

PURPOSE:To attain the effective numerical control of a machine tool by storing first a series of key operations for operation as a working program and repeating these key operations in a single key operation. CONSTITUTION:When keys are operated on a control board 1 after a switch 6 is turned on, the key codes are sent to an input key analyzer 3 and also stored in a key code buffer memory 7. When the switch 6 is turned off, a key code converter 8 converts the key codes stored in the memory 7 into a format 10 by the input codes, etc. This format 10 is stored in a memory 2 in the form of a working program. This working program is analyzed by a working program device 4 and at the same time a machine controller 5 delivers the control data according to the analyzing result of the device 4. Thus it is possible to make a machine tool perform the same function with all key operations.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a numerical control device that operates a machine tool according to analysis results of a machining program registered in a memory.

[Conventional technology]

Figure 2 is a block connection diagram of a conventional numerical control device.
In the figure, ■ is an operation board that manually inputs commands and data, 2 is a memory that registers machining programs, 3 is an input key analysis means that analyzes the contents of commands from input keys on the operation board 1, and 4 is a machining program. The analysis means and 5 are machine control means.

Next, the operation will be explained. A signal input by the operation board l is analyzed by the input key analysis means 3.

For example, if this is an operation in which a machining program in the memory 2 is called up and operated, the machining program in the memory 2 is analyzed by the machining program analysis means 4, and its contents are sent to the machine control means 5.

In this case, for example, if a format 10 as shown in FIG. 3(b) is stored in the memory 2 in advance, the machining program analysis means 4 analyzes this and stores keys from key 1 to key n. It is possible to input the same data to the machine control means 5 as when the operation board 1 is operated by a person in order, and in this case, the formant 10 as described above can be executed in the same way as the processing program. The symbols must be converted into symbols corresponding to each key and stored in the memory 2 in advance.

Note that this conversion into symbol form is performed using a symbol correspondence table as shown in FIG. 3 (al).

(Problems to be solved by the invention) Since the conventional numerical control device was configured as described above, all key operations had to be performed by a person. There were problems such as the need to create a format 10 as shown in FIG. 3 and store it in the memory 2 in advance so as to incorporate it into the program.

This invention was made to solve the above-mentioned problems, and it stores key operations for any period of time, converts the stored series of key operations into a predetermined format, and converts it into a numerical value that can be stored in memory. The purpose is to obtain a control device.

[Means for solving problems]

The numerical control device according to the present invention stores all key operations performed when operating a machine tool in the 11 means,
This series of stored key operations is converted into a format similar to the machining program by a key code conversion means and stored in a memory, and the format based on the key operations stored in this memory is analyzed and the machine control means This allows control to be executed by

[Effect]

The storage means in this invention stores a series of key operations during a predetermined period and can convert the stored key operations into a machining program, so that if the machine tool is operated according to this machining program, for example, a single To save the trouble of repeatedly performing the above series of key operations by only key operations.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 6 is a key operation memory on/off switch that is closed when storing key operations, and 7 is this switch 6.
8 is a key code converting means for converting the key code stored in the key code buffer memory 7 into the format of a machining program.

Note that other blocks that are the same as those shown in FIG. 2 are designated by the same reference numerals, and redundant explanation thereof will be omitted.

Next, the operation will be explained.

First, when storing key operations, switch 6 is turned on. Thereafter, when a key operation is performed on the operation board 1, the key code is sent to the input key analysis means 3 and stored in the key code buffer memory 7 via the switch 6.

On the other hand, when the switch 6 is turned off, the key code conversion means 8 converts the key code stored in the key code buffer memory 7 into one block at the delimiter of a certain operation, such as the code for "input", as shown in FIG. Convert to format IO as shown.The above key code buffer memory 7
After converting all the key codes stored in the above into the format 10, this is stored in the memory 2 as one processing program. Next, the machining program created in this way is analyzed by the machining program analysis means 4, and
According to the result, the machine control means 5 outputs control data, and operates so that a specific key operation causes the machine tool to perform the same function as the entire series of key operations.

In the above embodiment, the switch 6 was used only to turn on/off the operation of the key code buffer memory 7 and the key code converting means 8, but the key code buffer memory 7, the key code converting means 8, and the input key analyzing means 3 It can also be used as a switch to change between In this case,
When a key operation is memorized, the input key analysis means is in an off state, so that it does not operate in accordance with the operation. As a result, key operations can be stored without changing the current operating state.

〔Effect of the invention〕

As described above, according to the present invention, key operations for an arbitrary period of time can be stored and the stored key operations can be converted into a machining program, so that when the same key operation is repeated many times, By first memorizing a series of key operations and running this as a machining program, you can avoid repeating the same key operations.
This has the effect of allowing the machine tool to automatically perform the same actions one after another as if a series of key operations were performed.
