Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an NC (numerical control) machine tool, and more particularly to an NC machine tool having functions such as failure diagnosis and testing, and education and explanation to customers.

[0002]

2. Description of the Related Art Conventionally, this type of NC machine tool has a function of storing, as operation procedure data, an input by an operation key operated by an operator who operates an equipment section having a drive axis and reading and reproducing it. However, it does not have the function of re-editing the operation procedure data to modify the program and perform the desired operation by the NC machine tool.

For example, in Japanese Laid-Open Patent Publication No. 1-311303, the operation procedure input by the operator is stored together with the input time, and when a failure of the NC machine tool occurs,
A technique for reproducing the operation procedure including time and analyzing an operation history leading to a defect is described.

[0004]

In the above-mentioned conventional NC machine tool, a program is created by editing the operating procedure for controlling each equipment section, but since it does not have a function of performing a desired operation, Even with a slight change in operation, the operator must re-enter the operating procedure from the beginning while operating the NC machine tool.

Therefore, there is a drawback in that the work efficiency is deteriorated in re-inputting due to an operator's input error of an operation key, checking of input data, creation of operation procedure data, and the like.

[0006]

According to the present invention, a drive unit having one or a plurality of drive shafts, a drive unit for controlling the operation of the drive unit, an operation command and an operation confirmation for the drive unit. An operation control unit for performing the operation, an instruction input unit for inputting an instruction, a storage unit for storing the input operation instruction as operation procedure data, and an editing unit for editing the operation procedure data according to an instruction from the instruction input unit. I have it.

Further, the driving means transmits the operation command and its response to the driving equipment section, and the operation command and the operation confirmation to the equipment section based on the operation command via the input / output means. And input / output control means for performing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The NC machine tool of the present invention has a drive unit 1 having a drive shaft, a drive unit 2 for controlling the operation of the drive unit 1, and a control software built-in to the drive unit 2 and an operation command and its confirmation. An operation control unit 3 for performing an operation, an instruction input unit 4 for inputting an instruction, a file storage device 5 for storing the input operation instruction as operation procedure data in an operation procedure file 5a, and an operation procedure file according to an instruction from the instruction input unit 4. And a file editing unit 6 for editing the operation procedure data stored in 5a.

FIG. 2 is a block diagram showing details of the drive device section 1 and the drive means 2 of FIG. In the figure, the drive device section 1 is composed of drive devices 1a to 1n having one or a plurality of drive shafts (in this embodiment, a case where n drive devices are provided is shown). Further, the driving means 2 is based on the input / output unit 21 which is connected to each of the driving devices 1a to 1n and transmits the operation command and its response, and the information sent from the operation control unit 3 via the input / output unit 21. Drive device 1
The input / output control unit 22 controls the operations a to 1n.

Next, the operation of the NC machine tool of the present invention will be described in detail.

Normally, in order to perform each operation in the NC machine tool, first, the operator inputs / outputs corresponding to the driving devices 1a to 1n through the instruction input section 4, the operation control section 3 and the input / output section 21. The operator confirms the operating state of each of the driving devices 1a to 1n by instructing the section 21 to perform input / output operation one by one. In the NC machine tool of the present invention, the operator operates from the instruction input section 4 One input / output operation is stored, and if specified, it is saved as an operation procedure file 5a, or necessary operation procedure data is read from another operation procedure file 5a already saved and executed. Alternatively, the operation procedure data is edited again by the file editing unit 6 and executed.

That is, first, in accordance with an instruction from the instruction input unit 4, the driving device 1a is passed through the operation control unit 3 and the driving means 2.
When the operation control unit 3 is instructed to store the content of the operation to be performed thereafter, when the operation is performed by driving the drive device 1b and detecting the drive state by the drive device 1b, the operator operates the drive device 1a. The contents of the performed operation instruction input are generated as predetermined operation procedure data by the built-in control software, and the operation procedure file 5a is saved by the file storage device 5.

Next, in order to perform the operation of detecting the drive state by the drive device 1b, the operation instruction input made by the operator is similarly stored in the operation procedure file 5a. When the input of the operation to be stored is completed, the operator instructs the operation control unit 3 so as not to store the operation content of the operator thereafter. As a result, the procedure for driving the driving device 1a and detecting the driving state of the driving device 1a by the driving device 1b is stored.

Then, the operation procedure data saved in the operation procedure file 5a is saved as it is, is saved after being modified, is executed without saving, or another operation procedure file 5a is read. An operation such as post-correction or execution is performed. For example, in the case of saving, the stored operation procedure is saved as the operation procedure file 5a by the file storage device 5 as it is.

Here, when the operation of the drive equipment section 1 is executed, the operation procedure file 5a is stored in the file storage device 5.
The operation procedure data stored in 1 is read one by one and input from the file editing unit 6 to the operation control unit 3. The operation control unit 3 outputs necessary operation commands by the built-in control software, and drives the drive devices 1a to 1n via the input / output control unit 22 and the input / output unit 21 which are the driving means 2.

When changing the contents of an existing operation procedure file or creating a new operation procedure file, the contents of the operation procedure file 5a are read out by the file storage device 5 and based on the operation procedure data. An operator performs editing work by the file editing means 6 via the instruction input unit 4. Then, it is saved as an operation procedure file with a different name or the same name.

[0018]

As described above, the NC machine tool of the present invention has a function of saving the key input made by the operator for controlling each drive device as an operation procedure file and reproducing it, and has an operation procedure. Since it has a function to edit the contents of the file and create a program, if necessary,
It is possible to read the operation procedure file and reproduce the operation procedure desired to operate.

Furthermore, once the operation procedure file is created, the same check operation can be executed for a plurality of NC machine tools, which has the effect of improving the check work efficiency.

When the NC machine tool is to be operated differently, it is not necessary for the operator to input the operation procedure while operating the NC machine tool, and the stored operation procedure file is modified and executed. There is an effect that it can be easily realized only by.
