Abstract

PURPOSE:To simplify a survey and to produce a working program with high efficiency by using a prescribed operation key to call out a program command registered previously and then registering the command again. CONSTITUTION:When a teaching command button is turned on after an MDI mode is selected via a machine control panel 6, a display 42 is shown on a display device 2a of a CRT/MDI unit 2. Under such conditions, a teaching operation is carried out. Then a soft key 43 (TKMAC, conversation macro) when a registered command is required. Thus a display 41 already registered is shown. Thus the program command which is repetitively used in a teaching operation is previously registered in a buffer and then read out by depressing the key 43. When the program command is directly used in a teaching operation, the command is put into a working program by depressing a soft key 44 (INS, insertion). Consequently, the program command which is repetitively used can be simply instructed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a teaching method for creating a machining program using a numerical control device, and particularly to a teaching method that can easily issue program commands that are used repeatedly.

[Conventional technology]

There are numerically controlled machine tools that allow machining programs to be created by teaching.

In this teaching, we will create machining programs using MDI mode, handle mode, and jog mode.

That is, program commands such as the home return command, M command, and S command are taught using the MDI, and positioning and the like are taught using the jog mode and handle mode.

For example, when teaching drilling, the general positioning is performed in jog mode, the exact position of the hole is determined in handle mode, and the position is stored in a buffer within the numerical control device.

[Problem to be solved by the invention].

However, in general, similar program commands are used many times in teaching. For example, when machining with one tool is completed, the machine is always returned to its origin and the tool is replaced. Inputting such program commands each time from the MDI is time-consuming and may lead to teaching errors.

The present invention has been made in view of these points, and it is an object of the present invention to provide a teaching method that can easily issue program commands that are used repeatedly.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a teaching method using a numerical control device in which a machining program is created by manual operation or MDI (Manual Data Input). A teaching method is provided, which is characterized in that a machining program is created by calling the command program by operation and adding the command program to a buffer that stores a predetermined machining program.

[Effect]

Program commands that are used repeatedly are registered in advance.

Call this command using the operation keys when necessary,
In addition to the machining program, we will create a machining program.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 3 is a block diagram of a numerical control device for implementing the present invention. Channel bus 1 is a multi-master bus capable of coupling each channel. The channel bus 1 has a large number of slots 1a1, 1b, and 1g, and can connect channels, etc., which will be described later.

The CRT/MDI unit 2 displays the current position of each axis, the machining program, the shape of the workpiece, etc. on its display device 2a. Further, necessary data can be entered manually from the keyboard 2b. The axis control modules 3 and 4 can control two to three axes of servo motors with one module. The I10 circuit 5 sends and receives human output signals from the outside. Here, a mode signal (MDI,
(handle, jog) and teaching command signals. Note that in the figure, a PC (programmable controller) and the like are omitted.

Channels 10, 20 and 30 each have the functionality of one conventional numerical control device.

That is, one channel can process the reading, decoding, and execution of numerical control commands. Also, CRT/
It is also possible to control devices such as MDI units. Therefore, it is possible to process commands for a fixed number of axes, which conventional numerical control devices have processed, in individual channels.

For example, on a two-head numerically controlled machine tool, channel 1
10 controls the first main axis, Xl axis, Yl axis, etc., channel 20 controls the second main axis, X2 axis, Y2 axis, etc., and channel II [30 is used as a mask channel to monitor other channels. etc. can be executed as a whole.

Furthermore, channel 110 is connected to CR via channel bus 1.
Controls T/MDI unit 2.

These channels 10 to 30 are connected to the channel bus 1 and share the processing, and when the processing capacity of one channel is insufficient, part of the processing is transferred to another channel.

For example, if one channel 110 performs very fine interpolation and channel 20 performs linear interpolation, channel 20 may perform some of the preprocessing calculations for channel 110's interpolation. can. As a result, it is possible to ensure a balance in processing capacity so that there is no imbalance in processing.

Channel II [30, as a mask channel, performs overall control such as arbitration of the right to use channel bus 1 and monitoring of other channels. Of course, the channel 30 can also control the main axis or axes. Furthermore, when the number of tasks to be processed by channel 30 increases and it becomes impossible to execute overall control, and there is room in another channel, the masking right can be transferred to another channel.

FIG. 2 is a diagram showing an example of a display screen of the present invention.

When the MDI mode is selected on the machine operation panel 6 and the teaching command button is turned on, the display 42 is displayed on the display device 2a of the CRT/MDI unit 2.

When teaching is performed in this state and a registered command is needed, pressing the soft key 43 (TKMAC, dialogue macro) displays the already registered commands 41. This program command is a program command for returning to a reference point and exchanging tools. Program commands that are repeatedly used in such teaching are registered in a buffer in advance, and read out by pressing the soft key 43. If you want to use it as is for teaching, press soft key 44 (INS, insert) and it will be inserted into the machining program.

Further, if a part of the command is desired to be changed, the user presses the soft key 44 after changing the contents using the keyboard 2b including alphabets and numerical values of the CRT/MDI unit 2 (not shown). For example, if the soft key 44 is pressed after adding the next tool number to be replaced, the program command with the added tool number is added to the machining program.

Furthermore, if multiple commands are registered in the buffer,
Each time the soft key 43 is pressed, commands are displayed in the order of registration.

Furthermore, the display order can be such that program commands inserted into the previous machining program are displayed preferentially. this is,
Similar commands are useful when used consecutively.

For this purpose, the display priority may be increased each time a registered program command is inserted into a machining program.

Alternatively, the commands can be displayed in the order of frequently used commands. This can be done by storing the number of additions to the machining program in a non-volatile memory, arranging the program commands in descending order of the numerical value, and displaying them in that order.

Further, a program instruction can also be registered as including a plurality of blocks.

FIG. 1 is a flowchart of the processing of the teaching method of the present invention. In the figure, the number following S indicates the step number.

[S1] Frequently used program commands are registered in advance.

C82] Select in which mode teaching will be performed.

This is determined by the mode of machine operation number 6. That is, when the mode switch is MDI, the process proceeds to S3, when the mode switch is jogging, the process proceeds to S6, and when the mode switch is the steering wheel, the process proceeds to S7.

'[S3: Check whether a registered program command is required by teaching using IMDI, and if necessary, proceed to S4; otherwise, proceed to S5.

[S4] Since a registered program command is required, the registered program command is incorporated into the machining program using the soft keys 43 and 44 shown in FIG.

[S5] Registered program commands are not required, so
Using the operation keys of the CRT/MDI unit 2, normal commands are added to the machining program and teaching is performed.

[S6] Since the teaching is by jog operation, teaching is performed by moving each axis using the jog button.

[S7] Teaching is done by operating the handle.
Operate the handle to accurately position each axis for teaching.

[S8] Check whether the creation and editing of the machining program by teaching has been completed. If not, return to S2 and continue the process.

〔Effect of the invention〕

As explained above, in the present invention, during teaching to create a machining program, pre-registered program commands are called up and registered using predetermined operation keys, which simplifies the operation and allows efficient creation of machining programs. be able to.
