Abstract

PURPOSE:To originate NC data that can be put into an NC program by producing the command code by originating an NC auxiliary command code in the form of the NC data when an input signal produced by a manual operation is stored in a correspondence table storing the NC auxiliary command codes. CONSTITUTION:A teaching function is selected to originate and store the manual operation contents as an NC program, and an input signal DI is inputted to the NC side from an operation room 22 via the switch input. A processor 11 refers to a table (TB) 13 to judge whether an M code corresponding to the signal ID is stored in the TB 13 or not. If so, the reserved instruction added to the M code is judged. If this reserved instruction is equal to a REG, the M code is added to the NC program as the NC data. While only the execution is carried out if the reserved instruction is equal to an EXE. Furthermore the M code is originated and executed repetitively if the reserved instruction is equal to an EXEREG respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an NC data creation method, and particularly to an NC data creation method that can create specific manual operation contents as an NC auxiliary command code.

<Prior art> A numerical control device (NC'l) executes a predetermined numerical control process based on an I"JC program to move a machine moving part such as a tool or table to machine a workpiece as instructed. Also, the NC device is used for jobs.

The tool can be positioned at the desired position by manual feed operation of the handle, etc., or by one block of NC data (MDI command) from the MD cutting device, or moved along the desired cutting path to perform machining. It has become.

By the way, people who are not good at programming or people who are used to manual operation may perform machining by manual operation without creating an NC program, and if it is the first time to process a workpiece, try machining it by manual operation while making detailed settings. In some cases, after trial machining, an NC program is created and machining is performed.

<Problem to be solved by the invention> However, in the past, even if the desired machining was performed by manually moving the tool relative to the workpiece, the manual operation command could not be saved as NC data, so the same workpiece could not be processed. In order to obtain it, manual operations must be repeated each time.
Alternatively, a new NC program must be created based on trial machining, which poses a problem of inefficiency.

For this reason, the applicant has filed an application for an NC data creation method (filing date: 63.s, ao, name: NC data creation method) that incorporates the content related to feeding among manual operations and creates a passage. . However, the NC data includes not only path data but also machining auxiliary data such as forward/reverse rotation of the main shaft, turning on/off of coolant, etc., and it is necessary to easily insert these machining auxiliary data into appropriate locations.

From the foregoing, it is an object of the present invention to provide an NC data creation method in which, when processed manually, specific manual operation contents can be stored in a built-in memory as an NC program (part program).

Another object of the present invention is to provide an NC data creation method that can create a predetermined NC auxiliary code (for example, an M code) and insert it into an NC program when a high-voltage switch on the machine side is operated. be.

Means for Solving the Problems> The above problems are: (1) storing an NC auxiliary command code corresponding to a specific input signal indicating manual operation content in a correspondence table; and storing an input signal due to the manual operation in the correspondence table. If so, this is achieved by a step of creating an NC auxiliary command code corresponding to the input signal as NC data.

Function> The NC auxiliary command code corresponding to a specific input signal indicating the manual operation content of the machine side operation panel is stored in the correspondence table, and when the input signal due to manual operation is stored in the correspondence table, An NC auxiliary command code corresponding to the input signal is created as NC data. <Embodiment> FIG. 1 is a block diagram of an NG device to which the present invention can be applied, where 11 is a processor, and 12 is a program that stores a control program.

This is a machine side control panel with buttons. Note that data corresponding to M function commands, etc. is output from the NC side to the machine side via the digital output terminal (00 terminal) of the interface 18, and from the machine side to the NC side, data is output via the digital output terminal (00 terminal) of the interface 18.
Data (switch on/off data) is input through 8 predetermined digital input terminals (DI terminals).

The display w15a has various dialogue screens.

Soft keys are displayed, and the operator can input predetermined data interactively with the system while referring to the dialog screen. The state shown in Figure 1 is an interactive screen in which the teaching function (NC data creation function by manual operation) that creates and stores manual operation contents as an NC program is selected, and some NC data is created and displayed by manual feed operation. It is.

FIG. 2 is an explanatory view of the main parts of the machine side operation panel, in which 22a is a main shaft forward rotation switch that rotates the main shaft in the normal direction, 22b is a main shaft reverse switch that reverses the main shaft, 22c is a main shaft stop switch,
22d is a cutting oil on switch for supplying lubricating oil during cutting, and 22e is a cutting oil off switch for stopping the supply of lubricating oil.

The on/off signals for these switches are 1 e.g.

The on/off signal of the main shaft forward rotation switch 22a is sent to the first OI terminal ITI of the interface 18, and the on/off signal of the main shaft reverse rotation switch 22b is sent to the second DI terminal DI.
T2, the on/off signal of the spindle stop switch 22c is 3
Connect the th DI terminal DIT3 to the cutting oil on switch 22d.
The on/off signal of the cutting oil off switch 22e is sent to the fourth 01 terminal DIT4, and the on/off signal of the cutting oil off switch 22e is sent to the fifth DI
In the teaching mode, NC data is created based on the manual operation details ε inputted to the NC side via terminals DIT5.

When the NC device receives the ON signal of each of the switches, it creates and executes predetermined NC data (M code).

FIG. 3 is an example of a teaching function definition screen showing the contents of the correspondence table TB stored in the RAM 13 according to the present invention.

Switch on/off signal (input signal) DI input from the machine tool 21 to the NC side via the interface 18
correspond to the M code, which is the NC auxiliary command code on the NC side, respectively, and the main shaft normal rotation switch 2 in Fig. 3
2a (DITI) turns on signal, Mo3 turns on, spindle reverse switch 22b (["11T2) turns on signal, Mo4 turns on, spindle stop switch 22c (DIT3
), the MOS turns on the cutting oil on switch 22.
It is assumed that Mo2 is created by the ON signal of the cutting oil off switch 22e (DIT4), and MOS is created by the ON signal of the cutting oil off switch 22e (DIT5). At this time, the correspondence table TB contains zero terminals ([) tTl, DIT2 . ...) and NC accordingly.
An auxiliary command code (M code) is stored in advance.

If, for example, the main shaft forward rotation switch 22a on the operation panel is pressed during the teaching mode, the DI terminal DIT
The ON signal is taken into the NC device via I, the M code corresponding to it is read from the correspondence table TB, and the M code (M2S in this case) is created as NC data.

As mentioned above, the correspondence table TB stores the function (M code) for the input signal DI, but in addition to the M code, reservations are also made as to whether or not to create the M code and/or to execute the M code. Manual signal for command (DI terminal number)
If an input signal DI by manual operation is stored in the correspondence table TB in correspondence with the input signal DI, an M code is created and executed according to the reserved command corresponding to the input signal DI. can be made to do so.

For example, reservation commands EXEREG (execution & registration), EXE (execution), REG + registration) are added following the M code such as Mo3 (normal spindle rotation). And EX
For example, when a signal with EREG added is generated,
When the main spindle normal rotation switch 22a is pressed, the main spindle normal rotation operation is executed and M code Mo3 is created as NC data. Further, when a signal to which EXE is added is generated, for example, when the main shaft reversal switch 22b is pressed, the main shaft reversal operation is executed without creating the 1M code MO4 as NC data.

Furthermore, when a signal to which REG is added is generated.

For example, when the cutting oil on switch 22d is pressed.

The M code MO7 is only created as NC data, and cutting oil is not actually supplied.

Normally, execution and registration is sufficient, but by remembering a reserved command that only performs registration or execution.

(i) In the case of registration only, when it is difficult to actually operate the machine or when only the NC data needs to be changed, the NC data can be created by manual operation without actually operating the machine. In addition, (...) In the case of execution only, if the operation is a trial operation and no actual program is required.1 If you want to operate the machine only by manual operation, you can only execute it without creating NC data. conduct.

By creating the correspondence table TB by distinguishing between execution and registration, execution only, and registration only, it is possible to specify in detail the M code for creating NC data.

FIG. 4 is a flowchart of the process of the present invention. Hereinafter, the NC data creation process will be explained according to the flowchart shown in FIG.

First, select the teaching function that creates and stores manual operation contents as an NC program (step 101).
Input signal DI is NG by switch input from operation panel 22
(step 102).

The processor 11 refers to the correspondence table TB (step 103) and determines whether the M code corresponding to the input signal D1 is stored in the correspondence table TB (step 1).
04) If there is no memory, return to step 102 and repeat the subsequent processing.

If the memory exists, the reserved command added to the M code is determined (step 105).

If the reserved instruction is rREGJ, the M code is added to the NC program as NC data (step 106), and if the reserved instruction is rEXEJ, only execution is performed (step 10).
7) If the reserved instruction is r EXEREG J, create an M code and execute it (step 108);
Returning to step 102, the subsequent processing is repeated.

<Effects of the Invention> According to the present invention, the NC auxiliary command code corresponding to a specific input signal indicating the content of 1 manual operation is stored in a correspondence table, and the input signal resulting from 1 manual operation is stored in the correspondence table. In this case, since the NC auxiliary command code corresponding to the input signal is created as NC data, specific manual scratching contents can be stored in the built-in memory as an NC program (part program).

Further, along with the NC auxiliary command code, a reservation command as to whether or not to create the NC auxiliary command code and/or whether to execute the NC auxiliary command code is stored in a correspondence table in correspondence with the input signal, When an input signal generated by manual operation is stored in the correspondence table, the NC auxiliary command code is created and its execution process is performed according to the reserved command corresponding to the input signal. Codes can be specified in detail.
