Abstract

PURPOSE:To shorten the signal input time to a machine tool by dividing the command signals which set many working conditions into two groups according to their using frequencies and having input of signals of higher using frequencies via a keyboard with codes set for each signal and input of signals of lower using frequencies as the sound signals respectively. CONSTITUTION:A question is given for the conditions to be set in synthetic voices through a speaker 10c based on a prescribed program. The signals are supplied to a CPU 4 by the prescribed codes via a keyboard 10a with a command of a high using frequency. Then the propriety of these codes are decided based on a prescribed program and outputted through the speaker 10c. While the signals are supplied to the CPU via a microphone 10b and a voice identifying circuit with a command of a low using frequency. In such a way, the code signals or signals accordant with voices are sent to a setting means 7 and a processing device 8 is driven when the input is through with the proper set value. Thus even an unexperienced person can set easily input of the working conditions. Then the signal input time is shortened to a machine tool.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for inputting signals to a machine tool, for example, dividing various machining conditions input into a control device such as a wire-cut electrical discharge machining device into two groups. The present invention relates to a method for inputting command signals using a keyboard or voice depending on the frequency of use.

[Conventional technology]

When machining is performed using a wire-cut electrical discharge machining device, the material and quality of the target workpiece, the reference position of the workpiece, the material and electrode diameter of the wire electrode, the discharge voltage, the discharge current, or the pulse width of the discharge current, and It is necessary to set the rest time, the amplitude of the discharge current, and the injection pressure of the machining fluid to appropriate values.

If each of the above setting values is set to an appropriate value, machining can be performed efficiently and the workpiece can be machined well, but if the setting values are not input properly, Alternatively, if the set value is inputted incorrectly, the machining process takes time and it becomes difficult to perform good machining on the workpiece.

In particular, conventional wire-cut electrical discharge machining equipment was configured to set machining conditions by operating multiple setting knobs provided on a panel, etc., so each time machining conditions were set, There was a problem that it was inconvenient to have to operate it by hand when going to the place. In addition, in order to proceed with machining more efficiently and to perform good machining on the workpiece, there are an extremely large number of setting items for machining conditions, so even experienced workers may forget the items that should be set. In some cases, the settings were not made properly, or even the settings were entered incorrectly.

In addition, when a beginner operates a wire-cut electrical discharge machining device, he or she usually operates each switch and operating lever of the device while reading the manual or instruction manual. It was extremely difficult to operate properly.

In order to solve the above problems, the applicant of the present application
No. 1-038977 and Japanese Unexamined Patent Publication No. 61-041494 disclose a method of inputting processing conditions and the like using audio signals.

When using the above method, the processing conditions can be set by voice, so not only experienced users but also inexperienced users can easily set the processing conditions. In No. 041494, the items to be set are asked in sequence, and each time a question is answered, the setting values are confirmed using a synthesized voice.
After that, the process of setting the machining conditions will proceed, so you can avoid forgetting setting items, not inputting the setting values properly, or even inputting the setting values incorrectly. It was possible to perform good processing on the material.

However, setting numerical values among the machining conditions that need to be set in wire-cut electric discharge machining does not require special encoding, so it is better to input the numerical values directly with a keyboard etc. than to input them by voice. is efficient, and some of the conditions to be set are always set to approximately constant values regardless of the material of the workpiece, the shape of the workpiece, etc., so all setting items can be set by voice during machining. If the process of sequentially inputting and checking the set values each time is repeated, there is a problem in that it takes too much time to input all the processing conditions to be set.

[Problems to be solved by the present invention]

The present invention has been made based on the above-mentioned viewpoints, and its purpose is to set machining conditions in machine tools such as wire-cut electrical discharge machining equipment, and to enable not only experienced but also inexperienced people to set machining conditions. It is an object of the present invention to provide a method for inputting signals to a machine tool, which can be easily performed even by a person skilled in the art, and also allows setting of various machining conditions in a short time and reliably.

[Means for solving problems]

The above purpose is to divide the command signals to be input into two groups depending on how frequently they are used, to determine a code for each command signal that is used frequently, and to input that code via the keyboard. Inputs that are used less frequently are achieved by inputting them as audio signals.

[For production]

By configuring as described above, machining conditions can be easily set by not only experienced people but also inexperienced people, and each machining condition can be set in a short time. Since the process can be performed reliably, processing time can be significantly reduced compared to conventional equipment.

〔Example〕

Hereinafter, details of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing the circuit configuration of a device for implementing the signal input method for a machine tool according to the present invention;
FIG. 2 is a code input flowchart, and FIG. 3 is an audio signal input flowchart, and FIG. 4 is an explanatory diagram showing another embodiment.

First, the explanation will be given with reference to FIG.

In Figure 1, 1 is a microphone, 2 is an amplifier, 3 is a voice recognition circuit, 4 is a CPU, 5 is a voice generator, 6 is a speaker,
7 is a setting device, 8 is a wire-cut electrical discharge machining device, and 9 is a keyboard.

Therefore, in the wire-cut electrical discharge machining apparatus, it is necessary to set each machining condition to an appropriate value before starting machining.

In the present invention, the command signals to be input are divided into two groups depending on the frequency of use, and for command signals that are used frequently, a code is determined for each command signal, and the code is inputted via the keyboard 9. On the other hand, input the ones that are used less frequently.
Setting values and the like are input via a microphone 1 as an audio signal.

Then, before starting processing, the CPU 4 requests processing conditions and other settings to be set for each item sequentially in the form of a question using a synthesized voice from the speaker 6 via the voice generator 5 according to a predetermined program.

That is, for example, at the beginning, "What is the material of the workpiece?
", "What is the program number?", "What is the diameter of the wire electrode?" For each command signal with a high value, a code is determined in advance for each command signal, so the code is inputted via the keyboard 9.

The code signal input via the keyboard 9 is input to the CPU 4, and the code signal is input to the CPU 4.
determines whether the code is compatible with a predetermined program, and if it is not compatible with the program, the same question is asked again. In addition, if the program is compatible, the CPU 4 stores the setting value based on the above code in the setting device 7, and each time the setting value is stored in the setting device 7, the CPU 4 operates the audio generator 5. Then, a signal tone indicating the completion of the setting is generated via the speaker 6.

On the other hand, items that are used less frequently, that is, items that must be set only when special processing is performed, are input via the microphone 1 as an audio signal.

Therefore, when inputting a setting value using an audio signal, if there is no response to a question within a certain period of time, the same question is asked again, and the question is repeated a predetermined number of times, during which no response is received. If not, the operation will be stopped.

On the other hand, when the worker replies into the microphone 1, the voice signal input through the microphone 1 is amplified by the amplifier 2 and then input to the voice recognition circuit 3. Based on the voice signal input through the voice recognition circuit 3, it is determined whether or not the person who responded is actually the worker who is supposed to operate the device, and only in that case, the voice recognition circuit 3 transmits the voice signal through the microphone 1 and the amplifier 2. The reply input to the CPU 4 is inputted to the CPU 4.

Then, the CPU 4 determines whether the content of the reply is compatible with a predetermined program, and if it is not compatible with the program, the question is asked again. In addition, if the program is compatible, the CPU 4 operates the voice generator 5, repeats the content of the reply as a synthesized voice via the speaker 6, and tells the worker that the content of the reply is the one that the worker replied. Request confirmation whether it is the same as or not.

If the worker's answer is 'NOJ', the operator returns to the beginning and is again asked what the setting value should be for the machining conditions.If the answer is 'YESJ', CP' U4 is the setting device. 7, and the setting value inputted by the operator by voice is stored in the setting device 7.

As described above, when an appropriate setting value corresponding to one question is input by a code signal or an audio signal and stored in the setting device 7, the next question is sequentially performed, and all When an appropriate answer to the question is given and an appropriate setting value is input into the setting device 7, the setting device 7
The wire-cut electric discharge machining device 8 is driven based on the set values stored in , and wire-cut electric discharge machining is started.

Next, FIG. 4 will be explained.

In FIG. 4, the same numbers as those in FIG. 1 indicate the same components, and 10 is a keyboard that integrates a voice input device, a voice generator, a code input device, etc. It is.

Therefore, in this embodiment, a voice input device consisting of a microphone, a voice signal amplifier, and a voice identification circuit, a voice generation device consisting of a voice generator and a speaker, and a keyboard for inputting a code signal are integrally formed. It is something.

Thus, the code signal is input through the keys 10a, 10a, and the audio signal is input through the microphone 10b.
Then, the setting value input by the audio signal is transmitted to the speaker I.
The synthesized voice is repeated from the OC to confirm the input setting values. Therefore,
The entire device can be made smaller than the device shown in FIG.

That is, for example, in this embodiment, the machine tool is described as a wire-cut electrical discharge machining device, but it is not limited to the above-mentioned wire-cut electrical discharge machining device, and may be any known electrical discharge machining device, electrical machining device, etc. It can be used for machine tools. In addition, a voice recognition circuit is used as a circuit for analyzing and recognizing voice, and a synthesized voice is generated by a voice generator, but these are widely known if they can achieve the same effect. circuits and devices are available. In addition, although the setting value inputted by voice is configured to be repeated by synthesized voice to request confirmation, in addition to the above, it is also recommended to configure the setting value to be displayed as an illustration or the like on the display device.
