[Industrial application field]

The present invention relates to a machining condition setting device for a machine tool that sets and outputs optimal machining conditions for the machine tool.

In recent years, machine tool processing factories are required to process a wide variety of shapes and materials, and the types of machine tools used are increasing.

However, in order to perform processing with these machine tools,
An operator who is familiar with each machine tool is required to set the machine tool conditions, and it is extremely difficult for anyone other than the operator to set the conditions.

Under the above circumstances, there is a need for a machining condition setting device for a machine tool that allows a person other than the operator to set conditions.

[Conventional technology]

A conventional method of setting conditions for machine tools will be explained.

Conventional machine tool conditions are set based on the long experience, know-how, or knowledge of operators who are familiar with each machine tool.

In recent years, machine tool processing factories are required to process a wide variety of shapes and materials, and as the number of types of machine tools used has increased, the number of operators who are familiar with each machine tool has decreased. There is a growing tendency to do so.

[Problem to be solved by the invention]

The machine tool condition settings in the conventional machine tool condition setting method explained above are performed based on the long experience, know-how, or knowledge of operators who are familiar with each machine tool. As the number of machine tools increases, there is a tendency for the number of operators who are familiar with each machine tool to decrease, leading to the problem that there will be no successors for the operators.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide a machining condition setting device for a machine tool that allows even a person other than the operator to easily and easily set machining conditions for a machine tool.

[Means to solve the problem]

As shown in FIG. 1, the machine tool machining condition setting device of the present invention includes a condition input section 1 for inputting input conditions, a registered condition storage section 2 for storing registered conditions, and a condition input section 1 for inputting input conditions. A verification unit 3 compares the input conditions with the registration conditions stored in the registration condition storage unit 2, and compares the input conditions with the registration conditions in the registration condition storage unit 2 that are similar to the input conditions, and determines whether the input conditions are appropriate. Optimal condition inference that calculates possible machining conditions, corrects these machining conditions based on information obtained from the test machining results of the workpiece, obtains optimal conditions, and registers these optimal conditions in the registered condition storage unit 2. 4.

[Effect]

That is, in the present invention, as shown in FIG. 1, input conditions are input to the condition input section 1 and 1. The input condition input into the condition input section 1 is compared with the registration condition stored in the registration condition storage section 2 in the collation section 3, and if the input condition matches the registration condition, this input condition is displayed on the display section 5. Then, the machine tool starts operating under these input conditions.

In the unlikely event that the input conditions do not match the registered conditions, the optimal condition inference unit 4 compares the input conditions with the registered conditions in the registration condition storage unit 2 that are similar to the input conditions, and selects processing conditions that are considered appropriate. The calculated conditions are calculated and test machining is performed on the workpiece, the machining conditions are corrected based on the information obtained from the test machining results, the optimal conditions are determined, and the optimal conditions are registered in the registration condition storage unit 2. Display section 5 for optimal conditions
is displayed, and the machine tool starts operating under these optimal conditions.

In this way, the optimal conditions are determined and the machine tool is operated under these optimal conditions, and at the same time, these optimal conditions are registered in the registered condition storage section 2, so it is possible to accumulate the machining conditions of the machine tool. , the probability that the registered conditions match the input conditions during the verification in the verification section 3 is increased when setting the conditions of the machine tool thereafter, and even a person who is not familiar with the machine tool can easily set the conditions of the machine tool. becomes possible.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG. 2, with reference to a YAG laser processing machine.

As shown in FIG. 2, first, processing conditions are input into a condition input section 1, for example, a keyboard of a personal computer, in response to an inquiry from a computer database. For YAG laser processing machines, the type of processing method (
(drilling or welding), the material of the workpiece, and the following processing conditions.

■Applied voltage ■Focal length of lens ■Focal shift amount ■Irradiation pulse width ■Number of irradiation pulses ■Number of repetitions per second In the collation unit 3, this input condition and the registered condition storage unit 2 are stored in, for example, a computer database. The registered condition, for example, is checked against all records in the database, and if the condition is already registered, this registered condition is displayed on the display unit 5, for example, a computer display, and the YAG laser processing machine is operated with this registered condition. Start.

If it is determined that the input condition is not registered in the registration condition storage section 2 through the verification in the verification section 3, the classification section 4a of the optimal condition inference section 4 first determines whether the material of the workpiece is selected from among the input conditions. For example, if the processing method is welding, it is determined whether welding is possible or not. If processing is not possible, it is displayed on the display section 5 and the operation is stopped.

If the classification unit 4a determines that machining is possible, the calculation unit 4b determines whether the machining conditions are within the capability of this processing machine, and if it is outside the range, the display unit 5 and stop the operation.

If the calculation unit 4b determines that it is within the machining capacity range, it compares the input conditions with the registered conditions in the registered condition storage unit 2 that are similar to this input condition, calculates machining conditions that are considered appropriate, and sets these machining conditions. is displayed on the display section 5 and test machining is performed.

Based on information obtained from the workpiece test-machined under the test machining conditions, the test machining conditions displayed on the display section 5, for example, are modified in the modifying section 4c using a keyboard. For example, in the case of welding, if a hole is formed in one of the workpieces and welding becomes impossible, the value of the applied voltage is reduced.

In this way, the optimal machining conditions are found, and the registration section 4d assigns a name to the optimal machining conditions in response to an inquiry from the computer database, and registers them in the registration condition storage section 2.

In this way, the collation unit 3 compares the registered conditions in the registered condition storage unit 2 with the input conditions, and in the case of new input conditions, determines whether the material of the workpiece can be processed and whether the processing method can be implemented. It is determined whether the processing conditions are within the capability of this processing machine.

If it is within the machining capability range, the input conditions are compared with similar registered conditions in the registered condition storage section 2 to calculate machining conditions that are considered appropriate, and test machining is performed under these test machining conditions.

The machining conditions are corrected based on information obtained from the test-machined workpiece to find the optimal machining conditions, a name is given to the optimal machining conditions, and the optimal machining conditions are registered in the registered condition storage section 2.

Although this embodiment has been explained in the case of a YAG laser processing machine, the present invention is not limited to the YAG laser processing machine, and in the case of other machine tools, the database record can be used for that machine tool. It can be applied to all machine tools by changing the machining conditions.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the input conditions are compared with registered conditions in the collation section, the input conditions are classified in the classification section, the processing conditions are calculated in the calculation section, and the processing conditions are determined in the correction section. Since the registration section registers the optimum machining conditions in the registered condition storage section, subsequent optimum machining conditions can be stored in the registered condition storage section. It is possible to provide a machining condition setting device for a machine tool, which has the advantage of being able to easily make decisions and can be expected to have significant economical and reliability improvements.
