Abstract

PURPOSE:To omit the labor and the time needed for production of a new working program by using a material different from the reference material based on which the working program is produced, inputting the quality of the material through a quality input picture, and producing the working program based on the material quality and the shape of the parts for working of a product. CONSTITUTION:A quality input picture concerning a material is selected and displayed on a CRT 16 among the program input picture of a numerical controller. Then the material of a reference material 1a that is already inputted to an item of the material quality is changed as necessary into the quality of a new material. Thus a new working program is automatically produced within the numerical controller based on the new material quality and the parts shape of a product. Then the product is worked based on the new working program. Thus it is possible to omit the labor and the time needed for production of a new working program.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for processing the same product using a numerical control device (CNC).

[Conventional technology]

FIGS. 4(a) and 4(b) are diagrams showing the program manual screen in the numerical control device. Items necessary for initial settings, such as items related to materials, are entered on the program input screen 7. The items in step (01) are entered on the program manual screen 8. For example, when bar material machining is selected, by inputting the machining area, the tool number and cutting conditions (peripheral speed, feed rate, depth of cut) are automatically determined and displayed.

In this way, with an interactive numerical control device, you can create a machining program by inputting the necessary data from the program input screen (usually multiple screens) in response to a request from the numerical control device. You can easily create machining programs without any special knowledge.

The product was processed using the processing program created in this way.

[Problem to be solved by the invention]

However, in the processing program of the conventional numerical control device,
Even when creating the same product, if the material is different, a new Progera is created, so it was necessary to re-enter not only the new material but also other data from the Progera input screen.

At the site where products are processed, there are cases where the missing product is made up of by using other materials due to processing errors, defective materials, delayed delivery of materials, etc. In such emergencies, new Creating a bulletin board was very tedious.

The present invention has been made in view of these points, and it is possible to manually enter the material properties of different materials from the base material from the material input screen related to the material on the manual screen, generate Kanibrograd, and produce the product. The purpose of this invention is to provide a processing method for a numerical control device for processing.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a numerical control device (
CNC) which processes products from different materials
In the machining method, a material of a different material from the standard material for which the machining program was created is used, the material of the material is input from a material input screen, and a Kanibrograd is generated from the abrasive material and the part shape of the product, A CNC processing method is provided for processing a product.

[Effect]

A material input screen related to the material among the program input screens of the numerical control device is displayed on the CRT. If necessary, change the material of Group 1 that has already been input into the material field to a new material to be used.

A new machining program is automatically generated in the numerical control device based on the new material and the part shape of the product, and the product is machined using the new machining program.

〔Example〕

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

FIG. 2(a) is a diagram showing a state in which a product is processed from a reference material using a lathe. In the figure, the reference material 1a is a reference material. The figure shows a cross section of the upper half of the material 1a.

The material 1a is fixed to a spindle (not shown) by a spiral chuck 3. The cutting area 2 shown in the shaded area is cut by a tip 5 fixed to the tip of a cutting tool 4 according to a processing program of a numerical control device. The machining path in this case is shown by 6a. If the feed amount is RFa, the chip 5 is fed while cutting by RFa per spindle rotation. If the depth of cut is MDa, the chip 5 is prime +,
Cut t 1 a with a depth of cut of MDa.

Although not shown, the circumferential speed of the lathe is stopped at Sa. These feed rate 1RFa, depth of cut ffiMDa, and circumferential speed Sa are cutting conditions for the reference material.

FIG. 2(b) is a diagram showing the state of processing a product from a non-standard material using a lathe. In the figure, lb is a material different from the reference material. The figure shows a cross section of the upper half of the material 1b. A material 1b different from the standard is fixed to a spindle (not shown) by a chuck 3. The cutting area 2 shown in the shaded area is cut by the chip 5 fixed to the tip of the cutting tool 4 using a new processing progera l, which is a numerical control device. The machining path in this case is indicated by 6b and -C.

If the feed amount is RFb, the chip 5 is fed while cutting by RFb per spindle rotation. If the depth of cut is different from MDb, the tip 5 cuts the material 1b with the depth of cut MDb. Although not shown, these cutting conditions in which the peripheral speed of the lathe is sb are different from the standard material, so the feed rate is RFa-RFb, the depth of cut is MDa-MDb, and the peripheral speed is Sa→ It has been changed to sb.

FIG. 4(a) is a program input screen of the numerical control device, and is the same diagram as that described in C. Prior Art. The program input screen 7 has input items for manually inputting data necessary for the machining program.
