The present invention relates to a finishing surface roughness setting method for numerically controlled processing machines (hereinafter referred to as NC processing machines). NC processing machines control the position of the tool relative to the workpiece using corresponding numerical information to process the workpiece. According to NC processing machines, it is possible to easily and efficiently machine objects with complex shapes. It can be processed with precision and productivity can be further improved. In NC machining machines, it is necessary to set the finished surface roughness in advance prior to machining, and setting the finished surface roughness is important. However, conventional NC machining machines have had the problem that setting the finished surface roughness is complicated.
In other words, in conventional NC processing machines, in order to obtain the finished surface roughness specified in the instructions, the operator calculates the spindle feed rate and spindle rotation speed through complex calculations, and calculates the values numerically. Since input was made using keys, and the setting of the finished surface roughness was done off-line at the actual processing site, there was a drawback that setting the finished surface roughness was complicated. The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a finished surface roughness setting method for an NC processing machine that can automatically set the finished surface roughness. In order to achieve the above object, the present invention includes a display that displays menus of a plurality of types of finished surface roughness in several columns on the screen, and a plurality of key switches provided corresponding to the menus. When a desired surface roughness is selected and specified from multiple types of surface roughness displayed on the display screen by operating a corresponding key switch, the processing necessary to obtain the desired surface roughness is displayed. The tool feed amount per spindle rotation of the machining tool, which is a condition, is automatically calculated from the selected finished surface roughness and the nose radius of the machining tool, and the desired finished surface roughness can be automatically set. It is characterized by what it can do. Hereinafter, preferred embodiments of the present invention will be described based on the drawings. FIG. 1 shows the configuration of an operation board according to an embodiment of the present invention. In FIG. 1, the operation board 10 is provided with a CRT 12 as a display.
The screen is configured to display, for example, 24 rows and 80 columns of characters. Furthermore, at the bottom of the screen of the CRT 12, menus 14-1, 14-2,...,
Menu display section 1 that displays 14-9 in several columns
4 is reserved. Also, at the bottom of the CRT 12, the menus 14-1, 14-2,...,

The state displayed on the screen is shown. Here, the menus 14-1,..., 14-9 in FIG.
is determined with reference to the surface roughness code, surface roughness (μ), and triangular signal in Table 1. In addition, Table 1 is
This is the case of every transfer (meaning the tool feed per rotation of the spindle), and the surface roughness code is the case of no grinding undercut.

点を有する。[Table] Further, the operation board 10 is provided with a data setting key group 20, and desired data is inputted using the data setting key group 20. Next, a method for setting the finished surface roughness will be explained based on the flowchart of FIG. 3, FIGS. 1 and 2. When setting the surface roughness, when entering the machining program, the surface roughness menu (Figure 2) will automatically appear on the CRT screen when you enter the surface roughness data. will be displayed. That is, as shown in FIG.
1,..., 14-9 are displayed. The operator selects a desired finished surface roughness from a plurality of types of finished surface roughness on the screen, and operates a key switch corresponding to a menu of the desired finished surface roughness. For example, "▽2"
If , the key switch 16-2 corresponding to the menu 14-2 is operated.
As a result, the feed rate and rotational speed of the main spindle of the processing machine to obtain a desired finished surface roughness, for example "▽2", are automatically determined through predetermined arithmetic processing of the numerical control device. As described above, according to the embodiment of the present invention, the feed rate and spindle rotation speed of the main spindle of the processing machine to obtain the desired finished surface roughness are automatically determined.
Desired surface roughness can be automatically set. Next, a predetermined arithmetic processing method for determining the feed rate and rotational speed of the main spindle of the processing machine will be explained. Figure 4 shows the finished surface of the workpiece, where H: Finished surface roughness (mm) F: Each transfer (mm) (referring to the tool feed per spindle rotation) r : Tool nose R (mm) Then, there is a relationship between H, F, and r as follows: H=F 2 /8r...(1). Therefore, according to equation (1) above,
Since the nose r of the tool is known, by specifying the finished surface roughness H, the transfer rate F, that is, the feed rate of the main spindle, can be determined each time. Note that it is assumed that the spindle rotation speed is predetermined. Through the above calculation processing, the feed rate and rotational speed of the main spindle of the processing machine to obtain the desired finished surface roughness are determined. As explained above, according to the present invention, the processing conditions of the processing machine to obtain the desired finished surface roughness, such as the spindle feed rate and spindle rotation speed, are automatically determined, so that the desired finished surface roughness can be obtained. The degree can be set automatically. Therefore, it has the advantage that the finished surface roughness can be easily set online.
