Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a processing data supply device to an automatic NC programming device, and in particular, the present invention relates to a processing data supply device for an automatic NC programming device, and in particular,
The present invention relates to a machining data supply device that supplies new machining data to a capable NC automatic programming device.

(Prior Art) Conventionally, NC automatic programming devices have been used to create control programs for NC machine tools. Furthermore, in recent years, data linkage between the NC automatic programming device and a drawing/drafting device (CAD) has become increasingly common.

FIG. 3 is a diagram schematically showing a system from the drafting device to creating a control program for the NC machine tool.

The processed data generated by the drafting/drawing device 1 is temporarily stored in a processed data storage medium 2 such as a floppy disk.

The pressure data stored in the processing data storage medium 2 is NC
It is input into the automatic programming device 3, translated into a format suitable for the control program of the NC machine tool, and then written on the NC tape 4.
It is expressed by punching etc. The NC tape 4 is N
It is read by the reading device of the C machine tool, and the NC machine tool is automatically driven according to the control program.

FIG. 4 shows a conceptual diagram of the drafting device 1 constructed using CAD. In the conventional drafting device 1, when cutting a plate-shaped object, for example, a cutter path (tool trajectory) 6 is determined by the cutter bus information generating means 1a, and this is transferred to the shell file IC. The processed data was transferred to storage medium 2. Note that 1b in the figure shows a display section.

In addition, when making a box-shaped object as shown in Fig. 5(a), as shown in Fig. 5(b), place an appropriate diameter and a A drill with a deep blade is applied, rotated and inserted to an appropriate depth, and then moved along a cutter bus as indicated by the dotted line in the figure. In this example, the cutter path indicated by the dotted line is the pressure data in the file lc1. :r'6 and was transferred to the pressurization data storage means 2.

(Problems to be Solved by the Invention) In recent years, the NC automatic programming device 3 has been improved and has become closer to a drafting device, and graphic display and editing on the screen have become H1 functions.

When attempting to modify or change machining data using the NC automatic programming device 3, contour information that is the basis of the tool trajectory and machining attribute information that defines the machining process etc. are required. Since only the cutter bus data was supplied to the NC automatic programming device 3, the contour information was generated from the cutter bus data. However, as is clear from the example shown in FIG. 5, this task is extremely difficult.

Furthermore, there is a problem in that the user has to input the machining attribute data once again into the NC automatic programming device 3.

Therefore, in the conventional system, there was a problem in that it was difficult to effectively utilize the editing functions and the like of the NC automatic programming device.

The purpose of the present invention is to eliminate the problems of the conventional device described above,
It is an object of the present invention to provide a machining data supply device capable of supplying machining data suitable for an NC automatic programming device having f=i functions such as screen display and editing of figures.

(Means and operations for solving the problems) In order to achieve the above object, the present invention is an addition to an automatic NC programming device. It is characterized by the provision of information generation means.

According to the present invention, new machining data consisting of cutter bus information, machining attribute information, and contour information can be supplied to the NC automatic programming device, so that editing such as corrections and changes to machining drawings can be performed in the NC automatic programming device. This can be automatically programmed.

Therefore, it can be expected that the degree of freedom of operation will be increased for the user, and that it will be very convenient.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic diagram of an embodiment of a drafting apparatus according to the present invention. In this embodiment, an additional attribute information generation means 11 and a contour information generation means 12 are added to the cutter bus generation means 1a of the conventional drafting and drawing apparatus.

From the cutter bus generation means 1a, cutter bus data 6 can be input as in the conventional case, and from the pressurization attribute information generation means 11, processing information such as hole drilling position data, type of tool to be used, and its size, etc. Attribute data 13 is entered manually. For example, data such as the position to drill a hole at (xO, yO) and the use of a drill with a radius of 5 mm is entered manually.

Further, the contour information generation means 12 manually generates contour data 14 of the wave-processed object.

When inputting the cutter bus data 6, machining attribute data 13 and contour data 140 is completed, these data are stored in a file l.
c, 15 and 1G. Next, the new processing data creation means 17 creates it in a predetermined format and sends it to the pressurization data storage means 2.

The newly added data stored in the processed data storage means 2 is then sent to the NC automatic programming device, which has functions such as graphic screen display and editing.

In the NC automatic programming device, the cutter locus, the outline of the workpiece, the type of tool to be used, the procedure for using the same, etc. are displayed on the display section as necessary. Therefore, if the user wants to change the cutter trajectory, such as jJ5 a,
When it is desired to change the PJI of the tool to be used or the machining procedure, the change can be made manually in the NC automatic programming device.

Next, the structure of the newly processed data created by the new data creating means 17 will be explained with reference to FIG.

The new processing data is composed of the following elements (1) to (15).

(1) Processed data header section The data identification name, generation date 11, etc. are written in the processed data header section.

(I4) Processing attribute information end section The processing attribute information end declaration is written in the processing data end section.

(15) Processed data end section In the processed data end section, a declaration of the end of processed data is written.

Note that when there are a plurality of processing drawings, the elements (2) to (14) are repeatedly provided after the above (14) for each processing drawing.

The processed data with the above configuration is stored in the processed data storage medium 2.
HNc
The cutter bus, contour and addition-1 attribute data are displayed on the NC automatic programming device display.

Therefore, when the user wants to change the machining drawing or edit the repair iF, etc., the user performs the editing work while looking at the display section and performs the automatic programming operation, so that the edited machining drawing can be automatically programmed. .

(Effects of the Invention) As described above, according to the present invention, in addition to conventional cutter bus information, machining attribute information and contour information are created by a drafting device, and this is fed to the NC automatic programming device. Therefore, with the NC automatic programming device,
While looking at the machining drawing displayed on the display section, it is possible to edit the machining drawing by making changes, corrections, etc., and automatically programming the edited machining drawing. Therefore, it is very convenient for users to create control programs for NC machine tools.
