JPS62264848A - Nc program creation device for self-cut of pawl - Google Patents

Abstract

PURPOSE:To attempt the automatic creation of NC program by providing a device computing a working range based on data for a work start point, a self-cut diameter, and a length, a CL data preparation device, and a device which performs the conversion into an NC format followed by transfer. CONSTITUTION:Data inputs consisting of data for work start points SX and SZ when a tool is actually moved to the work start points, working diameters D1 and D2, the length JL of a pawl, and the length L of raw materials. Then these data are inputted into a working data preparation device 2 for preparing data based on SX, SZ, D1, D2, JL and L applicable to a raw pawl (a) for a part and a row pawl (b) for a rework. Subsequently, tool locus data are prepared by a CL data preparation device 3. And then said data are transformed into an NC format by an NC data conversion/transfer device 4 for sending them to a memory 5 at the NC side. As the aforementioned method is not for the input of a form working, an NC program is automatically created.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an NC program creation device for pawl self-cutting in an automatic programming device for an NC lathe.

<Prior art> For self-cutting of raw nails using an NC lathe, there is no dedicated automatic programming device, and the operator has to perform the self-cutting directly by operating the machine or create the NC tape by himself/herself.

<Problems to be solved by the invention> In order to chuck a wide variety of material shapes, green jaws are constantly self-carting, and the shape of the green jaws themselves is not constant. If you try to create a program for self-cutting nails, you will have to perform a series of inputs, such as measuring and inputting the shape of the raw nail before processing, and then inputting the shape after processing. It was more advantageous to operate the machine and perform the self-cutting of the nails. However, in the case of manual machining, the machining diameter (in the axial direction) due to the thickness of the jaws is always constant, so it was not possible to machine back-tapered shapes as would be the case with ordinary lathes.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the present invention aims to provide an NC program creation device for a nail self-cart that creates NC data by automatic programming for self-cutting of raw nails.

Means for Solving the Problems〉 The present invention achieves the above-mentioned objects by using an input screen that includes the machining start point, which is the position in the machine coordinate system when the tool is moved, the self-cut diameter, and its length. A machining area data creation device that calculates a machining area from the data, a CL data creation device that creates CL data based on the machining area data using the cutting conditions on the input screen, and a CL data creation device that converts the CL data into an NC data format. It is characterized by having an NC data conversion and transfer device for transferring data to a memory.

Function> By calculating the area to be machined from the machining start point and self-cut diameter and length data, and taking into account the cutting conditions, NC can be performed using a conventional automatic programming system.
Data can now be created.

EMBODIMENTS> The present invention will now be described in detail with reference to FIGS. 1 to 4. In FIG. 1, 1 is data input, and this data input is "1" on the input screen shown in FIG.
．． Processing section: Consists of nail self-cutting data up to the length of the nail material. This data is not the input data of the machining shape, but includes the machining start point, which is the position in the machine coordinate system when the tool is actually moved to the machining start point, the self-cut diameter, and the self-cut length. However, as shown in the input screen shown in FIG. 3 and the simulated wind in FIG. 2, it consists of machining start point data sx, sz, machining diameter 01°02, nail length JL, and material length L.

Data input 1 is input to the machining area data creation device 2 shown in FIG. Let's take a look at the above-mentioned "1. Processing section...
・7. Create data for the area to be shaved from the data up to the length of the nail material. That is, for the new raw nail (a) and the reworked raw nail (b) shown in FIG. 2, machining start point data sx, sz, machining diameter 01. [12, length JL,
Processing area data, which is the shaded area, is created from the relative dimensional difference of L. In this case, among the element shapes surrounding the diagonally shaded part, the thick line part becomes the processed shape data, and the other parts become the material shape data.

Based on the machining area data, the CL data creation device 3
Cutting conditions shown in Fig. 3 "8. Tool registration number...12.
The tool path data (CL: cutter location) is created by "cutting depth".

The NC data conversion and transfer device 4 converts the CL data into an NG rough format and sends the created NC data to the memory 5 on the NC side. In this case, "13. Program No. J" on the input screen shown in FIG. 3 is used.

FIG. 4 shows an output example of the NC data thus created.

<Effects of the Invention> As explained above, according to the present invention, instead of inputting the machining shape, the tool is actually moved to the machining start point and the position in the machine coordinate system at this time is input as the machining start point. Also, since you can input the diameter and length of the self-cut, you can now automatically create a program for self-cutting your nails, which used to be a troublesome task.
The functions of the automatic programming device will be expanded.
