Abstract

PURPOSE:To reduce the capacity of a main memory by specifying the file to be loaded to the main memory from a submemory with a parameter and then loading only the file specified during application of a power supply into the main memory. CONSTITUTION:The file name which is loaded to a main memory 102c from a submemory device 101 during application of a power supply is stored to a parameter memory 102d of the main body 102 of an NC tape producing device in the form of a parameter. A power supply application signal PON is generated at a detecting part 104 with application of a power supply. With this signal PON a processor 102b reads the file name to be loaded to the memory 102c out of the memory 102d and supplies it to the device 101. The device 101 reads only the file coincident with the supplied file name out of a memory part 101b and sends it to the main body 102 via an interface circuit 103. Then this file is stored in the memory 102c.

Description

[Detailed description of the invention] The present invention relates to a method for automatically calling a specific file.

In particular, the present invention relates to a method for automatically recalling a specific file that can load only the minimum necessary files into a system storage device when the power is turned on.

For a system, after the power is turned on, data is necessarily stored in a storage medium (submemory) such as a magnetic tape, disk, floppy disk, or bubble memory.

It is not necessary to load all the files contained in the main memory into the main memory configured by semiconductor memory or the like.

However, in the conventional NC tape automatic creation system, the main memory has a capacity to store all the files, and after the power is turned on, all the files are stored in the main memory. This results in high main memory costs and long loading times.
) Ofc@ Accordingly, the present invention relates to a method for automatically calling a specific file, which does not require increasing the capacity of the main memory and can shorten the loading time.

The present invention will be explained in detail below.

Some automatic NC tape production systems can instantly produce NC tapes for lathes by simply pressing a key in accordance with instructions displayed on a graphic display screen. According to the automatic NC creation system, the following step is Step 9: inputting the quadrant (first to fourth quadrant) in which the design drawing is drawn.

←) Step of inputting the shape and dimensions of the assembly, (c) Step of inputting the material quality, (v) Step of inputting the machining shape and dimensions, (e) Step of specifying the machine origin and turret position, (to) A step for selecting processes such as center fir, drilling, outer diameter rough machining, inner diameter rough machining, outer diameter semi-finishing, inner diameter semi-finishing, outer diameter finishing, inner diameter finishing, grooving 9, thread cutting, etc. Step of selecting the tool by inputting the tool number and tool position compensation number, (G) Step of determining the machining range and cutting conditions, (S)
A step of calculating the tool path and creating NC data based on the data input in steps (a) to (g). A step of creating NC data (NC tape).

By the way, the cutting conditions in step (a) are automatically determined if the material of the material has already been input. The cutting conditions include (a) clearance amount, (b) finishing allowance, (C) depth of cut, (d) return relief amount, (e) cutting speed, and (f) feed rate. In other words, there are files that specify cutting conditions for all materials such as iron, aluminum, and stainless steel. In other words, there are material files that specify cutting conditions for steel, material files that specify the next cutting conditions for aluminum, material files that specify cutting conditions for stainless steel, etc. do.

Now, in such a case, you can easily create only the NC data for processing the aluminum material.
Except for the aluminum material file, other material files do not need to be stored in the main memory of the automatic NC tape creation device, and can be recalled from the sub-memory each time they are needed.

In this way, if you only need to store the minimum necessary files in main memory without storing all files in main memory, you can reduce the main memory capacity and shorten the initial loading time. .

FIG. 1 is a block diagram of an NC tape production system which is an embodiment of the present invention. 101 is a sub-memory device in which a plurality of files (Fl, F2,...Fn) necessary for NO tape creation are stored; 102 is the main body of the NC tape creation device having a combiner configuration; , processing device 102b.

It has a main memory 102C and a parameter memory 102d. Various parameters are stored in the parameter memory 102d. For example, when the power is turned on, a file name to be Vcoded from the sub memory 101 to the main memory 102c (or a file name that does not need to be loaded) is stored as a parameter. has been done.

103 is an interface circuit that controls data transfer between the submemory 1 (11) and the NC tape creation device main body 102;
04 is a power-on detection unit that detects power-on and outputs a power-on signal PON, and 105 is an external storage medium such as a paper tape or magnetic tape for recording created NC data.

Next, the operation of the present invention will be explained according to the flowchart shown in FIG.

When the power is turned on, the power-on detection section 104 generates a power-on signal PUN. When a power-on signal is generated, the processing device 102d stores the sub memory 10 under the control of the control program.
Recall the file from 1. That is, the processing device 102
b reads the file name of the file that needs to be loaded from the parameter memory 102d, sends it to the interface circuit 103, and stores it in the sub-memory device 1o1 (
7t (for example, a magnetic tape device or magnetic disk device). In addition to this, the read/write circuit 101a built in the sub-memory device 101 is connected to the NC tape creation device main body 1.
Only the files matching the file name sent from 02 are sequentially read from the memory unit 101b, sent to the main body 102 via the interface circuit 103, and stored in the main memory 102C.

And reading and output of all files and main memory 10
When the storage process to the 2C is completed, it becomes NC tape creation standby.

As described above, according to the present invention, there is no need to store all files in the main memory (main storage device), and only the minimum necessary files need to be stored, so the capacity of the main storage device can be reduced, and the file Initial loading time was reduced.
