Abstract

PURPOSE:To improve the interchangeability between processing programs and then the productivity by providing a table memory where the codes in an NC (numerical control) information are put opposite to each other among types of devices, a retrieval processing circuit, etc. to convert the NC machining information. CONSTITUTION:Machine tools A and B perform the machining jobs by means of the drilling machines of the same series according to the NC programs recorded to perforated tapes C1 and C2. Here the tool B has a high working speed and can not use directly the tape C1 of the tool A. Therefore the tape C1 is applied to a converter D and converted into the NC machining information that is applicable to the tool B. In this respect, the converter D contains an input device 1, a table memory 2, a coefficient memory 3 and a retrieval processing circuit 4, an arithmetic processing circuit 5, a CPU8, etc. The NC machining information is shifted in the order of a list. When an area requiring a change is detected, a converting process is carried out through each processing circuit with reference to each corresponding memory.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the invention (a) Industrial application field The present invention relates to a processing information converter necessary for operating an NC machine tool, and in particular, to a predetermined model with holes punched in a paper tape. This invention relates to an NC machining information converter that makes machining information compatible with that of another model.

(b) Conventional technology In general, NC machine tools are controlled based on machining information recorded on hole punch tapes, etc. However, as technology advances, when a factory introduces a new model, even if the same type Even if you purchase a machine from the same manufacturer for processing work, for example, the spindle drive method may have changed from AC to DC direct, the drive speed may have increased, or the control itself may have changed slightly. In many cases, the processing information of the previous model cannot be used as is. However, as in recent years,
As the speed of technological innovation accelerates, several models may be introduced and coexist within a factory before the previous model is retired, and it is extremely inconvenient if processing information is not at least compatible between similar models. become.

(B) Problems to be Solved by the Invention In view of the above-mentioned circumstances, an object of the present invention is to provide a converter that can make the NC processing information of a desired model compatible with the NC processing information of another desired model. Our goal is to provide a converter for N'C machining information that increases the compatibility of machining programs between NC machine tools, rationalizes the factory, and improves productivity.

(2) Structure of the Invention (a) Means for Solving the Problem In order to achieve this object, the present invention provides that the part that requires conversion in the NC processing information is divided into a code part and a numerical part. Focusing on the fact that it can be classified into , NC processing information is converted by providing a table memory and its search processing circuit that make each code correspond to each model, and a coefficient memory and its arithmetic processing circuit that stores the conversion data of each numerical value. It is characterized by

(B) Examples Examples of the present invention will be described below in detail in G) based on the drawings.

FIG. 1 is a schematic configuration diagram showing the implementation status of the present invention.

In Figure 1, machine tool A and another machine tool B are drilling machines of the same series, and perform machining work based on the NC programs recorded on the perforation tapes CI and C2, respectively, to ensure compatibility of tools etc. However, since machine B is a newer machine with higher speed, it is not possible to use the perforation tape from another machine as is.
If there is a workpiece to be processed by machine B based on the program, the NC processing information on the perforated tape C1 is read by tape reader C, inputted to the exchanger described in this specification, and converted into NC processing information that can be used by machine B. Then, another chain hole tape C2
You can either create it or input it into machine B as is.

FIG. 2 is a block diagram showing an example of the internal configuration of an NC processing information converter embodying the present invention.

In FIG. 2, the converter includes an input means 1, a table memory 2, a coefficient memory 3, a search processing circuit 4, an arithmetic processing circuit 5, a tape puncher 6 as an output means, and a CR
The input means 1 is composed of a T-display 7 and a CPU (central processing unit) 8, and includes a tape reader 11 for reading the NC program from the chain hole tape, and a keyboard 12 for modifying the program or inputting a new one. There is.

The table memory 2 is a storage means for storing coded data of characters or numbers that can be made to correspond between different models, and is mainly related to machining data of a workpiece, which corresponds to the input NC program. When processing information is found, the CPU 8 executes the search processing circuit 4.
The corresponding index is found and replaced with the code of the desired model.

The coefficient memory 3 is a storage means for storing constants and function components for numerically modifying amounts that vary depending on the model, and mainly contains a lot of data on the control side, so that the corresponding machining information is not found in the input NC program. Then, the CPU 8 reads the constant from the memo 3 and converts it into a value for the desired model using the arithmetic processing circuit 5. The converted NC processing information is output to the tape puncher 6, and another perforated tape for a desired machine is created. The CRT display 7 displays desired data at each stage of the converter and serves as a monitor.

(c) Effect Next, the operation of the present invention will be explained.

FIG. 3 is a sample diagram showing an example in which the above-mentioned CRT display 7 compares and displays NC machining information of two different machines. In FIG. 3, the left side of the dashed line in the center of the screen displays machining information for machine A illustrated in FIG. 1, and the right side similarly displays machining information for machine B. Here, C56 or M7
1. G28, etc. are codes that indicate machine names, process instructions, subroutines, addresses of data addresses, etc., and the codes correspond to the table memory 2 shown in Figure 2, such as G51-G56 M71-MB2 G28XO → G30XO. The index is stored. In addition, S (a), F (1), etc. are function data that command the control amount of the machine, and although they differ from machine to machine in most cases, they can at least be corrected to approximate values for the desired machine. In order to do this, the coefficient memory 3 shown in Fig. 2 stores coefficients P1 and Ql as parameters that can be used to calculate S (b) = S (a) X, PI F (2) = F (1) x Q1. has been done.

The conversion procedure is that when the NC program shown in the left mold in Figure 3 is applied to the converter, the CP (J) transfers the NC processing information to the right mold in the order of the list, and the parts that require the above conversion are found. Then, the corresponding memory is referred to, each processing circuit performs conversion processing, and then the porting continues.

When the porting is completed for all columns of the list, N and C programs usable for machine B will be created, as shown on the right side of the screen in FIG.

(3) Effect of the invention As explained above, according to the present invention, N
The aim is to provide a converter that can interchange C machining information, increase compatibility of machining programs between NC machine tools in response to accelerating technological innovation, and realize in-factory rationalization and productivity improvements.
