Abstract

PURPOSE:To conduct the preparation of a program, easily and briefly, by providing a number converting means for converting the numbers of tools into the numbers of tool pots in accordance with the data stored in a storage area so that the control program is made directly with the use of the tool numbers. CONSTITUTION:Control program data is written on a paper tape 1 with the use of tool numbers inherent to tools, and is read into an NC machine 2. The output signal of the NC machine 2 is delivered to a CPU 4 through a data bus 3. A program used in the CPU 4 is written in a memory 6 consisting of ROM and RAM having addresses in which the tool numbers corresponding to tool pot numbers (1) to (12) are written. The CPU 4 searchs the tool pot number corresponding to the tool number delivered to the CPU 4 in accordance with the data stored in the memory 6, and then, the obtained tool pot number is delivered to a tool drum control part 7.

プを＼ 変更する必要がある等の面倒があった。Conventionally,! Tool indexing control of the tool storage magazine in a Shinning Seven printer is performed by specifying the tool storage section number (hereinafter referred to as the toolbot number) of the tool pot in which the relevant tool is stored on the control program. I was making an allocation. For this reason, when creating a control program for the NC (@value control) device, the operator must decide on the method of machining the workpiece, the order of machining, the tools to be used, etc., and then decide what kind of tools to store in each tool pot. must be determined in advance, and at this time, the operator must consider the weight balance in the tool pot after storing the tools and the effective arrangement to reduce tool indexing time, etc. It is necessary to decide the tool storage position and work while checking the correspondence between tools and tool pot numbers.Also, if it is necessary to change the tool storage number after creating a chip, use the processing tape \ There were troubles such as having to make changes.

１０進２桁程度である。In addition, when replacing worn tools in the tool drum or when replacing tools with Jlll tools, check which tool box the tool to be replaced is stored in. Based on the correspondence of the pot numbers, the operator must check one by one and place the tool to be replaced in the specified position.In this case, the operator selects the cheapest tool pot number from the list showing the contents of the processing tape. Searching and indexing requires a lot of effort and work time, as it is necessary to continue rotating the tool drum until the necessary tool is indexed by manual operation. Note that the tool pot number is usually about two decimal digits.

くは、それ以上必要とされてきている。On the other hand, in recent years, the number of types of tools used has increased as machining operations have become more complex, and the classification of tools by type has been progressing. This classification tends to expand in the direction of large-scale tool numbers not only for machines but also for factories, companies, and even industries. As a result, the number of digits in the tool number is now required to be 100,000 to 100,000 (decimal double digits to six digits) or more.

等の問題がある。By the way, when creating a control data column, it is desirable to use the above-mentioned tool number as is. However, as mentioned above, current machining centers use decimal 2
Processing is now performed based on the unique tool pot number, and for this reason, the commands of the control program that are created based on the unique tool pot number with a large number of digits as described above can be used to control the conventional control device. It is impossible to index and control a machine directly using a machine, and in order to do this, it is necessary to create a separate tool assembly with particularly high reliability, and the manufacturing cost of the device is considerable. This poses a problem, such as the fact that it is difficult to adopt it practically.
