コンピュータにより、管理する場合に利用できる。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to the management of NC data of equipment (for example, NC machine tools, robots, etc.) having an NC device using one or more computers. can.
従来の技術
ＣＰＵとＮＣ装置が接続されている構成において、目的
のＮＣデータをＮＣ装置で駆動するための方法に、従来
の技術の代表例として、次の２つの方法がある。Conventional Technology In a configuration in which a CPU and an NC device are connected, there are the following two methods as representative examples of conventional technology for driving target NC data on the NC device.
（１）第２図に示す如く、ＮＣ装置内には常に１本のＮ
Ｃデータしか格納されていない。すなわち、必要なＮＣ
データは、その都度毎回、記憶装置内のＮＣデータファ
イルよシ探し、対象ＮＣ装置に送信する方法である。(1) As shown in Figure 2, there is always one N in the NC device.
Only C data is stored. That is, the required NC
Each time, the data is searched for in the NC data file in the storage device and sent to the target NC device.
（２）第３図に示す如く、ＮＣ装置毎に、各ＮＣ装置で
使用するＮＣデータを予め全て格納、登録しておく。Ｃ
ＰＵはＮＣデータ名（Ａ）を各ＮＣ装置に伝送する方法
である。(2) As shown in FIG. 3, all NC data used in each NC device is stored and registered in advance for each NC device. C
PU is a method of transmitting the NC data name (A) to each NC device.
なお、駆動するＮＣデータ名を伝送しても、該当のＮＣ

ＮＣデータ対応の物品しか生産ができないため、多品種
少量生産への即応が難しかった（ＮＣデータをオフライ
ンで入れ替える必要がある）。Problems to be Solved by the Invention In the method (1) of the prior art, NC data is transmitted each time 1 unit of production is performed, so it is possible to flexibly respond to high-mix, low-volume production. When producing the same product continuously, the NC data is transmitted each time even though the data is already in the storage device of the NC device, resulting in a large transmission time loss. (Operating loss of 2 to 6% occurs) Furthermore, in method (2) of the conventional technology, the product to be produced is fixed for each M/C, and the corresponding NC data is
Since it is stored in the storage device on the device side, there is no need to transmit the NC data, and there is little transmission time loss. but,
Storage capacity is limited, and only items compatible with the NC data stored in the storage device can be produced, making it difficult to quickly respond to high-mix, low-volume production (NC data must be replaced offline).
本発明は、これらの問題点を解決し、多品種中少量生産
に柔軟に対応し、かつＮＣデータの切替時間ロス（伝送
時間ロス）を軽減しようとするものである。The present invention aims to solve these problems, flexibly cope with high-mix, medium- to low-volume production, and reduce NC data switching time loss (transmission time loss).

Also, CPU
On the side, the NC stored in each NC device is stored in the storage device.
In addition to managing data storage, the last NC data is kept replaceable (see Figure 1), and if the NC data specified by the CPU is not in the NC device, the corresponding N
Search for the C data in the NC data file on the CPU side, replace it with the last NC data, and send it to the NC device.
