The output is displayed on the CRT 22 as video display means. The printing device 20 can print the same hard copy as the video on the CRT 22 as well as the data stored in the storage means.

Next, registration of the tool shape and the tool unit shape will be described.

First, the outline of the tool will be generally described. In the tool registration, basic shape data representing the basic shape of the tool such as the tool shape and the name and size associated with the shape are registered.
Furthermore, tooling list, actually information of a plurality of tool units mounted on the machine, for example, the holder, the sleeve, the setting information der such tool information and the shift amount of such cutting tool is, registers it.

As described above, there are two types of registration data, and the tool information includes basic shape data such as holders and cutting tools, various shape data such as coordinates, vectors, and bitmaps, and tool shapes such as model numbers, names, and cutting edge sizes. It consists of information unique to each tool added to the data. Also, the touring list is
Since this is the setting information of the tool unit actually attached to the machine, in this registration, information necessary for creating the tool unit shape is registered. Also,
To create a list, search and read the tool information (model number, cutting edge size, etc.) of the holder (or holder and sleeve) and the cutting tool that constitute the tool unit from the data created by the tool registration from the shape data. In addition to the registration, the shift amount at the time of installation is also registered. If necessary, the processing steps performed by the registered tool unit, the chip name, the used chuck, and the like are also registered.

FIG. 2 generally shows the relationship of data in the tool registration. That is, when the tool registration 31 is performed, the tool registration data is classified into tool shape data 32 and tool information data 33 and registered. Tooling creation 34 is performed with reference to the tool information data 33, and a tooling list 35 is obtained by the registration.
