Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention automatically creates NC machining data for each work machining production equipment machine from part drawing data by CAD (computer-aided design) or the like, and provides consistent production. The present invention relates to a machining information creating apparatus for an automatic machining machine that supports the CAM (computer-assisted manufacturing) of a system, and more particularly to a machining information creating apparatus for an automatic machining machine capable of subdividing a machining area for each set tool.

<Prior Art> FMS is now in a practical stage as a representative of a flexible automatic production system. In the FMS, the computer operates the schedule plan, machining, setup plan, tool supply plan, etc. online, but the structure of the machining information creation device that downloads from the presentation of the component drawing data corresponding to the higher order to the FMS.

That is, it is a practical automatic machining information creation device having both consistency and flexibility that directly connects NC drawing data that can be immediately used for automatic production from parts drawing data and minimum setting data.

<Problems to be Solved by the Invention> In the above-described machining information creation device for an automatic machining machine, a machining area is divided into each tool and data is set as a divided machining area for each tool. The set machining area for each tool is set with machining condition data and cutting condition data, which will be described later, and is reflected in the final NC machining data. In the setting processing of the divided machining area for each tool, in order to improve the normal processing efficiency, when a specific tool is determined by the reference data, a single machining condition and cutting condition are set in association with the specific tool.
However, in actual machining, it is not always necessary to set the same conditions for the machining area of a specific tool. For example, as shown in FIG. 3 (b), when machining a set machining area in a tool of TO1, when machining under machining conditions in the cutting direction X, the dotted line in the figure Chatter may occur only inside and the finish may not be good. Further, in terms of machining efficiency, it may be preferable in terms of machining technology to subdivide machining conditions and cutting conditions even for the same tool.

In view of the above circumstances, an object of the present invention was proposed to solve the problem, in which a machining area set by a specific tool is further subdivided into several cutting groups and set, By adding an information search number at the beginning of the group, it is possible to individually set the processing conditions and cutting conditions for specific group data, and to improve the processing accuracy and processing efficiency while maintaining processing efficiency. It is to provide a processing information creation device in a processing machine.

<Means and Action for Solving Problems> In the present invention, means for solving the above problems are as follows.
