Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of creating a tool unit shape used for registering a tool unit shape used for machining a work (workpiece).

[0002]

2. Description of the Related Art Generally, a machine tool such as a turret lathe can perform several kinds of machining on one work, and various tools are selected according to the machining. In addition to the types of tools such as a bite and a drill, the selected tools have different sizes and shapes even if they are of the same type. In short, in this type of machine tool, there is a selection of a plurality of tools and their combinations depending on the work, and there are innumerable selection elements. Therefore, facilitating the selection of these tools and the creation of their combination is useful for alleviating the requirement of the skill of the operator, speeding up the processing, and enhancing the reliability of the processing.

[0003]

By the way, conventionally, NC
As a method of verifying a machining command (program) in the device, there is a method of simulating on a display. The purpose of verifying this processing command is as follows. a. Confirmation of work shape of work b. Interference check between work and tool c. In case of NC device capable of simultaneous multi-axis control, interference check between tools

For these purposes, cases a and b can be realized by displaying the shape of the work to be machined and the cutting tool such as a cutting tool or a drill. However, there is a case where a tool unit shape, that is, a state in which a tool and a holder for fixing the tool to the machine tool are combined is required to be displayed in c. In that case, conventionally, the tool unit shape was registered, but for the combination of the cutting tool and the holder, there are multiple types of cutting tools that can be selected for one cutting tool holder, and considering the relationship with the shift amount during mounting, There are innumerable combinations. Therefore, when a machining program is newly created, it is necessary to register the shape of the tool unit each time the simulation is performed.

Therefore, it is an object of the present invention to provide a method of creating a tool unit shape that simplifies the registration work of the tool unit shape.

[0006]

As shown in FIGS. 1 and 2, the method for creating a tool unit shape according to the present invention registers the shape of each tool constituting the tool unit, and
The setting information of the tool is registered, the position where the holder shape and the tool shape are combined is calculated from the tool size (blade size Q) and the shift amount (P), and these are combined to create the tool unit shape. And

[0007]

The minimum unit of the tool unit is a tool such as a cutting tool or a holder. The shape of this tool is registered and the setting information of this tool is registered. The setting information is physical information such as a holder shape, a cutting tool shape, a cutting tool size, and a shift amount. Then, such registered information can be arbitrarily read.

Therefore, when the shape of the workpiece to be machined is determined, a tool corresponding to the machined shape is selected. The position where the holder shape and the tool shape are combined is calculated from the tool size and the shift amount, and these are combined to create the shape of the tool unit.

Therefore, in this tool unit creating method, it is possible to create a plurality of tool unit shapes by utilizing the tool shapes that have already been registered, and as a result, the amount of work for shape registration is greatly reduced. . The machining of the workpiece and its simulation can be performed using the tool unit shape created by the method for creating the tool unit shape of the present invention. The application covers a wide variety, such as application to simulations.

The output is displayed on the CRT 22 as a video display means. In addition to the same hard copy as the image on the CRT 22, the printing device 20 can print the data stored in the storage means.

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

First, to give a general description of the outline, in the tool registration, the tool information such as the tool shape and the name and size associated with the shape are registered. Also, the touring list is
Information about a plurality of tool units actually attached to the machine, for example, tool information about a holder, a sleeve, a cutting tool, and setting information such as a shift amount, is registered.

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, bitmaps, tool shapes such as model numbers, names, and cutting edge sizes. It consists of information unique to each tool that is added to the data. Also, the touring list is
Since it is the tool unit information actually attached to the machine,
In this registration, necessary information for creating the tool unit shape is registered. In addition, the list creation work is performed by searching the shape data for the tool information (model number, cutting edge size, etc.) of the holder (or holder and sleeve) and cutting tool that make up the tool unit from the data created by tool registration, Along with registering to the list, the shift amount at the time of mounting is also registered. If necessary, the machining process performed by the registered tool unit, chip name, chuck used, etc. are also registered.
