2. Description of the Related Art Conventionally, in a numerical control information generating apparatus, an operator inputs a machining shape, a tool to be used, cutting conditions and the like while looking at a machining drawing, and the numerical control information generating apparatus makes the numerical control work based on the inputted data. I was creating a numerical control program that machined. Particularly, in the generation of the tool path, the tool path is generated based on the input machining shape and the data of the tool used.

FIG. 4 is a block diagram showing the configuration of a numerical control information generating apparatus for generating the above-mentioned tool path. The numerical control information generating apparatus has a data input device 1 such as a keyboard for inputting data. The data input device 1 is connected to the input processing means 2 for checking the input data. The input processing means 2 is connected to a shape processing means 3 for determining a shape to be processed from the input data, and the shape processing means 3 is provided with a movement path of a tool for processing the determined processing shape. The tool path generating means 4 for generating is connected.

Next, the operation will be described. The operator inputs necessary data (machining shape, tool to be used) through the data input device 1 while looking at the machining drawing. Then, the input processing means 2 checks the input data, and the shape processing means 3 determines the shape to be processed from the input data.
Then, the tool path generation means 4 creates a movement path of the tool for processing the machining shape determined by the shape processing means 3, and thereby the numerical control program 5 is created.

[0005]

The conventional numerical control information generating device is configured as described above, and recently, in order to simplify the designation method when designating a machining shape, a square (□) or A method has been proposed in which a machining shape can be easily designated by designating a basic shape such as a circle (o) or an oval (0). Here, the basic shape is a basic figure such as a square (□) or a circle (○). Therefore, for example, when a character such as a part name or a product name (for example, the character AB001) is processed on a workpiece, the character is divided into a straight line or a circular arc because these basic shapes (basic figures) do not exist. It is necessary to specify the shape, and the shape specification becomes complicated, and the time for creating the numerical control information becomes long.

The present invention has been made in order to solve the above problems, and provides a numerical control information generating apparatus capable of easily generating a tool path even when a character shape is registered in advance and the character shape is processed. The purpose is to do.

[0007]

The present invention has been made in view of the above circumstances, and a numerical control information creating apparatus according to the present invention includes a character shape registration means for registering shape data corresponding to a character, Character shape selection means for selecting shape data corresponding to a desired character from shape data corresponding to the characters registered in the character shape registration means, and shape data corresponding to the desired character selected by the character shape selection means. And a tool path generating means for generating a tool path based on the tool path.

[0008]

According to the above-described structure, the numerical control information creating apparatus according to the present invention registers the shape data corresponding to the character by the character shape registration means, and selects the desired shape data from the shape data corresponding to the character registered in the character shape registration means. The shape data corresponding to the character is selected by the character shape selection means, and the tool path generation means generates the tool path based on the shape data corresponding to the desired character selected by the character shape selection means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a numerical control information creation device according to the present invention. The same parts as those described above are designated by the same reference numerals and the description thereof will be omitted. A character shape registration means 10 for registering shape data corresponding to a character is connected to the input processing means 2, and the input processing means 2 and the character shape registration means 10 are registered in the character shape registration means 10. Character shape selection means 1 for selecting shape data corresponding to a desired character from shape data corresponding to a character
1 is connected, and the character shape selection means 11 is connected to the shape processing means 3.

Next, the operation of this embodiment will be described.
The operator inputs shape data corresponding to a character as a processing shape from the data input device 1, and the input processing means 2
The input data is checked, the input data is sent to the character shape registration means 10, and the shape data corresponding to the character is registered and stored. For example, as shown in FIG. 2, when the character “P” is registered and stored, the character “P” is divided and registered in a shape such as a straight line or an arc. (X0, Y0) is the coordinate of the reference point that determines the machining position, and may be set in advance or may be determined by the operator's input each time.

Next, the generation of the tool path will be described with reference to the flowchart of FIG. When processing a character shape, the operator gives an instruction to process the character shape using the data input device 1, and inputs a character to be further processed (a character string including a plurality of characters may be used). Then, the input processing means 2
Checks the input data and determines whether or not the character shape is designated (step 1). When it is determined that the character shape is designated, the character data input to the character shape selection means 11 is sent. , The character shape selection means 11
The shape data corresponding to the input character is searched (step 2) and sent to the shape processing means 3. Then, the shape processing means 3 determines the received data as the shape data corresponding to the character (step 2), and the tool path generation means 4
Generates a movement path of a tool for machining the determined machining shape, and the numerical control program 5 is created. In addition,
In the above embodiment, the character "P" of the alphabet has been described as an example of the character to be registered, but the character to be registered is not limited to this and may be a number, a hiragana, a katakana, or a kanji. Also,
It is possible to select the character size and font.

[0012]

As described above, according to the numerical control information creating apparatus of the present invention, the shape data corresponding to a character is registered in advance, and when a desired character is input, the shape data corresponding to the character is entered. Is selected and the tool movement path is generated based on the shape data, so when machining characters, there is no need to divide the characters into straight line or arc shapes, and there is no need to specify complicated shapes. Therefore, the time for creating the numerical control information can be shortened.
