Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a numerical control device for a contour processing machine.

[Conventional technology]

In the conventional numerical control device, as shown in Fig. 2,
The contour machining machine control section 2 receives machining data from the data input section 1, and controls the contour machining machine (not shown) based on this machining data. Here, the machining data includes not only the machining shape data including the coordinates of the machining shape, which is the basis of the external machining data, but also machining conditions such as the feed rate and rotation speed of the machining tool, and the feed rate of the machining table, and the machining tool. It contains a mixture of machining operation determination data such as a rise and fall command, a dust suction operation command, and a pressure foot pressurization command. In other words, the machining data includes information that corresponds one-to-one with all operations of the contour machining machine.

[Problem that the invention seeks to solve]

The conventional numerical control device described above requires information corresponding to all operations of the contour processing machine as input data. This requires a large number of man-hours to create data in the data creation process that is a pre-process of external shape processing. The reason for this is not only machining shape data that can be easily obtained from drawings, but also machining conditions such as the feed rate and rotation speed of the machining tool, the feed rate of the machining table, the raising/lowering command of the machining tool, the dust suction operation command, and the pressure foot application. This is because pure mechanical operations of the contour processing machine, such as machining operation commands such as pressure commands, must be determined in the data creation process.

[Means for solving problems]

The external shape machining numerical control device of the present invention includes a data input section that reads machining data from a data medium, and a machining condition optimization/machining operation that receives the machining data from the data input section and automatically generates machining condition data and machining operation determination data. The apparatus includes a determining section, and a contour machining machine control section that controls the contour machining machine based on the machining condition data and the machining operation determination data received from the machining condition optimization/machining operation determining section.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing an embodiment of the present invention, a machining condition optimization/machining operation determining section 3 is constituted by a microcomputer. The data patterns of the machining condition data and machining operation determination data are stored in R and OM (read-only memory) of the machining condition optimization/machining operation determination section 3.

In particular, the machining condition data is stored with optimum values set in units of the diameter of the machining tool. The information included in the input data is only XY coordinate data indicating the machining shape and data on the diameter of the machining tool.

Usually, the order of the data is the diameter of the processing tool, the start point, relay point (bending point), and end point of the processing shape, and a set of repetitions thereof becomes processing data for one workpiece, such as a printed wiring board.

When the external machining starts, the machining condition optimization/machining operation determining unit 3 receives data from the data input unit 1, and if the diameter data of the machining tool is read, the tool exchange data, which is the machining operation determination data, is input. is read from the ROM, and the optimum value of the diameter is read from the ROM as tool rotation speed data, which is machining condition data, and is delivered as is to the contour processing machine control section 2. Next, when the coordinate data indicating the starting point of the machining shape is read from the data input unit 1, machining operation determination data for moving the machining table at idle is read from the ROM and added to the coordinate data, and the data is passed to the control unit 2. , and the optimum value of the diameter is read from the ROM as tool downward feed rate data, which is machining condition data, and handed over as is to the control unit 2, and further machining operations such as tool downward movement data and dust extractor operation start data are carried out. The decision data is read from the ROM and delivered to the control unit 2. Next, de =
When the seat frame data indicating the relay point of the machining shape is read from the input unit 1, the machining operation determination data of table cutting movement is included in the coordinate data, and the table feed rate data, which is one of the machining condition data, is added to the coordinate data. fi for diameter
An appropriate value is read from the ROM, added, and passed to the control section 2.

Next, when the coordinate data indicating the end point of the machining shape is read from the data input unit 1, in addition to the functions for the relay point, the pressure foot pressurization command data, tool upward movement data, and dust suction machine operation stop are performed. Processing operation determination data such as data is read from the ROM and handed over to the control unit 2 as is.

In the above embodiment, the setting of the feed rate of the machining table was determined only by the diameter of the machining tool, but by varying the set value of the feed rate of the machining table depending on the distance between the relay points of the machining shape data, it is possible to Allows for precise control.

〔Effect of the invention〕

As explained above, according to the present invention, the machining condition optimization/machining operation determining section automatically determines the optimal machining conditions and machining operations without including machining condition data or machining operation determination data in the input data. , the amount of input data can be reduced.

Thereby, the number of man-hours for creating input data can be reduced.
