Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling the display of drilling status in a numerically controlled machine tool.

Conventionally, when creating a drilling program for a numerically controlled machine tool, it has been necessary to specify each tool to be used that is compatible with the machining shape. Therefore, the creation of a machining program for numerically controlled machine tools for drilling has been done by a programmer determining the tools to be used and the order in which they are used, based on the final machining shape shown in the drawing. Not only does this work require a lot of time and effort, but it also requires programmers with extensive specialized knowledge in addition to operators, which has been an obstacle to its widespread use. Therefore, methods have been taken to simplify the program creation work through automatic programming and to solve the above-mentioned disadvantages. However, at the check stage of the program, even if the old method is still displayed on the display device, it is simply displayed as a single line. During processing, they overlap,
It could not be said that the check function was sufficiently fulfilled in practical terms.

In view of the above circumstances, the present invention stores in a combination pattern memory a tool row in which the names of tools assigned designated colors used for machining each machining unit are arranged in the order of use, and the corresponding tools are selected from the graphic pattern memory. call a pattern for
A drilling processing status display control method for a numerically controlled machine tool configured so that the pattern is registered in a graphic registration memory according to a specified color, and when a display request is made, the pattern can be graphically displayed in a different color for each tool. The purpose is to provide the following.

The present invention will be specifically described below based on embodiments shown in the drawings.

Fig. 1 is a control block diagram of a numerically controlled machine tool to which the present invention is applied, Fig. 2 is a diagram showing a drilling unit, Fig. 3 is a sectional view showing the machining shape of the drilling unit, and Fig. 4. 5 is a schematic diagram showing the contents of the combination pattern memory, and FIG. 5 is a diagram showing an example of the contents recalled from the graphic registration memory and displayed on the display.

The numerically controlled machine tool 1 has a main control section 2, as shown in FIG. A memory 7 and a screen control section 8 are connected, and a drilling processing calculation section 9 and a general processing calculation section 10 are further connected to a combination pattern memory 11.
In addition, the screen control unit 8 includes a graphics registration memory 1.
2 and a graphic pattern memory 13 are connected.

Since the numerically controlled machine tool 1 has the above configuration, when creating a drilling program, the main control section 2 displays the machining unit from the machining unit memory 5 on the display 4 and prompts the operator to draw it in the drawing. The user selects which machining unit the displayed drilling shape belongs to and inputs it from the keyboard 3. That is, the processing unit memory 5 stores a plurality of processing units a as shown in FIG.
~i are recorded, and all patterns of drilling are covered. Therefore, the operator can immediately select and input the required machining unit by referring to the final machining shape displayed on the drawing and the machining shape of each machining unit. When the machining unit is input, the machining shape control section 6 displays requests for the machining hole diameter, machining hole depth, chamfer amount, etc. according to the machining unit selected on the display 3, and then inputting them from the keyboard 3. Let them input. Next, the main control section 2 reads out the tool sequence TCL corresponding to each processing unit from the combination pattern memory 11, and outputs it to the drilling operation calculation section 9 in the case of drilling. That is, in the combination pattern memory 11, as shown in FIG. 4, the names of the tools used for machining each machining unit are arranged in the order of use from the left in the figure as a tool row TCL, and the machining unit is specified. The tool row corresponding to the relevant machining unit is immediately
The TCL is output all at once to the drilling calculation section 9. Note that a designated color CLR is assigned to each tool name in the tool pattern memory 11, and the designated color CLR is also output to the drilling calculation section 9 at the same time. The drilling calculation section 9 determines the tool diameter for each selected tool based on this information, and sequentially determines the tool trajectory. On the other hand, when the tool diameter, machining depth, etc. are determined by the drilling calculation unit 9, the screen control unit 8 calls up a pattern for the tool from the graphic pattern memory 13, and uses the specified color.
It is registered in the graphics registration memory 12 according to the CLR, and when a request for graphic display is made, the screen control section 8 can call from the graphics registration memory 12 and display it on the display 3 via the main control section 2. Now, if the drill hole machining unit is input by the operator, the address will be input from the combination pattern memory 11 as shown in FIG.
Compatible with ADS 001 and later drill hole machining units. The tool sequence TCL of spot drill, drill, and chamfer cutter is output all at once to the drilling processing calculation unit 9, and at the same time, as the specified color CLR, CLR1 for the spot drill, CLR2 for the drill, and CLR2 for the chamfer cutter. CLR4 is output. The calculation section 9 sequentially calculates and determines the diameters and machining depths of the spot drill, drill, and chamfer cutter. These results are stored in the program registration memory 7 via the main control unit 2.
stored inside. On the other hand, if a spot drill is specified, the screen control unit calls the spot drill pattern from the graphic pattern memory, and registers it in the graphic registration memory 12 with information on the tool diameter and machining depth according to the specified color CLR1. Ru. The same applies to drills and chamfer cutters.
When there is a request to display a graphic pattern registered in the graphic registration memory 12 in this way, the spot drill is executed by CLR1, as shown in FIG.
Drills can be displayed in CLR2 and chamfer cutters can be displayed in CLR4.

As explained above, according to the present invention, the combination pattern memory 11 stores a tool row TCL in which the tool names to which the specified color CLR used for machining the machining unit is assigned are arranged in the order of use, and the tool trajectory is determined. At the same time, the pattern for the corresponding tool is called from the graphic pattern memory 13 and registered in the graphic registration memory 12 according to the specified color CLR, so that when a display request is made, each tool is graphically displayed in a different color. Therefore, the operator can easily identify the tools used during drilling and the machining conditions, which can contribute to reducing programming errors.
