DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interactive programming apparatus for creating a machining program for a numerically controlled machine tool, particularly a grinding machine.

[0002]

2. Description of the Related Art In a grinding machine, one grinding surface is generally ground by combining a plurality of grinding cycles in view of the characteristics of the grinding process. In this case, if one grinding cycle is considered as one grinding process, the grinding process is performed by using a plurality of types of grinding processes or by continuing the same grinding process as the other grinding process such as roughening and finishing. In such a case, or in the case where a process other than a grinding process such as a dress cycle is inserted in the middle of the process to perform the grinding process, the order of the grinding process differs depending on the material or characteristics of the workpiece / grinding wheel.

In order to cope with this, even an interactive programming device is generally capable of designating an arbitrary number of grinding steps on one ground surface. There are roughly the following two methods for creating a machining program using such an interactive programming device. That is, a method in which the grinding process is programmed in accordance with the processing order and a method in which the grinding process is sequentially programmed for each ground surface. In both methods, a grinding program and a grinding sequence are changed for each process while performing trial grinding or the like, and a so-called process editing function enables creation of a machining program optimal for a workpiece, a grinding wheel, and the like.

FIG. 6 is a block diagram showing an example of a conventional interactive programming apparatus. Each grinding process according to a machining procedure input from a keyboard 1 in an operation panel 8 to a grinding process data creating unit 2 and its grinding process. Processing shapes and related to the grinding process
Grinding process data GD for each grinding process is created based on processing data KD such as grinding conditions and grinding directions, and stored in the grinding process data storage unit 4 sequentially.

[0005] A series of grinding process data groups GDB stored in the grinding process data storage unit 4 are read out by the machining program creation unit 5 to create a machining program. Display control unit 6
And numerically displayed on the CRT display device 7 in the operation panel 8. When it is necessary to modify the already created grinding process data by trial grinding or the like, the data is stored in the grinding process data storage unit 4 based on the correction data KD input from the keyboard 1 to the grinding process data editing unit 3. The series of grinding process data groups GDB that have been read are read out by the grinding process data editing unit 3, corrected, and stored again in the grinding process data storage unit 4.

[0006]

The method of instructing the grinding direction in the above-mentioned conventional interactive programming apparatus is roughly classified into the following two methods. One is a final shape standard based on a final shape described in a processing drawing, and the other is a material shape standard based on a material shape before grinding of a workpiece. When programming the grinding direction command, command the relative amount called the grinding amount and the grinding start position and the grinding completion position which are the absolute position commands, and use the defined workpiece shape to determine the remaining machining allowance if the final shape is the basis. If it is a shape standard, command the grinding amount. In other words, if two commands, that is, the grinding amount for each grinding step and the remaining machining allowance or the already-milled amount of one grinding surface are added, the total grinding allowance of the ground surface is always obtained, and the validity of the command can be checked. However, in the method of confirming the grinding amount and the remaining machining allowance or the existing grinding amount for each grinding process of one grinding surface only by the displayed numerical value, the relationship between the total machining allowance of the grinding surface and the grinding amount for each grinding process is correctly maintained. This is not easy, and there is a possibility that a collision accident occurs between the grinding wheel and the workpiece, which is very dangerous.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an interactive programming apparatus capable of displaying a grinding amount or the like for each grinding step of one grinding surface in a bar graph or the like. Is to provide.

FIG. 1 is a block diagram showing an example of an interactive automatic programming apparatus according to the present invention in correspondence with FIG. 6, and the same components are denoted by the same reference numerals and description thereof will be omitted. The grinding process data group GDG of one ground surface in the grinding process data group GDB stored in the grinding process data storage unit 4 is read out to the display control unit 6 and the graph display control unit 9. The grinding amount for each grinding process of the grinding process data group GDG read out by the graph display control unit 9 and the remaining machining allowance or the already-ground amount are the same for each grinding process.
The graphs are arranged and graphed in the order of execution , and the display switching unit 10 combines the graph DG with the numerical value from the display control unit 6,
Alternatively, the display is switched independently.

An operation example of such a configuration will be described with reference to the flowchart of FIG. The display control unit 6 and the graph display control unit 9 read out the grinding process data group GDG of one ground surface from the grinding process data storage unit 4 (Step S1). The graph display controller 9 calculates the scale of the graphic screen in accordance with the total removal amount of the readout grinding process data group GDG (step S2), and determines the grinding amount for each grinding process and the remaining removal amount or the already-ground amount in each grinding process. A graph DG arranged in the execution order is created and sent to the display switching unit 10 (step S3). On the other hand, the display control unit 6 sets the numerical value D of the grinding amount and the remaining allowance for each grinding process of the read grinding process data group GDG.
N, or a number DN of the grinding amount and already grinding amount of the grinding step
They are arranged in the order of execution and sent to the display switching unit 10 (step S4).

The display switching unit 10 determines whether the display mode is a composite display, a single display and a graph display, or a single display and a numerical display (step S5). In the case of (1), the title of the graph display screen such as the title message is displayed (step S6), the screen shown in FIG. 3 is displayed on the CRT display device 7 (step S9), and all the processes are ended. On the other hand, in the determination step S5, when the display mode is the single display and the numerical display is performed, the title of the numerical display screen is displayed (step S7), and the screen shown in FIG. 4 is displayed on the CRT display device 7 (step S7). S9), end all processing. On the other hand, if the display mode is the composite display in the determination step S5, the title of the composite screen is displayed (step S8), and the CRT display device 7 displays, for example, FIG.
Is displayed (step S9), and all the processing ends.

In the above-described embodiment, the grinding amount and the like are displayed in a bar graph. However, it is also possible to display the grinding amount in a graph other than the bar graph. Also, if the grinding start position for each grinding step arranged in the execution order is displayed in a discontinuous graph, it is easy to recognize that there is any command error, and this is indicated by the alarm / error on the interactive programming device side. If a warning is given to the operator through a display or the like, an even safer program can be created.
