Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a check method in which a non-interference area of a machining program is set for two areas where fast feed and cutting feed are performed, and which is performed for these two set areas.

[0002]

[Prior Art and Problems] Conventionally, when machining a workpiece with a machining program, the interference check between the tool and the workpiece and the interference between the tool and the jig and other members are caused by a simulation method on a personal computer or an actual tool. The method of checking the interference between the workpiece and the work and the interference between the tool and the jig and other members is adopted. The method by simulation on the personal computer cannot check the actual interference state, and also checks the interference area between the tool and the work and the interference area between the tool and the jig and other members. Therefore, it is necessary to check the interference area of the tool for the extra space that has little relation to the interference with the movement of the tool with respect to the work.
The interference area check requires much effort and time.

Further, in the method of checking the actual interference between the tool and the workpiece and the interference between the tool and the jig and other members, the excess space, which is not so much related to the interference with the movement of the tool with respect to the workpiece, is on the spindle. The tool has to be moved to the object to be interfered with, and the interference area check also requires a lot of labor and time.

[0004]

In view of the above-mentioned conventional problems, the present invention sets a non-interference area in which a machining program is executed for two areas of fast feed and cutting feed, and It is intended to provide a check method for performing a setting area.

[0005]

According to the present invention, two non-interference areas of a rapid feed non-interference area and a cutting feed non-interference area are set by a probe for a workpiece on which a machining program is executed, and the two non-interference areas are set. A check method for a non-interference area of a machining program is characterized in that a machining program is executed for the interference area to check whether or not there is interference in the non-interference area.

According to the operation of the present invention, first, two non-interference areas, that is, a rapid feed non-interference area and a cutting feed non-interference area are set for a workpiece on which a machining program is executed by a probe attached to a spindle. After that, by executing the machining program for the two non-interference areas, it is possible to check the presence or absence of the interference in the non-interference area. If the interference occurs in the non-interference area, the "interference check screen" of the CRT is displayed. The axis type that has interfered with and its degree are displayed.

FIG. 4 is a perspective view of a table showing the setting, FIG. 4 is a front view of the table showing the setting of the cutting feed non-interference area of the present invention, FIG. 5 is a flow chart of the interference check, and FIG. 6 is a screen view of the interference check. .

1, 2, 3 and 4 show a state in which the non-interference area check method of the machining program according to the present invention is carried out. The work W on the table T of the machine tool M is attached to the jig G. ing. For the workpiece on which the machining program is executed, first, the maximum points P1 and P1 'and the minimum points of the probe P, which has two non-interference areas of the rapid feed non-interference area S1 and the cutting feed non-interference area S2 attached to the spindle, are provided. P2, P2
Set ´. After that, a processing program is executed for each of the non-interference areas S1 and S2 to check the presence or absence of interference in the non-interference area.
If interference occurs in the non-interference areas S1 and S2, the axis types X, Y, Z and their extents OOmm are displayed on the "interference check screen" of the CRT as shown in FIG.

The present invention is constructed as described above and operates as follows. In the flow chart of the interference check shown in FIG. 5, first, the probe P serving as a reference tool is attached to the main shaft (a). Next, setting (b) of the fast-forward non-interference area S1 which is the space above the work W is performed by reading the maximum point P1 and the minimum point P2 with the probe P attached to the spindle. Further, the cutting feed non-interference area S2, which is the space of the work W itself, is set (c) by reading the maximum point P1 'and the minimum point P2' with the probe P attached to the spindle.

Subsequently, the machining program is executed for each of the non-interference areas S1 and S2 to check the presence or absence of interference in the non-interference area. If there is interference in S1 and S2 in the non-interference area and an alarm is generated (g), the axis types X, Y, Z and their extent OOmm are displayed on the "interference check screen" of the CRT as shown in FIG. To do.
Here, the interference program is corrected (h), and the presence or absence of interference in the non-interference area is checked again (d). If there is no interference (e), the process ends (f).

It is needless to say that the present invention is not limited to the above-mentioned one embodiment, and design changes can be made within the scope of the invention.

[0012]

[Effect] According to the check method of the non-interference area of the machining program according to the present invention, the non-interference area such as the rapid feed non-interference area and the cutting feed non-interference area which are close to the work is checked, so that the work can be performed like the conventional method. It is not necessary to check the interference area of the tool in the excess space that is not so much related to the interference with the movement of the tool with respect to the tool, and there is an effect that the interference area check can be performed simply and in a short time.
