Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a repetitive groove shape in an interactive automatic programming function for collectively designating a final part shape and creating a numerical control program based on the shape data. Regarding the batch input method of.

(Prior Art) Conventionally, in the interactive automatic programming function for creating a machining program for a numerically controlled machine tool by collectively inputting the part shape after machining of the workpiece, that is, the final part shape by interactive operation, When inputting an element, generally, a method of defining a part shape in the order of turning shape element → groove shape element → turning shape element is adopted.
However, according to this method, a part shape in which a plurality of grooves of the same shape are present in succession is formed in the order of turning shape element → groove shape element → turning shape element → groove shape element → …… → turning shape element. I had to define it.
Therefore, in such an input method, the number of input operations by the operator is increased according to the number of groove-shaped elements.

In such a case, as a means for easily inputting the repetitive groove shape, a specified number of groove shape elements are created by specifying the reference groove shape data, the number of repetitions, and the groove shape interval. A way to do it was figured out.

(Problems to be Solved by the Invention) However, also in the above-described input method, since the operation of inputting the repetitive groove shape is independently performed, the repetitive groove shape element that can be defined is parallel to the Z-axis and the X-axis. There was a problem that it was limited to things. Therefore, in order to define the repeated groove shape in the tapered or arcuate part of the part shape, the means of collectively inputting the repeated groove shape cannot be used. As described above, one turning shape element and one groove shape element must be input. In the end, the operator was left with a burden on the operation.

The present invention has been made under the circumstances as described above, and an object of the present invention is to make it possible to collectively input repeated groove shapes even when defining a taper portion or a circular arc portion of a component shape. It is to provide a batch input method of repetitive groove shapes capable of reducing the load.

(Means for Solving the Problems) The present invention relates to a batch input method of repetitive groove shapes in an interactive automatic programming function for collectively designating final part shapes and creating a numerical control program based on the shapes. The object of the present invention is to specify the shape data for forming the groove shape element, the number of repetitions thereof, and the interval thereof for the already input turning shape element, whereby A shape element is generated along the shape on the turning shape element, and a shape element that connects between the well-meaning groove shape elements is automatically divided and generated from the turning shape element while holding the processing information. To be achieved.

(Operation) In the present invention, when repeatedly inputting the groove shape,
With respect to the already entered turning shape element, the turning shape element is divided by the specified number of groove shape elements only by specifying the shape data forming the groove shape element, the number of repetitions of the shape data, and the intervals between them. The original turning information can be held for the shape element, and can be collectively input regardless of the shape of the turning shape element.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing.

Based on the shape storage unit 3 and the information of the part shape from the data input unit 2, when the shape cannot be uniquely determined only by the input data, the intersection calculation unit 4 that automatically calculates the intersection from the relationship of the shape elements before and after the input data.
And a part shape storage unit 5 in which information on the part shape from the intersection calculation unit 4 is stored, and a display control unit that controls display of the material shape from the data input unit 2 and the part shape from the intersection calculation unit 4. 6, a display device (CRT) 7 for inputting and displaying the information from the display control unit 6, material shape information from the material shape storage unit 3, and component shape information from the component shape storage unit 5. And a numerical control information creating section 8 which creates numerical control information based on the above.

FIG. 2 is a flow chart showing the batch input method for repeating groove shapes according to the present invention. FIG. 3 is a diagram showing an example of the shape of the component before adding the repetitive groove. FIGS. 4 (A) and 4 (B) are diagrams showing a groove shape data input screen and a specific input method. FIG. 5 is a diagram showing an example of the shape of the component after adding the repetitive groove.

Hereinafter, the procedure of the present invention will be described with reference to FIGS. 1 to 5. This procedure is performed by the intersection calculation unit 4 in FIG.

In the interactive automatic programming function for collectively inputting the final part shape, it is assumed that the result of inputting only the turning shape element is as shown in FIG. In FIG. 3, the operation of adding three repeating groove shapes on the tapered turning element l ₂ will be described as a specific example. Assuming that the shape element sequence is defined in the counterclockwise direction from the starting point S of the shape definition, the tapered lathe shaped element l ₂ is the _second shape element of all the shape elements.

First, by using a means such as moving the cursor, a shape element to which a groove shape element is added (l _{2 in} FIG. 3) or a shape element to be corrected or deleted is designated from the shape element sequence. (Step S1). Next, it is determined whether or not a groove shape element is added in order to specify what kind of processing should be performed on the specified shape element l ₂ (step S2). Here, if it is not the process of adding the groove-shaped element, the process proceeds to another process. On the other hand, when adding a groove-shaped element, a screen (FIG. 4 (A)) prompting the user to input information about the groove-shaped element is displayed.

Here, FIG. 4 (A) is an example of a data input screen for designating the groove shape, and a shape element string is graphically displayed in the right half of the screen. At this time, the shape element l ₂ to be processed can be easily distinguished from other shape elements by a method such as changing the display color.

In such an input screen, one groove shape that is the basis of the repeated groove shape according to the shape definition direction (counterclockwise)
Enter the data (start point, end point, depth, etc.) necessary to confirm G1. That is, first, as shown in FIG.
The direction of the groove shape, that is, the cutting method of the groove is designated (in the case of the figure, the direction is + X to −X (↓)). Next, the groove shape definition starting point A of the reference groove shape G1 is designated on the turning shape element l ₂ to which the repeated groove shape is to be added. The coordinate value of the point A is determined from the condition that it is on the turning shape element by inputting either the X or Z coordinate value. Further, the depth of the groove shape is the distance ▲ ▼ from the starting point of the groove shape definition in the direction of the groove shape. Further, by inputting the groove width ▲ ▼ or the coordinate value of the point D, the reference groove shape G1 (=
ABCD) is confirmed (step S3).

Then, the number of groove shapes is designated. For example, the groove shape is 1
If there is only one, the number of groove shapes may be set to 1 (step S4).

Furthermore, in order to define the repeating groove shape, the groove shape interval must be specified. In FIG. 4, this distance is inputted by calling the distance from the groove shape definition start point A to the next groove shape start point A'parallel to the Z axis as a shift amount (step S5).

When receiving more items without contradiction, the same groove shape elements G1 are created one after the other along a defined direction of turning shape element l _2. That is, the original tapered turning shape element l ₂ is three groove shape elements G1, G2, G3 having the same shape, and shape elements l _{21 to} l ₂₄ generated so as to connect the groove shape elements. The shape changes to. At this time, the shape elements l ₂₁ ~ l
₂₄ is automatically divided based on the input data of the repetitive groove shape while retaining the processing information (surface roughness etc.) of the original turning shape element l ₂ .

In this way, the shape element string to which the groove shape elements are added is graphically displayed (step S6), whereby the operator determines whether or not the data input by the operator is correct (step S7). If the data you entered is not correct, go back to step S3, re-enter the data,
If it is correct, the operation of adding the groove shape is ended.

In the above embodiments, the case where the repeating groove shape is defined along the taper shape has been described. However, if an arc is specified as a turning shape element to which the groove shape is added, the repeating groove shape can be formed in the same procedure. It is also possible to define so as to follow an arc shape.

(Effects of the Invention) As described above, according to the batch input method for repetitive groove shapes of the present invention, when defining a part shape in which a plurality of grooves having the same shape are continuously present, the turning operation input in advance is performed. Since the groove shape can be collectively specified on the shape element regardless of the shape of the turning element, the number of input operations by the operator is reduced, and the input error is also reduced accordingly.
