(3) Operation screen When the operation search menu key 42 is pressed, as shown in FIG. 34, the color CRT 3 displays an operation search screen. From this screen, the operation list preparation menu key 42 is pressed. Move to the operation list creation screen.

(3-1) Operation List Creation Screen When the operation list creation menu key 42 is pressed, the color CRT 3 displays an operation list creation screen as shown in FIG. This operation list creation screen is composed of two screens, a screen of FIG. 29 and a list data input screen of FIG. First, the display fields on the screen of FIG. 29 are as follows. [List name / Comment]: Displays a list of list names and their comments registered in the memory. The pages are displayed in the order in which they were registered. If the number of registered pages exceeds one page (30 pages), a plurality of pages are displayed. Switching between pages is performed by using the next page key 41 and the previous page key 40. [Number of list registrations]: Displays the number of lists registered in the memory. Next, the display fields on the list data input screen of FIG. 30 are as follows. [Number of materials]: Set the number of materials to be processed. [Continuous processing count]: Set the number of times of continuous processing. Setting 0 is equivalent to 1 time. [Reciprocating processing designation]: Sets whether to perform reciprocating (reverse) processing when processing. [Processing end position]: Set the processing end position. [NC program No.]: Set a program No. for conversion into a numerical control program. [Processing order / program name / processing table / mirror]: The program name, processing table number, and mirror processing in the order in which processing is performed. Symmetrical processing) is specified. To actually create a new operation list, press the new menu key 42 from the screen of FIG. 29, key in the list name and comment to be created in the installation section (comments can be omitted), and then enter the input key 3
Press 9. If the list name is not duplicated, the screen transits to the list data input screen of FIG. 30, and the list data is input. To edit the operation list, press the edit menu key 42 from the screen shown in FIG. 29, and the list name previously edited is displayed on the setting section. The list name to be edited is selected by the cursor movement key 37. Or input a key into the setting section, and then press the input key 39. If the list name is registered, the screen transits to the list data input screen in FIG. 28, and the list data is input.

(3-2) Operation Search Screen When the operation search menu key 42 is pressed, the color CRT 3 displays an operation search screen as shown in FIG. select.
The display fields on this operation search screen are as follows. [List name] (uppermost column): Displays the name of the list currently searched for operation. [List name / comment] (setting unit): Same as the operation list creation screen. [Number of list registrations]: Displays the number of lists registered in the memory. In order to actually perform the operation search, the user selects the list name to be searched with the cursor movement key 37 or key-in the setting section, and then presses the input key 39. CPU
11 starts a search, and the color CRT 3 displays a message being searched. When the entered list name is found, a search completion message is displayed, and the list name in the uppermost column is changed to the searched list name. Simultaneously with (or after) the operation search, the CPU 11 converts the inputted program included in the searched list name into a numerical control program in the EIA format, and stores it in the memory. At the time of this EIA format conversion or before the conversion, the following processing is added. a. In the case of sawing, the starting and ending points of the program input by the operator are
If the end point is set, correct machining cannot be obtained due to the saw having a certain size. Therefore, at the time of EIA format conversion, a correction value is calculated so that the start point and end point positions are correct, and automatic determination is performed. Specifically, as shown in FIG. 32, in the case of saw groove processing, the following start point position s0 and end point position e0 input by the operator are respectively described below.
The start point position s1 and the end point position e1 of the numerical control program displaced in the shortening direction by the correction value x represented by the equation (1) are automatically determined. Without this correction value x, the groove would be 2x longer than expected.

X = 2rd−d * d (1) where r: saw radius d: groove depth

As shown in FIG. 33, in the case of saw cutting, the starting point position s0 and the ending point position e input by the operator.
With respect to 0, the start point position s1 and the end point position e1 of the numerical control program displaced in the extension direction by the correction values xs and xe represented by the following equations (2) and (3) are automatically determined.
If the correction values xs and xe are not provided, the surface roughness of the cutting start / end portions is deteriorated, and the saw may be damaged.

Xs = r + c (2) where c: cutting start clearance

Xe = r + p (3) where, p: excessive cutting amount

B. Since the input order of the processing data on the program input screen is not always an appropriate processing order, the processing data is rearranged to the optimum processing order according to the following rule. (A) Sort each processing data from head information to end information according to processing mode. The order of the processing mode is
Saw cutting → Saw groove processing → Vertical boring processing → Horizontal boring processing → Router groove processing → Router hole processing. The order of the processing modes is the first priority. By this rearrangement, efficiency can be increased by reducing the number of times of tool switching at the time of machining. (B) In each processing mode of saw cutting, saw groove processing, router groove processing, and router hole processing, the processing data remains in the input order. (C) In the vertical boring processing mode, the processing data is rearranged in ascending order of the X-axis value. The judgment of the value of the X axis is not the position set by programming,
It depends on the position where the head 55 in FIG. 4 is actually moved. For this purpose, the reference position H of the head is calculated based on the following equation (4).
(Hx, hy) is obtained, and the processed data is rearranged in ascending order of hx. When hx is the same, the order of hy is larger. When hx = hy, it is left as it is.

H (hx, hy) = P (px, py) −L (lx, ly) (4) where H: reference position of the head P: setting position of vertical boring L: tool mounting position

(D) In the horizontal boring mode, the processing data is rearranged as follows. (D-1) First, the order of the plane of the material to be processed is as follows. A plane having the smallest (closest) distance from the vertical boring processing end position on the plane 0 among the planes 1, 2, 3, and 4 in FIG. 12 is selected (for example, the plane 2). When the distances are the same, the plane 1 is preferentially selected. Plane 0
The plane 1 is selected even when there is no vertical boring in. (D-2) Subsequently, the order of each plane is rearranged clockwise from the selected plane. For example, when the number of the selected planes is 2, the order is plane 2 → plane 3 → plane 4 → plane 1. (D-3) Rearrange in the order of the X axis or the Y axis for each plane. The order of rearrangement differs for each plane as follows. Plane 1: Ascending order of X-axis head reference position hx Plane 2: Order of increasing Y-axis head reference position hy Plane 3: Order of increasing X-axis head reference position hx Plane 4: Order of decreasing Y-axis head reference position hy c) By setting (d), it is possible to reduce the moving amount of the tool at the time of machining and increase the efficiency. c. The processing order between the materials is set so that the first processing is performed, for example, from the material W1 to the material W4, and then the next processing is performed so as to return from the material W4 to the material W1. The machining direction is selected closer to the position of the tool at the start of machining. This setting can also reduce the amount of movement of the tool during machining and increase efficiency.

(3-3) Operating state screen When the operating state menu key 42 is pressed, the color CRT 3 displays an operating state screen as shown in FIG. The display fields on this operation state screen are as follows. [Current position X, Y, Z, V]: The position currently being executed is enlarged and displayed with all axes and numerical values. The minimum unit is 10 μm. [Feed speed]: Displays the speed in the vector direction currently moving. [Tool No.]: Displays the currently selected tool No. [Processing table]: Processing tables 51 and 52, material W1
The state where .about.W8 is placed, the state of adsorption of the material to the processing table, and the processing state of the material are graphically displayed as operating state information 49. The graphic display specifications are as follows. At suction OFF: Processing tables 51 and 52 are painted in yellow. At suction ON: Processing tables 51 and 52 are painted in light blue. Material before processing: The material is only a white frame. Material in processing: The material is green painted. Material is painted in red [Processing count]: The cumulative value of the processing count (the value on the left) and the processing count value set in the operation list (the value on the right) are displayed.
When the processing of the materials W1 to W8 in both the left and right tables 51 and 52 is completed, the accumulated value is incremented by one.

(4) Parameter screen (4-1) Tool shape data screen When the parameter menu key 42 is pressed on the initial screen,
As shown in FIG. 35, since the color CRT 3 displays a tool shape data screen as one of the parameter screens, tool data is input.

In the above embodiment, the case where the machining tables 51 and 52 shown in FIG. 4 are driven simultaneously has been described. However, even when each of the machining tables 51 and 52 is driven independently, the programming of the present invention is executed in accordance with the above-described procedure. It is possible to Further, in the above-described embodiment, the case of the combined boring machine in which a plurality of tools are mounted on the head has been described.
