In addition, as shown in Fig. 5, when inputting coordinate values, the absolute coordinates X 1 and Y are set with the specified origin position as (0, 0). There are two types of input, absolute value input with 1 and increment value input with the previously input coordinate value (XI, Y 1) or increment value '1 or V1. The range value of the coordinate value data is checked in two ways: when setting the data and when selecting the program check. Whether the set coordinate value ≤ the material dimensions, the absolute coordinate conversion data material Check whether the dimensions are correct (so that the input data of the increment value can be checked correctly).

b.Head (head) information input (Fig. 4 1 st e P 3)

As shown in FIG. 11, the input of a new program starts with the head mode, which is the head mode. The input items are as follows.

Pressing the operation search menu key 4 2 causes the color CRT 3 to display the operation search screen as shown in Fig. 34. From this screen, press the operation list creation menu key 4 2 Transition to Create Screen "

(3-1) Operation list creation screen

Pressing the operation list creation menu key 4 2 causes the color CRT 3 to display the 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. 30. First, each display in the screen of FIG. 29 is as follows.

[List name. Comment]: Displays the list name and its comment registered in the memory. The pages are displayed in the order in which they were registered. If the number of registered pages exceeds 1 page (30 pages), multiple pages will be displayed. To switch pages, use the next page key 41 and the previous page key 40.

Key 3 9 If the list name is registered, the screen changes to the list data input screen shown in Fig. 28, where the list data is input.

(3-2) Operation search screen

Pressing the menu key 4 2 of the driving search, the color C R T as shown in Figure 31

3 displays the operation search screen, and searches and selects the list name for automatic operation on this screen. Each displayed palm in this driving search screen is as follows _u

[List name] (top column): Displays the name of the currently searched operation list, [List name · Comment] (Setting section): Same as the operation list creation screen

[List registration :! : Displays the number of lists registered in the memory. To actually perform an operation search, key in the force setting section to select the list name to be searched using the cursor movement keys 37, and then press the input key 39. CPU 11 starts the search, and color CRT 3 displays the message being searched. When the entered list name is found, a search completion message is displayed, and the top list name changes to the searched list name. '

Simultaneously with (or after) the operation search, the CPU 11 converts the input program included in the searched list name into an EIA-format numerical control program and stores it in the memory. At the time of this EIA format conversion or before conversion, the following processing is added.

a. In the case of sawing, if the start and end points of the program entered by the operator are left as the start and end points of the numerical control program, correct machining can be obtained because the saw has a certain size. Therefore, when converting to EIA format, calculate the correction value so that the start point ■ end point position is correct, and perform automatic determination. ,, In the case of saw cutting, as shown in Fig. 32 , The starting point input by the operator ^ s 0 • The start point position s 1 and the end point position e 1 of the numerical control program displaced in the direction of “end point position e 0 in the direction of shortening by the correction value X represented by the following equation (1)” are automatically determined. Without this correction value X, the groove would be 2X longer than expected.

x = 2 r d-d * d · · · (]) where r: saw radius

d: depth

As shown in FIG. 33, in the case of saw cutting, the start position s 0 input by the operator and the end position e 0 are corrected by the following equations (2) and (3), respectively. The start position s 1 'end point position el of the numerical control program displaced in the extension direction by the values xs and X e is automatically determined. _Without these correction values xs and _xe , the surface roughness at the start and end of cutting will be poor, and the saw may be damaged.

X S = Γ + C (2) where, C: Cutting start clearance

X e = r + p (3) where, P: excessive cutting amount b. Since the input order of machining data on the program input screen is not always an appropriate addition order, the machining data is Rearrange to the optimal processing order according to the rules.

(a) Sort each processing data from head information to end information by processing mode. The order of machining mode is saw cutting, sawing, vertical boring, horizontal boring, router drilling, and router drilling. The order of this processing mode is the first priority. By this rearrangement, the number of times of tool switching during machining can be reduced and efficiency can be increased.

(b) In each of the machining modes of saw cutting, saw groove machining, router machining, and router hole machining, machining data is kept in the input order.

(c) In the vertical boring mode, the machining data is Rearrange them in order. The determination of the X-axis value is not based on the position set by programming, but on the position where the head 55 in FIG. 4 is actually moved. For this purpose, the reference position H (hx, hy) of the head is determined based on the following equation (4), and the processed data is rearranged in ascending order of hx. When hx is the same, the order of hy is large. If hx = hy, leave it as it is.

H (h x, h y) = P (p x, p y) —L (l x, 1 y)

• · ■ (4) Where, H: Reference position of head

P: Vertical boring setting position

L: Tool mounting position

(d) In the horizontal boring mode, the machining data is rearranged as follows.

(d-1) First, the order of the planes of the material to be processed is as follows: Of the planes 1, 2, 3, and 4 in Fig. 12, the distance from the vertical boring processing end position on the plane is the smallest ( Select a plane that is close (for example, plane 2) If the distances are the same, select plane 1 preferentially Plane 1 is selected even when there is no vertical boring on plane 0.

(d-2) Then, rearrange the order of each plane clockwise from the selected plane. For example, if the selected plane is 2, plane 2 → plane 3—plane 4—plane.

(d-3) Rearrange in the order of X axis or Y axis for each plane. The order of rearrangement differs for each plane as follows.

Plane 1: X axis head reference position hx in ascending order

Plane 2: Y-axis head reference position h, in descending order of y

Plane 3: X axis head reference position hx in descending order

Plane 4: Smallest order of y-axis head reference position h y

By setting (c) and (d) above, it is possible to reduce the amount of tool movement during machining and increase efficiency. c. Regarding the processing order between the materials, it is set so that the first processing is performed, for example, from material W1 to material 材 W4, and then the next processing is performed so as to return from material W4 to material W1. The machining direction is selected closer to the position of the tool at the start of machining. Even with this setting, it is possible to increase the efficiency by reducing the amount of tool movement during machining ₍ . (3-3) Operation status screen
