FIG. 12 shows an axis version setting screen.

The screen includes a coordinate system screen 121 and other item 1
With 22 settings, the screen is divided into two screens. The coordinate system screen 121 is visually represented and can be set directly by numerical values and a mouse.

The setting using the mouse is as follows: (1) Axis version selection (input of numerical value and selection of number on the figure) (2) Approximate position of version origin is set. (Displayed at the cursor coordinates.)
Version origin and reference pin can be set directly.
The reference pin can be set arbitrarily on the printed circuit board.

Other items 122 display cursor coordinates, total origin, floating origin, floating origin correction, and version origin. The X coordinate and the Y coordinate are arranged horizontally.

Regarding the Axis Version The Axis version changes the coordinate system, and determines the origin position of the changed coordinate value (version coordinate system) as the version origin. The offset value of the version coordinate system, that is, the value of the version origin is set in the item of “version origin”. The following version coordinate system can be selected by setting the Axis Version item.

When the version origin set value (origin shift amount) is "0", the version coordinate origins are all located on the machine coordinate origin.

The floating origin is used when moving the machining origin. When machining with a part program created on a machine with a different sub-table size, the distance between the machine origin and the reference pin differs depending on the size of the sub-table, so the machining origin must be shifted from the machine origin. Occurs. This floating amount is set at the floating origin.

In the floating origin correction, the floating origin is moved by the amount of the set value (correction value). In the floating origin correction, the set value can be changed even during machining.

The floating origin and the floating origin correction are determined by the parameter (F
ORG), a coordinate system can be selected.

FORG 0: Floating origin and floating origin correction are set in the machine coordinate system 1: Floating origin and floating origin correction are set in the version coordinate system The processing origin in FORM = 0 is set based on the machine origin. , Version origin, floating origin, and floating origin correction. On the other hand, FORG =
The processing origin in 1 is obtained as the sum of the setting values of the setting item, the floating origin, and the floating origin correction based on the version origin obtained by the setting value of the setting item and the version origin.

The total origin is displayed by finally calculating the total shift amount based on the floating origin, the floating origin correction, and the version origin.

As described above, the drill management device forms a printed circuit board screen, sets a version origin setting item for setting the origin position of the coordinate system to the version origin, and a reference arbitrarily defined on the printed circuit board screen. A floating origin setting item that is set to shift the machining origin from the version origin with reference to the distance between the pin and the version origin,
The floating origin correction value setting item set for moving the floating origin by the set value and the total origin display item for displaying the version origin, the floating origin, and the amount of shift depending on the floating origin correction value as the total origin are printed. It is configured to include a screen processing device for forming and displaying in parallel with the substrate screen.

A method of punching a printed circuit board for sequentially processing a plurality of predetermined positions on a printed circuit board is to form a printed circuit board screen, set the origin position of the coordinate system to the version origin, and arbitrarily set reference pins on the printed circuit board screen. A floating origin is set to shift the machining origin from the version origin by referring to the distance from the version origin, and a floating original correction value is set to move the floating origin by a set value. The amount of shift depending on the floating origin correction value is displayed on the screen as the total origin.

FIG. 13 shows an emergency stop screen.

When an abnormality occurs during the operation and the apparatus is automatically stopped, an emergency stop screen shown in FIG. 13 is displayed. As shown in the figure, a coping method display 131 and an emergency stop display 132
Is displayed on the screen, a "cause display", a "response method display", and a "restart method display" are displayed. The cause is displayed using specific terms as well as error codes. In the response method, a specific position and a response method are displayed in a diagram, a photograph, or the like.

A restart button 133 is arranged at the bottom of the screen.
