Bridgeport Drill G-code

1 Import DXF / DWG

Drop a DXF or DWG here or browse… Circles (and circles inside blocks) become hole centres. DWG files are converted to DXF automatically.

2 Program setup

Work zero (0,0) Put 0,0 on the centre of a hole

0,0 from hole centre X Y

When unticked, the DXF origin is 0,0. When ticked, 0,0 is the chosen hole's centre plus the X/Y offset (leave both at 0 to use the centre). Every X/Y in the program, the table and the drill window is measured from there. Safe X/Y is too.

Safe start position (absolute) Safe X Safe Y Safe Z (knee)

Drill window Only drill holes inside this rectangle

Corner 1 X1 Y1 Corner 2 X2 Y2

A hole is used if its centre is inside the window. Anything outside is left out of the drill cycle.

3 Hole layout

Import a DXF to see the holes.

Scroll to zoom · drag to pan · drag a drill window corner to resize it · double-click to fit · click a hole to find it in the table. Dashed lines = drilling order for each size, returning to safe X/Y for each drill change.

4 Drill parameters (per hole)

Untick Drill to leave a hole out of the program. Only holes inside the drill window are listed.

Depth is a positive number measured from the axis zero; moves into the work are output as negative. To copy settings: set one row, click Use to make it the source, tick the holes to receive them, then press Copy source → ticked.
