Re: Syntax for Bridgeport Boss 6 canned cycle?

Hello,

From an original manual:
Bolt Circles are Programmed using the following format:
G V1 A n1 A n2 Z V2 F V3
where V1 - The canned Z axis cycle parameter (G81)
n1 - The polar coordinates of the LAST point to be drilled,
incrementally from the first or absolute from the polar
axis.
n2 - The signed incremental angle between points.
V2 - The canned Z axis parameter distance or distances.
V3 - The Z axis feedrate.
NOTES: 1. Polar Coordinate Data cannot be Transformed i.e. Rotated
or Scaled (G73).
2. Cannot be used with Cutter Diameter Compensation.

The manual was the M-104 from 2/1/80.
I hope this helps?
I have never tried this, so good luck.
