Drill Bolt Hole Cycle
Use the drill bolt hole cycle to drill a partial or full bolt circle. A drill
cycle must be programmed prior to the bolt hole cycle. You can
move around the pattern clockwise or counterclockwise, either
point to point or along a radius. The cycle calculates the hole
locations, and uses the Polar Coordinate System for dimensions.

Description
Diameter
D
Diameter of bolt circle. Tool normally
moves from hole to hole in a CCW (positive)
direction. For CW direction, D = negative.
(Required)
moves from hole to hole in a CCW (positive)
direction. For CW direction, D = negative.
(Required)
StartAngle
A
Angle of the first hole. (Required)
#Holes
H
Number of holes in full bolt circle.

RadialPath
R
Move from hole to hole on a radius. Set to
1.0 to activate circular path between holes.
Defaults to straight-line path between
holes.
