8.7.3 Irregular Island

Press the IRREG ISLAND key if you wish to mill an island other than a rectangle or

circle. The Irregular Island gives you the powerful Auto Geometry Engine to define a

shape made up of straight lines and arcs.

The first screen in an Irregular Island event will define the beginning point and some of

its general parameters. The last event of the irregular island must end at the same point

as defined in the first event.

Prompts for the Irregular Island event:

X BEGIN: X dimension to the beginning of the island.

Y BEGIN: Y dimension to the beginning of the island.

Z END: is the Z dimension at the bottom of the pocket; incremental is from the previous

event

#PASSES: the number of roughing passes to the depth

ENTRY MODE: choose between zigzag ramp and plunge. The plunge will machine

straight down Z to the appropriate Z depth. The zigzag ramp will move in a zigzag

pattern to depth. See the previous section for more information about the zigzag ramp.
