Island
An island is a raised area (e.g. a boss) within a custom pocket that
remains after material has been removed from around all of its sides.
Though islands are easy to program, they must be placed correctly
within the program sequence. Steps for the island's continuous tool
path must appear first, followed by the Island step. Steps for the
custom pocket's continuous tool path must appear next, followed by
the Custom Pocket step. You may program more than one island
within the Custom Pocket.
To program an island:
Program a closed contour for the island.
From the PGM screen, place the cursor below the last step of the
island’s closed contour.
Press the Program Steps soft key.
Press the Custom Pocket soft key.
Select Island in the popup Menu.
Check that the first and last steps listed in the step range match the
first and last steps for the island’s continuous tool path. If they’re
correct, press the USE key; if they’re not, press the CANCEL key and
check that the closed contour for the island is correct and/or the
correct step has been highlighted.
Tool Path Description for Custom Pocket, and Islands
Machining of the custom pocket begins at a location based on
pocket geometry. The software automatically determines this
location.
The tool ramps into the material at the Z feed rate.
The CW/CCW direction of roughing passes is determined by the
direction of the profile formed by the custom pocket.
The XY step size is determined by the system and will not exceed
the specified percentage of the tool diameter.
The percentage must be 50% or less. This is required to make sure
that all material is removed.
The Z step size is determined by the system and will not exceed the
specified distance or number of passes.
The tool retracts to the active datum's retract position between Z
passes.
A finish allowance is optional but recommended. If specified, this
amount is left on the bottom and sides of the pocket and islands to
be removed on the finish pass.
When the finish feed is 0, the finish pass will be skipped. The tool
retracts to the active datum's retract height and the specified
"staging" position between rough, bottom finish, and side finish
operations.
A Custom Pocket will include all Islands that are within the
custom pocket reguardless of which step has been
selected when the GO key is pressed.
