Custom pockets
A custom pocket step must immediately follow a closed contour.
You can create a custom pocket from any closed contour. A closed 
contour is any shape consisting of lines, arcs, and/or blends (or 
chamfer), where the last step ends at the same point where the first 
step begins. MILLPWR

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 islands continuous tool 
path must appear first, followed by the Island step. Steps for the 
custom pockets continuous tool path must appear next, followed by

The percentage must be 50% or less. This is required to make sure 
that all material is removed.  
The pocket is machined at the feed rate programmed in the custom 
pocket step.  When the tool makes a cut greater than the step over, 
the full cut override is applied to the feed.  Depending on the 
complexity of the pocket, the tool will change feed as needed.  The 
full cut override only applies to the rough pass.  Bottom and side 
finish...

Advanced Custom Pocket Machining
Machining of custom pockets can be further enhanced using special 
cycles.  These optional steps apply specifically to the custom pocket 
and programmed after the custom pocket/island path.  In the program 
listing, they are shown as part of the custom pocket using dashed 
continuity lines.

Rough Milling
It is possible to rough mill a custom pocket with multiple tools, starting 
with a larger tool to remove large amounts of material quickly followed 
by smaller tools to remove material inaccessible to the previous tool.  
Each subsequent tool change and rough mill cycle only removes the 
material left by the previous coarse tool.
Rough milling is programmed after pilot drilling and before finishing 
operations.  If no finish steps...

Bottom Finishing
The Bottom Finish removes the material from the bottom of the 
custom pocket.
The Bottom Finish step must be programmed after the rough milling 
cycle(s) and before side finishing.  If no side finish step is programmed 
after the Bottom Finish step, the side finish operation is performed 
using the parameter settings in the custom pocket step.
