CAMWorks provides two different methods of creating a
โPart Perimeterโ feature to remove material from the outside
of your part. These methods are the โOpen Pocketโ and โBossโ types.
Part Perimeter type โOpen Pocketโ should be used when itโs
intended to remove all material up to the selected geometry.
This should be used when there is a significant amount of material to remove
from the stock, and multiple parts are not being cut out of a single piece
(such as a sheet). This is the typical method you will be using when machining
parts from bar stock.
โOpen Pocketโ Type Part Perimeter Feature
Part Perimeter type โBossโ should be used when itโs intended
to follow the outside profile with one or several passes.
This is appropriate to use as a Part Perimeter for applications such as
routers, where it is intended to plunge down and cut out just the outside
profile of the part. It may also be appropriately used to โclean upโ parts
such as castings or partially machined parts that need only slight material
removal.
โBossโ Type Part Perimeter Feature
This concept is extended to CAMWorks โOpen Pocketโ and โBossโ features. Unlike
the โPart Perimeterโ feature which only applies to the outside profile of the
part, the โOpen Pocketโ and โBossโ features allow you to machine areas
internal to the geometry.
The โBossโ feature, when applied to an internal boss as
pictured below, allows you to chase the profile of the boss.
This would allow cleaning up of a castingโs critical surfaces or other
geometry, but โBossโ features are not what you would typically want to use for
mass material removal.
โBossโ Feature
The โOpen Pocketโ feature on the other hand, as pictured
below,
allows for automatic removal of all material to a certain depth. It automatically detects any islands (internal features that protrude above
that depth) and intelligently machines around them. This means that you can
very quickly program material removal around multiple features, simply by
selecting the bottom face and applying an โOpen Pocketโ feature.
