Methodology
Surface Machining is a versatile application, fully adapted to your needs and your
working methods whether they are machining area-oriented or operation-oriented. You
can either define the machining areas on your part and then assign an operation to each
of them or you can define your machining process as a series of operations with an area
to machine for each operation.
A machining area can be:
the whole part (for example, in roughing),
a subset of the faces on the part,
a subset of faces on the part with a limiting contour.
The Getting Started chapter contains two sections, one which demonstrates
operation-oriented machining and another which demonstrates area-oriented machining.
Before starting work with Surface Machining, please ensure that you have an open file
(CATPart or CATProduct) and that you are in the Surface Machining workbench (Start >
NC Manufacturing > Surface Machining).
Here is a suggested order for operations in a machining program:
rough machining operations,
(semi-)finishing operations,
detection of unmachined areas,
reworking of unmachined areas,
generation and output of documentation.
Area-oriented
Area-oriented methodology is useful when you have a complex part
to machine and you know in advance what kind of operation you are
going to apply to each separate area.
This approach is of great use when, for example, you are going to
machine a "family" of similar parts and when you have dedicated
machines for mass production.
You define the areas on one part, you assign an operation to each
area, and then you machine. At the end you have a program that you
can apply to all of the "members" of the "family" at least working cost
because:
the machining strategy has already been defined (chosen
operations),
the tool has already been defined,
only the area need be redefined,
