Semi-Finish Machining
Effective semi-finishing is the key to successful finish machining. A uniform
amount of stock must be present to assure the constant chip load required for high quality surface finishes
and to facilitate additional machining wth smaller cutter tools.
FF/cam can Generate Toolpaths That Match Geometry Enabling Uniform Stock Removal for Finish MachiningIn addition to to knowing precisely how much stock remains and what individual cutting tools can do relative
their geometry for a given the part, machine tool and material; FF/cam offers a wide variety of machining strategies to
assure a consistant amount of stock is available for finish machining operations.
Corner Machining
Corner areas left uncut in the
rough machining process are removed to supress tool chatter in finish machining operations. Users have a wide variety
of toolpath strategies to choose from with complete control over extry/exit moves, cutting direction and all pertenient cutting parameters.
These strategies include:
- Uncut Corner Areas are Machined
- While Keeping the Tool Load Constant
- Machining is Done Along a Corner
- Area Producing a Natural Continuity
- Between Adjacent Faces, Eliminating
- Irregular Load Changes When Finishing
Avoiding Un-Cut Stock
FF/cam's Contour Gap Machining and Contour Projection Machining functions
are perfect for assuring constant stock in all areas of the part.
With Contour Gap Machining, toolpaths are generated only in areas that are un-cut; even
in areas with shallow slope angles where "step-like" uncut portions are
likely to appear from a previous constant-z type rough cutting operation.
FF/cam's Contour Projection Machining Strategy is the optimal machining method for matching workpiece geomethry.
This strategy automatically choosed the correct cutting style based on geometry, such as contour machining
for vertical surfaces and scan machining for flat surfaces.
