Basic Profile Milling

Profile milling sequences enable you to machine vertical and slanted surfaces. This is useful for machining the sidewalls of pockets and for machining outside profiles of components.
Profile Milling
• Machine vertical or slanted surfaces.
• Select or create final machining surfaces.
• Continuous toolpath required.
• Final cut depth determined by machined surface depth.
• Approach and exit moves.
• Material removal after completing NC sequence.
Customizing the Toolpath
• Modify default cut motions.
• Use approach/exit or tool motions.

• Alternative machining reference.
• Mill geometry.
• Create before or during creation of NC sequence.
• Common mill surface types:
– Fill
– Extrude
– Copy

You can use profile milling to rough or finish mill vertical or slanted surfaces.
You configure the final finishing surface by selecting reference model surfaces or creating mill surfaces. The following features describe profile milling NC sequences.
• Surfaces selected for machining must enable a continuous toolpath.
• The depth of the surfaces selected for machining determines the final cut depth.
• You can configure tool approach and exit motions.
• If you have a workpiece in the manufacturing model, you can remove the machined volume from the workpiece by creating a material removal feature. You can do this after you complete the NC sequence.
Customizing the Toolpath
• By default, toolpaths are generated based on the selected reference geometry and the manufacturing parameters.
• It is possible to modify these default cut motions by adding alternative approach and exit moves.
• You can use two tools to do this:
– Approach/Exit – This option enables you to add or remove slices or cutting passes, and specify approach and exit paths.
– Tool Motions – This option enables you to modify default cut motions.
This includes removing default cut motions and adding your own cut motions including approach and exit tool motions.
– Both tools provide essentially the same functionality, but use different interfaces.
Using Mill Surfaces for Profile Milling
When creating profile milling sequences, you can use mill geometry such as mill surfaces as alternative machining references when model surfaces are not appropriate. As an example, you can do this when you profile mill a model surface that has a variable depth.
• Mill surfaces are surface features and are often referred to as mill geometry.
(The other mill geometry features are mill volumes and mill windows.)
• You can create mill surfaces before creating an NC sequence, or during the creation of an NC sequence.
• The most common mill surface types are:
– Fill – Use the fill tool to create a flat surface by sketching an outline on a sketching plane.
– Extrude – Create an extruded surface by sketching an outline on a sketching plane.
– Copy – Copy existing model surfaces to form a new mill surface.
