Feed Rate Control Improvements
SmartCAM v2018 Feed Rate Control Improvements
Feed rate control has been expanded with several technical changes that provide better and more complete control of toolpath feed rates.
Additional Rough and Face Milling Operation Feeds
The Rough and Face Milling operations have been enhanced to include new Fast Feed settings and a Conventional Cut Feed Factor.
SmartCAM engineers can now property-change the feed rate type of individual elements or groups of elements to use the available feed rate entity types. In addition the Fast Feed and Conventional Feed Factor are automatically used by the new Adaptive Roughing processes that have become available in the Advanced and FreeForm Milling products and milling in Advanced Turning. The Fast Feed specifies a high feed rate for return moves, when unidirectional cutting. The Conventional Cut Feed Factor specifies a factor used to reduce the default Primary Feed feed rate for conventional cuts, when bidirectional cutting.
Additionally, the previous Plunge Feed has been renamed to Slow Feed, continues to be used for plunge moves, but now is also used for process ramp and helix entry moves.
Property Change Feed Entity
The Toolpath Property Change function has been enhanced to include a new Feed Entity Type which allows specific toolpath entity types to be assigned to a group of toolpath elements, available in SmartCAM Milling and Turning applications. The Feed Entity types include Primary Path, Ramp, and Fast Return, and is used to establish the default feed rate.
Primary Path uses Primary Feed, Ramp uses Slow Feed, and Fast Return uses Fast Feed. This capability allows you to manually build toolpath that uses the same feed rate mechanisms as toolpath generated by process panels.
Property Change Feed Override
A new Feed Override option can be used to apply a feed rate change directly to a group of elements. This assigned feed rate attribute overrides all other feed rate mechanisms; such as the default value from the Operation or using a Feed rate user command. This now equips you with even more precise control over the feed rates and feed rate changes that you need to use.
The feed rate can be assigned as unit rates, per-rev, per-minute, and per-tooth; or as a multiplication factor. When using the unit feed rates, the units you enter are stored; when generating code the units are converted to the feed type selected for the given step.
Element Data Feed Information
The Element Data function has been enhanced to display additional information related to element feed rates. When applicable, the element type will now include the Feed Entity Type, for example Ramp or Fast Return.
When an element Feed Override is used, Element Data displays the related Feed information on a new line. It shows the Override type (per-tooth, per-minute, per-rev, factored) and the entered rate. It also displays the updated feed rate and the feed type selected for output.
Machine Events Feed Change
The user command-based Feed Change functionality has been replaced with the same feed attribute-based capabilities that have been added to Toolpath Property Change.
You can now select a group of elements and apply the desired feed change. Existing Feed Change hot-keys and toolbar buttons will open the new Feed Change panel.
