Adaptive feed support for 3-axis, 3+2-axis, and 5-axis HSM roughing in Creo

Creo now supports adaptive feed rate control within HSM roughing sequences, allowing feed rates to be automatically adjusted during machining.
User Interface Location: In a manufacturing assembly, edit the definition of a roughing sequence, and then on the parameters list, set the ADAPTIVE_FEED_CONTROL parameter to YES and define the MIN_ADAPTIVE_FEED parameter value.

Release: Creo Parametric 9.0.0.0

What is the benefit of this enhancement?
This capability helps optimize feed rates in HSM Rough and Rest-Rough sequences to better utilize the capabilities of CNC machines. It removes the limitation of relying on a single fixed feed rate that is typically constrained by sharp corners in the toolpath.

With adaptive feed enabled, feed rates are reduced in corner regions for 3-axis, 3+2-axis, and 5-axis HSM Rough and Rest-Rough sequences. The algorithm dynamically adjusts the feed rate based on tool engagement in the material, and a single tool move can be divided into multiple segments with different feed values. For the Constant Load scan type, the impact is reduced since it already maintains consistent tool engagement.

Overall, this enhancement improves tool life, minimizes chatter, enables high-end CNC machines to run more efficiently, and helps lower-end machines better manage high-performance toolpaths.
