Stock Machining Enhancements

Further Improved Side Milling Operation Assignment for Neighboring Surfaces

In aPriori 2024 R1 SP2, improvements were made to the Parallel Surface Chain recognition released in 2024 R1, which in turn drive improved finish milling operation assignments.

In 2024 R1, aPriori introduced enhanced geometry recognition to identify chains of adjacent surfaces that are likely to be finished with the same side milling tool—see Improved Side Milling Operation Assignment for Neighboring Surfaces in the 2024 R1 aP Pro Release Notes for more details. The enhanced geometry recognition improved the ability of aPriori to identify a set of adjacent surfaces that a side-milling tool reasonably would be expected to follow in actual manufacturing practice.

In most cases, this enhancement led to improved operation assignment. However, in some instances aPriori incorrectly identified unsuitable surface chains that would not in practice be finished with the same side milling tool. Consequently, the recognition algorithm and the operation-assignment logic have been further refined to enhance the quality of chains identified by the model, further improving the credibility of aPriori analysis. The images below show an example of the refinements made in PSC recognition. The example shows a previously recognized, unsuitable chain that no longer is erroneously created in 2024 R1 SP2.

Previous Behavior (aPriori 2024 R1 & 2024 R1 SP1)		New Behavior (aPriori 2024 R1 SP2)
Two parallel surface chains were recognized within this pocket feature. The bottom of the pocket and the fillet should not have been identified as a surface chain for operation assignment, as these would not be side milled.		The improved algorithm successfully excludes the incorrect surface chain while retaining the valid chain for operation assignment.

Note: To access this improved functionality, you must use the latest cost model version for the Machining process group (CMV 320). In addition, you must use the latest cost model version for your primary process group, Stock Machining (CMV 210) or Multi-Spindle Machining (CMV 40).
