Details: Changes to Baselines that DO NOT affect Customer VPEs
The following changes are available in the aPriori Baseline VPEs only. If you wish to take advantage of these new capabilities, the VPE needs to be upgraded to the most recent Cost Model version. Please contact your VPE Admin or aPriori Account Manager to plan work.
• New External Broaching Operation: This release introduces the operation External AxiGroove Broaching for linear broaching of a rotationally-symmetric pattern of features, such as the fir-tree or dovetail root joint features commonly found on turbine and compressor disks. In previous releases, Hobbing was typically assigned to such features. In this release, the new external broaching operation is assigned instead, provided that both the following hold:
o The feature is undercut, rendering it infeasible for Hobbing (that is, the geometric property radialUndercutVolumeRatio is greater than 0).
o The geometry can be generated by extruding the tooth/valley profile in a straight direction (that is, the geometric property isStraighExtrude is true).
Depending on feature geometry, this can sometimes increase or decrease costs, compared to the previous release.
