Cost Model Changes that don't Affect Configured Digital Factories

The following changes do not affect costings with Digital Factories that use earlier cost model versions. The changes are available only in the latest cost model version.

  • Automated Deburr Number of Operators (impacts labor time and cost): This release reduces the number of operators for the Automated Deburr process from 1 to 0.5, to reflect the fact that a single operator typically monitors two machines simultaneously. As a result, labor time and cost for this process decrease by 50%, compared to the previous release.

  • Surface Deburring (can impact cycle time): In the previous release, when Automated Deburr or Manual Deburr were included in the routing and Include Automated Surface Deburr or Include Manual Surface Deburr was set to true, deburring operations were assigned to both surfaces and edges. In this release, when these setup options are set to true, deburring operations are assigned only to surfaces, since surface deburring removes burrs from the surface's edges as well as from its interior. As a result, when the options are set to true, deburr times and costs decrease compared to the previous release.

    Note:

    If you update to the newest version of the Machining cost model (CMV 260), there is an impact on scenarios that were created in earlier releases of aPriori and include Edge Deburring operations. If these scenarios are re-cost in the latest cost model version, the Edge Deburring operations will no longer be present. The recommended workflow is to re-assign Edge Deburring operations to the desired edges and re-cost again.

  • Chipmaking Time for Hole-making Operations (can impact cycle time): In the previous release, for hole-making operations on blind holes, the chipmaking time was the time required to traverse the length of the hole plus the length of the tool tip, even when the hole-bottom was modeled as flat and the setup option Hole Bottom Geometry Interpretation was set to Literal. In this release, for a blind hole with the hole-bottom modeled as flat and the setup option Hole Bottom Geometry Interpretation set to Literal, chipmaking time is the time required to traverse just the length of the hole. As a result, for such holes, cycle times may decrease slightly.
