Sheet Metal – Stretch Forming¶
Cost impact for upgrades to aPriori Professional 2021 R1
Cost Model Version Summary¶
The following table shows the cost model version numbers for the last three major releases:
| Release | Cost Model Version | Status |
|---|---|---|
| aPriori 2021 R1 | 70 | New with this release |
| aPriori2020 R1 | 50 (29.1.0) / 60 (20.1.1) | From a prior release |
| aPriori 2019 R2 | 30 (19.2.0) / 40 (19.2.1) | From a prior release |
Summary of Platform Changes¶
The table below indicates whether there were geometry and/or cost engine changes for this process group. Such changes could impact costing results for configured Digital Factories.
| Platform Area | Was there a Change? |
|---|---|
| Geometry | Yes |
| Cost Engine | No |
Change Summary by Area¶
The table below indicates whether there were geometry and/or cost engine changes for this process group. Such changes could impact costing results for configured Digital Factories. For the first type of change (geometry or cost engine changes), the table indicates the impact level (High, Medium, Low, or No).
| Area | Impact? |
|---|---|
| Geometry or cost engine changes that could impact configured Digital Factories | LOW |
| Bug fixes or small improvements to prior cost model versions that could Impact configured Digital Factories | NO |
| Cost model changes that do not affect configured Digital Factories | NO |
Details: Geometry or Cost Engine Changes that Could Impact Configured Digital Factories¶
The following changes might impact costing, even for Digital Factories that use earlier cost model versions.
- Blank Size (Potential Impact: Material Cost and Machining Time): Previously, in rare cases, aPriori underestimated blank thickness, length, or width, because it did not recognize certain areas that are reduced in thickness due to material removal (typically by machining or chemical milling). No GCD was extracted for such an area, so no time and cost for the corresponding material removal operation was accounted for and no indication of an uncosted GCD was provided to the user.
In this release, aPriori better recognizes areas of reduced thickness, and extracts distinct GCDs for them. Each such GCD is either assigned an appropriate operation or is extracted as a NotSupported GCD whose Cause property is Different Thickness. As a result of this change, times and costs (including material cost) may increase for some parts.
Details: Bug Fixes or Small Improvements to Prior Cost Model Versions¶
The following changes might impact costing for Digital Factories that use earlier cost model versions.
- NO IMPACT
Details: Cost Model Changes that Do Not 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.
- NO IMPACT
