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.
• Material Cost and Scrap Credit: In previous releases, the cost model always assumed that material scrap (for example, trim scrap) and part scrap (material from scrapped parts) was not sold for credit. In this release, the same assumption is made by default in starting point VPEs, but VPE administrators can enable scrap credit by default with the cost model variables enableScrapMaterialCredit and enableScrapPartCredit. In addition, users can override the default on a per-part basis with the setup options Enable Scrap Material Credit and Enable Scrap Part Credit.
If material scrap credit and/or part scrap credit is enabled, utilization increases and material cost decreases. Part scrap credit includes credit for parts scrapped by this process as well as by downstream processes. The credit rate is specified as a percentage of the material rate by the material property Scrap Cost Percent.
• Tooling Cost and Tool Life: In previous releases, tooling cost calculations assumed that a single tool lasts long enough to produce the production volume specified in any scenario. In this release, the cost model estimates the number of parts that can be produced with a given tool before it wears to the point that it needs to be replaced. Based on that estimate, the cost model determines the number of tools required to manufacture the specified production volume, and accounts for that number of tools in total hard tooling cost.
Tool life is accounted for in the tooling cost calculations for the following processes:
o Hydroform
o Offline Blanking
Tool-life estimation is based on part material, tool material, and tool coating type. For a given costing, either the formula Dependencies or Investment tab displays the number of tools assumed by tooling cost calculations.
With default production volumes (5,500 parts annually for 5 years), hard tooling cost is not affected by this change, as only one tool is required. With production volumes that require multiple tools, hard tooling cost increases compared to previous releases.
• Improved Estimation of Tool Coating and Heat Treatment Costs: this release includes improved data for tool material density, tool material unit cost, and tool coating unit cost. As a result, hard tooling cost has been observed to increase an average of 5%-10%, compared to previous releases.
