Carbon Estimates for All Standard Machining Operations

aPriori 2024 R1 now provides carbon emissions estimates for all standard machining operations***. These estimates account for the carbon emissions due to the energy required for the machine’s spindle to remove material from the workpiece.

aPriori 2024 R1 now provides carbon emissions estimates for all standard machining operations***. These estimates account for the carbon emissions due to the energy required for the machine’s spindle to remove material from the workpiece. Previously aPriori provided CO2e estimates for many primary machining operations but not for all standard operations and secondary machining processes. In cases where machining operations were included that did not provide carbon estimates, aPriori alerted the user via the Sustainability tab, and indicated the percentage of total process cycle time from operations that neglected carbon estimates.

Processes which newly-provide complete operation coverage for carbon emissions estimates in aPriori 2024 R1 include:

  • 2 Axis Bar Feed Lathe with Sub Spindle

  • 2 Axis Lathe

  • 3 Axis Bar Feed Lathe with Sub Spindle

  • 3 Axis Lathe

  • 3 Axis Mill

  • 3 Axis Router

  • 4 Axis Mill

  • 5 Axis Mill

  • 5 Axis Router

  • Automated Deburr

  • Bevel Gear Cutting Machine

  • Broach

  • Cylindrical Grinder

  • Deep Bore Machine

  • Drill Press

  • Gun Drill

  • Hob Machine

  • Inspection

  • Internal Grinder

  • Jig Bore

  • Jig Grind

  • Manual Deburr

  • MillTurn

  • Perimeter Cut

  • Profile Gear Grinder

  • Reciprocating Surface Grinder

  • Rotary Surface Grinder

  • Shaper

  • Shaver

  • Special Inspection

  • Spline Roller

  • Stock Prep Lathe

  • Stock Prep Mill

  • Threaded Wheel Gear Grinder

  • Wire EDM

 

*** Carbon emissions estimates still are not provided for Chemical Milling operations or for Multi-spindle Machining processes (CNC Multi-Spindle and CNC Turning Center machines).

BOM Loader Support for Sustainability Data

In aP Pro 2024 R1 the BOM Loader module was extended to support loading of sustainability data.

The following fields now can be populated by the BOM Loader:

  • Material Carbon: the carbon attributed to the raw material required to manufacture the component

  • Electricity Process Carbon: the carbon attributed to the electricity required by the used in the processes used to be able to manufacture the component

  • Other Process Carbon: The process carbon attributed to any secondary sources. This includes sources of carbon not related to electricity to manufacture the component.

  • Consumable Process Carbon: The process carbon attributed to any consumable materials required in the processes used to be able to manufacture the component

  • Logistics Carbon: the carbon attributed to the logistics process used to be able to manufacture the component

For more information on using the BOM Loader, refer to the section BOM Loader in version 2024 R1 of the Digital Factory Administration Guide.

Notification for Missing Material Carbon Emissions Factor

In aPriori 2024 R1, customers who are licensed for aPriori’s Sustainability module now will be alerted if material property data required to calculate the part’s Material Carbon is not populated.

Now when a user costs a part with a material that has no value for the relevant carbon emissions factor, the part fails to cost. In aP Pro, a failure message is displayed in the Messages window. Users can address the missing factor in two ways:

  • On a per-scenario basis: enter a value for the Primary Material Carbon Factor in the Part Details tab.

  • At the deployment level: enter value(s) for the relevant material carbon factor field(s) in the Materials table in the Digital Factory.

Note that the materials in aPriori’s Regional Data Libraries all include material carbon emissions factor values, however materials added to customer digital factories previously may be missing these fields.

Calculate Energy Consumption when Computed Overhead Rate is False

aPriori 2024 R1 resolves a previous issue in which energy consumption estimates were not computed for customer Digital Factories that used custom overhead rates.

Prior to aP Pro 2024 R1, process direct and indirect energy consumption erroneously were not calculated for configured Digital Factories that use custom overhead rates instead of aPriori’s computed overhead rates. (Note that for processes in the Machining process group, direct energy will always be calculated.) This issue has been corrected, and now both direct and indirect energy consumption are always calculated and included in process carbon estimates, regardless of overhead methodology. Customers who use custom overhead rates and have not configured the model to calculate energy consumption should expect to see an increase in their total carbon emissions.

Note: A cost model version upgrade or backport is necessary to receive this fix; if your company is licensed for Sustainability and uses custom overhead rates, please contact your aPriori account team to determine how to proceed.
