aPriori Professional 2022 R1 SP1 provides several enhancements that improve Deburring process estimates and a warning for the inappropriate selection of Plate-Stock Roughing Techniques.
Improved Deburr Estimates
Obtain more accurate and reliable Deburring process estimates.
These three enhancements improve the accuracy and reliability of Deburr estimates:
-
The Number of Operators for the Automated Deburr process was reduced from 1 to 0.5, to reflect that a single operator typically monitors two machines simultaneously. Labor time and cost for this process will reduce by 50% as a result.
-
Edge Deburring operations no longer are assigned when the user selects Surface Deburring for the Automated or and Manual Deburr processes.
By default, when either the Automated Deburring or Manual Deburring process is included, only Edge Deburring is assumed so each edge on the part is assigned an Edge Deburring Operation. To indicate that Surface Deburring is desired, users can use the Include Automated Surface Deburr and Include Manual Surface Deburr process setup options. Previously, this caused both Surface Deburring operations and Edge Deburring operations to be assigned to all surfaces and edges of the part, respectively. In actual manufacturing practice it is not necessary to separately deburr edges, because surface deburring removes burrs from the edges of surfaces as well as their interiors. In the previous release aPriori Professional over-estimated deburring cycle time and cost. In aPriori Professional 2022 R1 SP1, Edge Deburring operations are no longer assigned when the Surface Deburr option is chosen, reducing Deburr times and costs.
-
aPriori Professional 2022 R1 SP1 provides greater flexibility and reliability when assigning Edge Treatment operations. It now is possible to assign either or both Edge Machining operations (such as Chamfering) and Edge Deburring operations to a given edge. Previously these were alternatives and could not be assigned together. Additionally, this change has resolved some previous errors in which an Edge Deburring operation failed to cost and provided an unclear error message.
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 no longer will be present. The recommended workflow is to re-assign Edge Deburring operations to the desired edges and re-cost in aPriori Professional 2022 R1 SP1.
Warning for Inappropriate Selection of Plate-Stock Roughing Techniques
Ensure stock form is set to Plate stock, for perimeter milling and perimeter cutting roughing techniques.
aPriori now alerts users if the workpiece stock form is not compatible with the chosen roughing technique.
As in previous releases, the Stock Machining process group provides a process setup option Roughing Technique for Plate Stock which provides three options for rough milling of plate stock workpieces:
-
All Bulk Milling: all material removed by roughing is converted to chips.
-
Perimeter Milling with Dropoff: enables perimeter cutting as a 3-axis mill, 4-axis mill, or 5-axis mill operation.
-
Plate Cutting with Dropoff: enables perimeter cutting using a waterjet, plasma, oxyfuel, or laser cutting operation
The second and third options have an impact only if the part's stock form is set to Plate Stock. In previous releases, the user was not warned if a different stock form was selected and could be unaware that the desired roughing technique had not been applied. In aPriori Professional 2022 R1 SP1, the part will fail to cost if a non-plate stock form is selected when either Perimeter Milling or Plate Cutting techniques are chosen, so that the user is alerted and can override the stock form as needed.
