Geometric DFMPro 10.0.0.4521 for Siemens NX 2212 Series

Added New Rules

Maximum Print Size – Additive Manufacturing
In Additive Manufacturing, it is essential to know the component's overall dimension (print size) to check whether it fits properly on the machine bed and can be printed. Appropriate component sizes that fit on the machine bed will avoid delays in manufacturing and reduce extra costs.Users can configure the maximum print size values depending on the sub-process or default print size independent of the sub-process.


Minimum Wall Thickness – Additive Manufacturing
Based on the Additive Manufacturing sub-process, minimum wall thickness should be maintained for supported and non-supported walls. Thin walls are more likely to warp due to differential shrinkage during the cooling process. It bends before the resin can dry or cure. Extra support is required to hold it.
- Fusion Deposition Modeling (FDM) – Minimum Wall Thickness should be 0.8 mm for supported and non-supported walls.
- Stereolithography (SLA) - Minimum Wall Thickness should be 0.5 mm for supported and 1.0 mm for non-supported walls.
- Selective Laser Sintering (SLS) - Minimum Wall Thickness should be 0.7 mm for the supported wall.
Users can configure the manufacturing process like Fusion Deposition Modeling, Stereolithography, Selective Laser Sintering, and corresponding minimum wall thickness values for supported and non-supported walls.


Recommended Text Parameters – Additive Manufacturing
Text characters are small features in additive parts that convey additional information.
Example:
- Lettering
- Identification marks
- Important instruction, warning
- Legal and Regularity information
- Company logo, Symbols
Text characters are small features of an additive part and look much better if raised above the print's surface. Text height and width should be visible above the print's surface. If it is too small, then during printing, it might fuse with the model.Users can configure the manufacturing process like Fusion Deposition Modeling, Stereolithography, Selective Laser Sintering, and corresponding Recommended Text Parameters (text height and width).


Axial Misalignment Between Cored and Machined Hole - Milling
In the case of assembly machining, the pre-machined stock is used as a reference component, and machined features (drilled holes) are created on top of the stock. Rule checks the axial misalignment between cored hole (present in the cast link body) and the machined drill hole. Axial misalignment between cored and the machined hole creates an assembly issue.


Minimum Thread Relief Based on Thread Size - Drilling
While threading a blind hole, sufficient relief should be provided at the bottom of the threaded hole. Enough relief clearance allows for chamfer teeth of the tap; it will keep the tap tool from bottoming out in a hole and avoid any overcut issue while threading.


NX Check-Mate - DFMPro Settings

By default, the Update results in Check-Mate after import option is selected and is used to update the Checkmate results after successfully importing DFMPro results. To stop updating results in checkmate after import, deselect the checkbox.It is a global-level setting, and the admin can only define it. For non-admin users, this setting will be disabled.


User Inputs - Additive Manufacturing Sub Process

Users can select the sub-process option in the User Inputs group box only when Additive Manufacturing is selected as a Manufacturing Process to execute the analysis. There are four types of sub-processes: Default, FDM (Fusion Deposition Modeling), SLS (Selective Laser Sintering), and SLA (Stereolithography). DFMPro will analyze the Additive Manufacturing rules and specific sub-process rules based on the selection.


Manual Check Functionality

DFMPro Manual Check functionality will provide a framework to execute non-CAD geometryspecific checks, e.g., drawing-related checks, standard regularity checks, template-related checks, etc. After configuring those checks in standard “DFMPro_Manual_Check.xlsx,” all checks are available as a separate rule in the rule file. The designer can select those rules and perform DFMPro analysis. DFMPro will display a Manual Check dialog box during execution where the user can select the check that indicates the user has performed it.


Rule Manager - New User Interface

DFMPro has introduced a Rule Manager - New User Interface for a better user experience.

Additive Manufacturing
Users will be able to create additive manufacturing rules like Minimum Wall Thickness, Maximum Print Size, and Recommended Text parameters based on the following features and parameters:


Rule Summary and Rule Description
Describe rule application and importance in the form of a Summary. DFMPro will automatically fill in default information based on the Rule name. Users can modify it as required. A few special characters are not supported in the rule summary, like: ”, l, :, \\, ?, *
For example, if the rule name is Minimum Clearance Hole Diameter, DFMPro will fill the default summary as “Minimum Clearance Hole Diameter as per configured value in UI.”
