Geometric DFMPro 9.0.0.2301 for NXSeries

NX 2007 Series Support

Added New Rules

Composite Module

Minimum Distance Between Pocket to Panel Edge
Composite structure panels used in aerospace products have a higher strength-to-weight ratio. The minimum distance between cutouts, pockets, and panel edges should be maintained to avoid tearing composite panels. It could affect the load-carrying capacity of the panel and may result in damage during loading conditions. Maintaining a sufficient distance between the cutouts, pockets, and panel edges are always recommended


Minimum Distance Between Insert Hole to Panel Edge
Composite panels are strong and stiff with a higher strength to weight ratio, but their flexible cores are weak and easily damaged. When the insert holes are drilled too close to the panel edges or cutouts, there is a possibility of damaging the core area near the hole due to weak and minimum available core material. Due to this, inserts cannot be appropriately placed, and the core may get dislocated. This could affect the load-carrying capacity of the panel and may result in damage during certain loading conditions. Hence it is always recommended to provide some minimum distance between panel edge and insert holes. As a general guideline, the minimum distance should be 15 mm.

Recommendations: The general guideline suggests that the minimum distance between the insert hole to panel edge should be 15 mm.


Minimum Spacing Between Insert Holes
Composite structure panels used in aerospace products have a higher strength-to-weight ratio. But due to their weak core structure, they are not suited to withstand localized loads. Hence, inserts are used to transfer such localized loads to composite panels. Maintain enough spacing between insert holes to avoid the overcut problem.

Recommendations: The general guideline suggests that for the honeycomb panel, the minimum spacing should be 30 mm, and for the foam, it should be 20 mm


Composite - DFMPro Settings

Insert holes are identified through colors. Users can define colors code to identify Insert Hole or RGB values. It is a Global-level setting, and only the admin can define it.


Enhanced Existing Rule

Slot to Hole Alignment – Assembly Module

Gap between two Parts: Distance between faces of parts on which hole and slot are present.


Selection of “Ignore cases – hole axis and slot centerline is aligned” checkbox allows to ignore cases where the hole axis and slot centerline is aligned.


Added New Feature – Machining Setup (Mill Module)

Machining Setup

It provides an option to view and edit machining setups. Machining setups and their associated feature information would further help the design engineer optimize the design. Machining features are classified into different setups, and the design engineer can view setups with machining direction. With the button, features can be moved from one setup to other valid setups.



Cavity and Cavity Mold Type support

DFMPro provides an option to select mold type Core/Cavity and Cavity Cavity. Depending on mold type selection and pulling direction, mold faces are classified into two half – Cavity 1 and Cavity 2.
