aPriori Professional 2022 R1 SP1 provides this enhancement for the process group:
Design Guidance for Sheet Metal - Roll Forming
Obtain Design for Manufacturability (DFM) and Design to Cost (DTC) guidance for parts made by the process.
aPriori Professional now provides Design Guidance for the Sheet Metal - Roll Forming manufacturing process model, which was introduced in release 2022 R1. aPriori Professional alerts users to multiple different conditions that can reduce manufacturability or increase the cost of manufacturing, including but not limited to:
-
Minimum Bend Radius – If a bend radius is too small, cracking can occur.
-
Minimum Bend Flap Length – It can be difficult or infeasible to form the flap or flange adjacent to a bend that it is too short.
-
Insufficient Spacing between Holes/Cutouts – If holes and cutouts are located too close together, the thin strip of material between them can deform or fail.
-
Insufficient Spacing between Holes and Part Edges – If a hole is located too close to the edge of the part, the thin strip of material the hole and the edge can deform or fail.
-
Insufficient Spacing between Holes and Bends – If a bend is located too close to a pre-punched hole, the hole can be distorted.
-
Excessive Cross Section Height – Parts with very tall cross sections are susceptible to end flaring after a cutoff operation or unintended scoring on part.
-
Inaccessible Bends – Bends that are not accessible because they are obscured by subsequent bends cannot be supported by rollers and may lead to lower achievable tolerances or other quality issues.
-
Maximum Spacing Between Bends – Excessive distance between adjacent bends can lead to waviness of the land surface between them.
-
Minimum Spacing Between Bends – Insufficient distance between adjacent bends may make it difficult to achieve the specified bend radii.
-
Cross Section Symmetry – Parts with non-symmetric cross sections may require straightening, which drives up cost.
