Sheet Metal Design Flashcards

What does the K-Factor represent in SolidWorks sheet metal design?

Answer: The ratio of the neutral axis location to the material thickness

The K-Factor is the ratio of the neutral axis distance (from the inner bend surface) to the total material thickness, used to calculate accurate flat pattern dimensions.

Which SolidWorks sheet metal feature creates the first and foundational geometry of a sheet metal part?

Answer: Base Flange/Tab

The Base Flange/Tab feature creates the initial sheet metal body from a sketch, establishing the starting geometry for all subsequent sheet metal features.

What does the Flat Pattern feature in SolidWorks sheet metal represent?

Answer: The unfolded 2D layout of the formed part showing cut shape before bending

The Flat Pattern is the unfolded 2D representation of the sheet metal part showing the actual shape to be cut from flat stock prior to forming.

In SolidWorks sheet metal, what is Bend Allowance?

Answer: The arc length of material consumed within the bend zone

Bend Allowance is the arc length of material in the bend zone that is used when calculating the flat pattern stretched length of the part.

Which SolidWorks sheet metal feature creates continuous flanges that transition at mitered corners?

Answer: Miter Flange

The Miter Flange feature creates a series of flanges along multiple edges with automatically mitered corners, producing a clean fit at angle transitions.

What is the primary purpose of Relief cuts in sheet metal bend design?

Answer: To prevent tearing or distortion of material at the ends of a flange

Relief cuts are added at flange terminations to prevent the material from tearing or puckering when the sheet is bent into its final form.

Which SolidWorks commands allow you to selectively open specific bends to add features on flat faces, then re-close them?

Answer: Unfold / Fold

The Unfold and Fold commands let you selectively unbend specific bend zones, add features to the now-flat face, and then fold the part back to its formed state.

What is the purpose of a Hem feature in SolidWorks sheet metal?

Answer: To fold an edge back on itself to eliminate sharp edges and add stiffness

A Hem folds the edge of a sheet metal part back onto itself, eliminating the sharp cut edge and adding stiffness along the part boundary.

Which SolidWorks sheet metal feature creates a step-like Z-shaped offset in a flange?

Answer: Jog

The Jog feature creates a two-bend offset (Z-profile) in a sheet metal flange, allowing a face to transition to a parallel plane at a different elevation.

What is the function of Forming Tools in SolidWorks sheet metal?

Answer: To add stamped features such as louvers, lances, ribs, and dimples

Forming Tools are library-based solid bodies that simulate press-die operations, adding embossed features like louvers, lances, and dimples to sheet metal parts.

What does the Bend Deduction method calculate in sheet metal flat pattern development?

Answer: The amount subtracted from the sum of flange lengths to yield the flat pattern length

Bend Deduction is subtracted from the total length of the unbent flanges to determine the correct flat pattern length, compensating for material behavior at the bend.

What is a Lofted Bend feature in SolidWorks sheet metal?

Answer: A feature that creates a transition between two dissimilar open sketch profiles

A Lofted Bend creates a sheet metal transition body between two open profiles on separate planes, commonly used for rectangular-to-round duct transitions.

What does Corner Relief do in SolidWorks sheet metal?

Answer: Prevents material overlap or tearing at the intersection of two converging bends

Corner Relief cuts material at the junction where two bends meet, preventing the material from distorting or overlapping when both flanges are formed.

Which SolidWorks command is the primary method for converting an imported thin-walled solid body into an editable sheet metal part?

Answer: Convert to Sheet Metal

Convert to Sheet Metal allows you to select a thin solid shell, specify bend edges and sheet metal parameters, and convert it into a parametric sheet metal part with full flat pattern capability.
