Technical Reference
Types of Sheet Metal Operations
The sheet metal fabrication process is built from a set of core sheet metal operations — each serving a distinct purpose in the fabrication process. There are two primary categories: cutting operations (blanking, piercing, punching, notching, shearing) and forming operations (bending, deep drawing, embossing, beading). Understanding types of sheet metal operations helps OEM engineers specify the right process for each feature — and Aero Enterprises performs all 8 in-house at our Vasai sheet metal workshop. See a complete breakdown with definitions, sheet metal operations with diagrams-style descriptions, and machine specs below.
Blanking
Sheet metal blanking punches a complete flat shape from the parent sheet — the punched piece is the required blank. Used for consistent flat-profile preparation before any forming operation.
Piercing
Piercing in sheet metal cuts holes through the blank — the punched-out slug is waste. Piercing operation in sheet metal is performed simultaneously with blanking in compound dies for efficiency.
Punching
Punching operation in sheet metal removes material to create holes, slots, or notches. Punching process in sheet metal uses a punch and die set on our 10T–150T sheet metal punching machine range.
Notching
Notching in sheet metal removes corner or edge material to allow clean sheet metal folding and bending without material collision — critical for sheet metal box and enclosure corner joints.
Bending / Folding
Bending operation in sheet metal forms angular profiles. Sheet metal folding on CNC press brake to ±0.5°. Types of sheet metal bends produced: air bending, bottoming, coining, V-bending, and wipe bending.
Deep Drawing
Deep drawing sheet metal forms flat blanks into cups, boxes, and enclosures. Drawing operation in sheet metal used for LED housing shells, driver compartment bodies, and deep-drawn enclosure components.
Embossing
Sheet metal embossing creates raised or recessed features. Embossing operation in sheet metal and embossing process in sheet metal are used for stiffening ribs, identification marks, and surface texture.
Beading
Beading in sheet metal forms a rounded bead or rib along the surface to increase rigidity without adding thickness. Common in sheet metal enclosure, panel, and frame stiffening applications.

CNC Bending Technical Reference
Sheet Metal Bending — Calculation, Formula & Bend Allowance
Sheet metal bending calculation determines the correct flat blank length before bending. The standard sheet metal bending formula uses Bend Allowance (BA) — the arc length of the neutral axis through the bent zone. Correct sheet metal bending calculation prevents under-sized or over-sized blanks that cause assembly failures. Our engineers verify minimum bend radius sheet metal compliance per material grade before every CNC job.
What is Bend Allowance in Sheet Metal?
Bend Allowance (BA) is the length of the neutral axis arc through the bend zone. It must be added to the flat blank dimensions to get the correct developed length. What is bend allowance in sheet metal? — it compensates for material stretching at the outer bend radius.
Sheet Metal Bending Formula
BA = A × (π ÷ 180) × (R + K × T)
A = Bend angle (degrees) | R = Inside bend radius (mm)
K = K-factor (0.33 to 0.50) | T = Material thickness (mm)
K-factor range: 0.33 (sharp bend) → 0.50 (neutral axis centred)

- CNC Press Brake 100T / 3100mm — Primary bending tool
- Manual Press Brake 6.5ft × 2 — Secondary folding

Minimum Bend Radius Sheet Metal — Per Grade Reference
| Material Grade | Min Bend Radius | K-Factor | Density of Sheet Metal | Notes |
|---|---|---|---|---|
| CR IS 513 | 1 × T | 0.33 | 7.85 g/cm³ | Best for precision bends — low springback |
| HR IS 2062 | 2 × T | 0.42 | 7.85 g/cm³ | Scale surface — wider radii recommended |
| GI IS 277 | 1.5 × T | 0.38 | 7.85 g/cm³ | Avoid tight radius — zinc coat cracks |
| SS 304 | 1 × T | 0.38 | 7.93 g/cm³ | Higher springback — must over-bend to compensate |
| Aluminium 5052 | 0.5 × T | 0.33 | 2.70 g/cm³ | Lowest springback — lightest sheet metal |
| Brass C260 | 1 × T | 0.38 | 8.50 g/cm³ | Ductile — clean bend edges, no delamination |
Types of Sheet Metal Bends
Air Bending
Punch contacts material, die provides clearance. Springback must be compensated. Most common CNC press brake operation — used for most standard angle bends across all sheet metal grades.
Bottoming
Punch presses material fully to die bottom. More accurate than air bending with reduced springback. Standard sheet metal bending tool setup for tight tolerance work.
Coining
Maximum tonnage — material flows into die cavity. Highest accuracy, least springback. Used for precision sheet metal bending where final angle accuracy is critical.
V-Bending
Most standard CNC press brake setup. V-die and punch. Applied across all material grades and thickness ranges in sheet metal folding and bending operations.
Wipe Bending
Material is wiped over die edge. Fast for simple flanges and sheet metal folding on thin gauge 0.5mm–1.5mm material where speed matters.
Roll Bending
Used for large-radius bends and curves on structural channels — sheet metal bending tools include a 3-roll bender for architectural and structural profiles.

Sheet Metal Material Properties & Grade Reference
Sheet metal material properties — tensile strength, yield strength, and density of sheet metal — determine which grade to specify for each fabrication operation. Steel sheet metal (HR IS 2062, CR IS 513) covers most fabrication needs. Corrugated galvanized sheet metal (GI IS 277) handles outdoor corrosion environments. Sheet metal properties like density of metal sheet are critical for weight calculations in automotive and solar tracker applications. All grades below are available at Aero Enterprises Vasai.

Sheet Metal Enclosure
Fabricated sheet metal enclosure bodies for electrical panels, LED driver housings, control boxes, and industrial cabinets. Processes: laser cut → notch → bend → weld → powder coat. Supplied to drawing with dimensional report.
Sheet Metal Box
Deep-drawn and CNC-bent sheet metal box assemblies for instrument enclosures, storage trays, and structural containers. Sheet metal box corners are notched before bending for clean right-angle joints without material overlap.
Clamp Sheet Metal
