This document discusses several sheet metal forming processes including roll forming, drawing, peen forming, stamping, superplastic forming, and magnetic-pulse forming. Each process is suitable for different part geometries and has tradeoffs between production rates, tooling costs, and part complexity that can be formed. The document provides brief descriptions of the capabilities and limitations of each sheet metal forming technique.

METAL
FORMING

2. SHEET METAL FORMING
STEPS

3. ROLL
FORMING
Long parts with
constant complex
cross-sections; good
surface finish; high
production rates;
high tooling costs

4. Drawing
Shallow or deep
parts with
relatively simple
shapes; high
production rates;
high tooling and
equipment costs.

5. PEEN FORMING
Shallow contours on large
sheets; flexibility of
operation; equipment
costs can be high; process
is also used for
straightening parts.

6. Stamping
Includes a variety of
operations, such as
punching, blanking,
embossing, bending,
flanging, and coining; simple
or complex shapes formed at
high production rates;
tooling and equipment costs
can be high, but labor costs
are low.

7. Superplastic
forming
Complex shapes,
fine detail, and
close tolerances;
forming times are
long, and hence
production rates
are low; parts not
suitable for high-
temperature use.

8. MAGNETIC-
PULSE
FORMING
Shallow forming, bulging,
and embossing operations
on relatively low-strength
sheets; most suitable for
tubular shapes; high
production rates; requires
special tooling.
