2. MECHANICAL ENGINEERING SENIOR DESIGN PROJECT
Abstract:
Wendell August Forge, est. 1923, is one of America’s oldest and finest metalcrafters. One of their most beloved
products is their hand-designed annual Christmas ornament. With the popularity of this product, Wendell August
desired to produce a higher volume of these ornaments and charged senior Grove City College mechanical engi-
neers with designing an automated hammering prototype to be used as the basis for a future production machine.
Building off of the single-ornament hammering unit created by the previous year, the second-year team solved addi-
tional automation challenges by developing four key systems: the feeding, punching, clamping, and linkage sys-
tems.

Clamping
The clamping system holds the sheet firmly to the die as
each ornament is hammered. It is actuated by a pneumatic cyl-
inder that engages the clamp after the feeding system releases
the sheet. This permits the alignment table to move the material
to the correct locations for hammering and stamping.
Feeding
Aluminum stock (thickness: 0.090”) is roll-fed into the
machine via a nip roller system. The bottom roller is made of
precision-ground steel and driven by an Aerotech servomo-
tor. A pneumatic cylinder moves the upper, urethane roller
vertically to engage or disengage the system depending on
the state of the other operations. When engaged, the system
precisely feeds stock into the machine.
Linkage
Wendell August Forge desired for the project to operate
without exceeding excessive noise levels - i.e. run in an office-
like environment. The crank and toggle system was
developed to provide the necessary forces while remaining
quiet and efficient. The hammer block was designed to
include an offset stamp for impressing the Wendell August
Forge logo into the back of each ornament after hammering.
Punching
Indexing each hammered ornament is crucial to locating
the ornament in subsequent operations. A 4 1/2” pneumatic
cylinder actuates a punch that creates a 1/4” index hole for
each ornament as the stock feeds through. These index holes
align with pins on the die and will also be used for blanking
operations in the future.
