An Example in Steel Casting    The Ice Cleat on the M1 Abrams Tank

Machining Features

Designing for Machining Features

The ice cleat has  a requirement for two features that have to be machined.    
These features are --

  • A shouldered hole in the center body  through which the mounting bolt passes.  There is sufficient stock in the body for the hole.  No design features have to be changed in the casting.
  • Three flat studs on the back face which act as locating pads for the ice cleat in the track shoe.

Original Design

To provide enough metal stock for final machining of the flat studs, bosses are added to the design.   These bosses are approximately 3/8" thick.
