Description

This book describes different types of rubber-pad forming processes currently being studied for their experimental and numerical advantages and disadvantages. Rubber forming adopts a rubber pad contained in a rigid box in which one of the tools (die or punch) is replaced by the rubber pad. Up to 60% of all sheet metal parts in aircraft industry such as frames, seat parts, ribs, windows and doors are fabricated using rubber-pad forming processes. Key process parameters such as rubber material, stamping velocity, rubber-pad hardness and thickness and friction conditions are investigated.

Key Features

  • The potential role of rubber as a flexible punch in metal working processes is to give insight to engineers about different parts that can be produced using this process
  • The procedure of suitable die design for each process is presented in detail
  • Full defect analysis is undertaken with a thorough report presented to optimize rubber-pad forming processes

Readership

Mechanical, industrial, and manufacturing engineers and students, process engineers and product design engineers.
