Fundamental Manufacturing Processes (DVD)
This DVD from SME's Fundamental Manufacturing Processing series examines the basic materials, tools, and techniques of tubular hydroforming and sheet metal hydroforming.
Hydroforming, unlike conventional sheet metal stamping processes, uses fluid pressure applied to a blank to form the desired component shape. The advantages of hydroforming include single setup operations, reduced part count and possibly part weight, and lower scrap rates.
In this 23-minute program, detailed animations and shop floor footage explain the three primary types of tubular hydroforming techniques: low-pressure, high-pressure, and pressure sequencing hydroforming.
The use of in-process hydro-piercing and the importance of lubricants also are presented. The sheet metal hydroforming section covers rubber diaphragm forming and active hydro-mechanical drawing.
The various secondary operations performed on hydroforming parts, such as additional holemaking, part trimming, and joining operations, conclude the DVD.
