Aerospace Precision Forging Processes and Technology C1347

The advancement of forging technologies and processes has enabled the increased use of forged products to meet the demanding requirements of strength, durability, and reliability. While forgings are commonly used in aerospace manufacturing, the ability to make use of precision forging processes and techniques is critical when manufacturing gas turbine components. Realizing the benefits of accuracy and quality that precision forging brings to product manufacturing requires those involved with design and manufacturing have an understanding of industry accepted technology and processes.

This three day seminar will introduce participants to the precision forging processes and technologies currently in use in industry. The instructor will begin with an overview of the benefits of precision forging and the various manufacturing industries that currently make use of this approach. The instructor will discuss equipment, processes, and quality control requirements. Using examples derived from gas turbine engine rotor blade and vane manufacturing, the attendees will then be presented with the technical requirements to set-up precision forging and the various special processes. The instructor will also provide attendees with the information required to analyze customer drawings, key parameters, raw material requirements, and forging press selection.
