Abstract

The disclosure is directed to the use of forging tools and machine parts by employing a method and structure in the form of a negative draft angle and larger positive draft angle to form tongue or groove elements in the tools and machine parts as forged from the dies. Employment of the negative draft angle with a greater positive draft angle permits tools and machine parts to be formed so that the metal being worked is formed with a continuous uncut and uninterrupted grain flow extending longitudinally of the working member being formed. A negative draft angle of substantially 5 degrees when used with a positive draft of substantially more than 5 degrees has been found to produce excellent results.
