Why It Matters
A substantial growth can cause loss of fit in the end-use assembly, or unwanted vibration and/or performance.
What You Can Do
Spinning rough forgings to achieve a specified amount of plastic pre-growth before final machining is a well-established method to produce the highest quality and dimensionally stable parts.
