Powder Metal Through the Process Steps
The article "Powder Metal Through the Process Steps" appeared in the September/October 2018 issue of Gear Technology.
Powder metal (PM) gears normally sell due to the lower cost and their relatively high mechanical performance. The reason behind the lower cost is that most of the machining is omitted due to the net-shape forming process. So how net-shape are powder metal gears? In this article some hard-to-find information about the tolerances through the manufacturing steps will be presented.
