Effect of the Forming Zone Length on Helical Rolling Processes for Manufacturing Steel Balls

This paper begins with a brief overview of the methods for producing balls. It then discusses the rolling processes for producing balls in helical passes. Next, a method for designing tools for helical rolling (HR) is described. Six different cases of rolling using tools with helical passes of diffe...
