QUESTION:What type of tool material should an operator use when machining a ductile metal?POSSIBLE ANSWERS:Cubic boron nitride (CBN)DiamondHigh-speed steel (HSS)Ceramic
Solution
The operator should use High-speed steel (HSS) when machining a ductile metal. This is because HSS is tough and has the ability to withstand the forces involved in machining ductile metals. It also retains its hardness at high temperatures which is often generated when machining metals.
