Calculating Cutting Speeds • Cutting speeds (CS) are given is feet per minute. • Work speed is given in revolutions per minute (RPM). • Speed of work must be converted to RPM. • RPM = CS X 4/D • D = diameter of workpiece • CS = Cutting speed of particular metal
Lathe Attachments • Threading attachment • Taper attachment • Steady rest and follower rest attachments
