Threading Cycle

Threading Cycle. Threading requires multiple passes in perfect synchronization to reach final thread depth. Must make sure you are in constant spindle speed mode, not constant surface speed!. Computing Thread Parameters. Overall thread height H = Pitch*(0.5 / tan 30deg) = 0.866025*Pitch
