It is also known as reverse tapping cycle and counter tapping cycle.



Parameter of left hand peck tapping cycle :-

XY- XY position where operation will perform .
Z - Operation perform depth .
Q - Depth of each cut .
R - R plane position .
F - Cutting feed rate
G74 and G84 cycle are used for tapping operation but difference is G74 is used for left hand tapping and G84 is used for right hand tapping .

FEED RATE CALCULATION


F= RPM X Pitch
