Sinumerik G63 Tapping with floating tapholder
This cnc programming tutorial shows that cnc machinists have another option for tapping on cnc machine which don’t have pulse generator.
Sinumerik G63 is used for tapping with floating tapholder.
For Sinumerik G63 function cnc machinist need a tap in the floating tapholder. A pulse generator is not needed for the spindle.
Sinumerik G63 Programming Format
Sinumerik G63 Tapping with floating tapholder
N10 G63 Z-50 M3 S...F... N20 G63 Z4 M4 F...
Z – Depth in Z-axis
S – Spindle speed
F – Feedrate (F = Spindle speed x Thread lead)
M3 – Direction of rotation right
M4 – Direction of rotation left
Retraction
For the retraction movement, you program another block with G63 and the relevant direction of spindle rotation.
Feedrate Calculation
F = Spindle speed x Thread lead
