6.8.3 RIGID TAPPING (G84, G80)
With function G84, it is possible to tap a part by interpolating the spindle rotation with
the movement of the axis.
The machine must have an X axis and a servo-controlled spindle (with servo-drive
and spindle encoder).
The spindle feedback is connected to input A2 and the analog output for the spindle
is provided at pins 34 and 35 of connector I/O1.
When the machine has a rigid tapping axis Y cannot be used. If you wish to use an electronic
handwheel this must be connected to pins 17 and 25 of connector I/O2
Nevertheless, the CNC uses the Y function to define the thread pitch. Consequently,
machine parameter "P60(8)" must be set to "0" to enable this function
P63(3)=1 The machine uses rigid tapping.
P60(8)=0 Enable the Y function.
P77 Number of spindle encoder pulses.
Its programming format is: G84 X Y F S
X Defines the depth of the tap.
Y Defines the tapping pitch.
When assigning a positive value, it must be defined in turns/mm or turns/
inch. and when assigning a negative value, in mm/turn or inches/turn.
F Defines the tap-in speed in rpm.
S Defines the tap-out speed in rpm.
If parameter "F" is programmed and not the "S" parameter, the tap-in and tap-out
movements are performed at the same speed, the one indicated by parameter "F".
If parameters "F" and "S" are not programmed, the CNC assumes the values used
on the previous tap. If no tapping operation was performed previously, the CNC
will issue the corresponding error.
Parameters "F" and "S" are reset to "0" on power-up, after an Emergency or a
Reset.
