point.
Note 5
:
The tapping cut decelerates to stop when the system resets, emergently stops or the drive unit
alarms. The spindle is in the course of stopping rotation but Z has stopped feed, which maybe
damage the workpiece and screw tap. So, do not force to stop G84/G88.
Note 6
:
N0.5209#0=0, i.e. drilling axis is selected by the levels in rigid tapping mode”. When G17, G18, G19
is separately specified in G84, the drilling axes separately correspond to the basic axis X, Z, Y;
when G17, G18, G19 is separately specified in G88, the drilling axes separately correspond to the
basic axis Y, X, Z.
Program example: machining thread M10×2 is shown below:
G98
;
feed per minute
G0 X0 Z200
;
X and Z position to the starting point
M3 S800
;
the spindle rotates (CW) at the speed 800 r/min. the spindle
starts rotation after the block is executed.
G84 Z160 P1000 F1600
;
starting point is X0 Z200
,
which is same as the hole position
,
;
hole bottom position is X0 Z160, and the pause time is 1s
,
;
the thread lead is 2 according to F and S value.
;
G84 is the common tapping cycle when it is not specified in
advance.
;
the spindle stops rotation after the block execution ends.
G80
;
Fixed cycle is cancelled
