G60 Exact Stop Mode
Format
N... G60
A block will be worked off after the slides have been
decelerated to standstill.
Edges will not be rounded and transititions will be
exact.
G60 is active until it will be cancelled by G62 or G64.
G62, G64 Deselection Exact Stop

Format
N... G62/64
Before the target point in X is reached, the Z axis will
be accelerated. This enables steady movements.
The contour transitition is not exactly sharp-edged
(parabola, hyperbola).
With this software G62 and G64 have the same
effect, but not with the SINUMERIK 810/820 T.

Format
G63 X.. Z.. F.. S..
Thread tapping without synchronisation.
The spindle speed is programmed under the address
S and a suitable feedrate underthe address F.
G63 is effective blockwise. While G63 the feed and
spindle override are locked to 100%.
The retraction movement (with opposite spindle di-
rection) also must be programmed with G63.
Example:
Tap M5 (pitch P = 0,8 mm)
spindle speed S = 200, therefore F = 160
