Troubleshooting
It's an error if:
l Inverse time feed rate mode is active and a line with
G01, G02, or G03 (explicitly or implicitly) does not have
an F word
l A new feed rate is not specified after switching to G94
or G95 canned cycle return level – G98 and G99
10.2.26 Spindle Control Mode (G96 and G97)
To set constant surface speed mode, program: G96 D~ S~
l D~ is the maximum spindle RPM.
This word is optional.
l S~ is the surface speed.
Note: If G20 is the active mode, the value is
interpreted as feet per minute. If G21 is the
active mode, the value is interpreted as meters
per minute
E X A M P L E
G96 D2500 S250 (set constant surface speed
with a maximum RPM of 2500, and a surface
speed of 250).
When using G96 (the most common mode of machine
operation), X0 in the current coordinate system (including
offsets and tool lengths) must be the spindle axis.
To set RPM mode, program: G97
Troubleshooting
It's an error if:
l S is not specified with G96
l A feed move is specified in G96 mode while the spindle
is not turning

All canned cycles are performed with respect to the active
plane. The descriptions we use assume the XY-plane has been
selected. The behavior is always analogous if the YZ- or XZ-
plane is selected.
l X~ is the X-axis coordinate
l Y~ is the Y-axis coordinate
l Z~ is the Z-axis coordinate
l A~ is the A-axis coordinate
l R~ is the retract position along the axis perpendicular to
the currently selected plane (Z-axis for XY-plane, X-axis
for YZ-plane, Y-axis for XZ-plane)
l L~ is the L number is optional and represents the
number of repeats
All canned cycles use X, Y, Z, and R words. The R word sets the
retract position; this is along the axis perpendicular to the
currently selected plane (Z-axis for XY-plane, X-axis for YZ-
plane, Y-axis for XZ-plane). Some canned cycles use additional
arguments.
Rotational axis (A-axis) words are allowed in canned cycles,
but it's better to omit them. If rotational axis words are used,
