G68
* Stock removal cycle along X axis.
G68 X Z C [D] [L] [M] [J] [K] [F] [H] S E P Q
X: X coordinate of the profile's starting point
Z: Z coordinate of the profile's starting point
C: Machining pass (in radius)
D: Withdrawal distance after each pass
D=0: the tool exit path is the same as the
entry path. D<>0: retracts at 45 degrees; D
not programmed: retracts while following the
profile to the previous step
L: Finishing stock on the X axis (in radius)
M: Finishing stock on the Z axis (If not
programmed, it will be that indicated for
parameter L)
J: Maximum travel in each section on the
machining axis
K: Penetration feedrate in the roots
F: Feedrate for the last roughing pass. If not
programmed or programmed as F0, it does
not run the last roughing pass.
H: Finishing feedrate. If not programmed or
programmed as H0, it does not run the
finishing pass.
S: Label number of the first block describing the
geometry of the profile
E: Label number of the last block describing the
geometry of the profile
P: Number of the subroutine where that defines
the profile
Q: Name of the global subroutine, that contains the
definition of the profile (parameters E and S) or
of the program that contains the local subroutine
that contains the profile (parameter P)
