TN
FUNCTION: Tangent
DESCRIPTION:
The TN m,n command describes the tangent axis to the coordinated motion path. m is the
scale factor in counts/degree of the tangent axis. n is the absolute position of the tangent
axis where the tangent axis is aligned with zero degrees in the coordinated motion plane.
The tangent axis is specified with the VM n,m,p command where p is the tangent axis.
The tangent function is useful for cutting applications where a cutting tool must remain
tangent to the part.
ARGUMENTS: TN m,n
where
m is the scale factor in counts/degree, in the range between -127 and 127 with a fractional
resolution of 0.004
m = ? Returns the first position value for the tangent axis.
When operating with stepper motors, m is the scale factor in steps / degree
n is the absolute position at which the tangent angle is zero, in the range between +/-2

OPERAND USAGE:
_TN contains the first position value for the tangent axis. This allows the user to correctly
position the tangent axis before the motion begins.
