Undercut depth (radius) (default: value from standard
table)
K Undercut length (default: value from standard table)
R Undercut radius (default: value from standard table)
W Undercut angle (default: value from standard table)
P Face depth (default: value from standard table)

Undercuts can be programmed only between two linear
elements. One of the two linear elements must be parallel
to the X axis.
