N100 TRAILON(V,Y)
Activate 1st combined axis pair
N110 TRAILON(W,Z,–1)
Activate 2nd combined axis pair, coupling
factor negative: trailing axis traverses in
opposite direction to leading axis
N120 G0 Z10
Infeed of Z and W axes in opposite axis
directions
N130 G0 Y20
Infeed of Y and V axes in same axis
directions
…
N200 G1 Y22 V25 F200
Superimpose dependent and independent
movement of trailing axis "V"
…
TRAILOF(V,Y)
Deactivate 1st coupled axis
TRAILOF(W,Z)
Deactivate 2nd coupled axis
