When the curvature radius at a cutting point reaches a value in the range
specified by (Rlmt1) to (Rlmt5), an override is applied as described
below.
When Rlmt1 > Rcp " Rofs y Rlmt2
OVRb =
100 – OVR2
Rlmt1 – Rlmt2
(Rcp " Rofs – Rlmt2) + OVR2
When Rlmt2 > Rcp " Rofs y Rlmt3
OVRb =
OVR2 – OVR3
Rlmt2 – Rlmt3
(Rcp " Rofs – Rlmt3) + OVR3
When Rlmt3 > Rcp " Rofs y Rlmt4
OVRb =
OVR3 – OVR4
Rlmt3 – Rlmt4
(Rcp " Rofs – Rlmt4) + OVR4
When Rlmt4 > Rcp " Rofs y Rlmt5
OVRb =
OVR4 – OVR5
Rlmt4 – Rlmt5
(Rcp " Rofs – Rlmt5) + OVR5
Set Rlmt1 through Rlmt5 and OVR2 through OVR5 in parameter No.
5611 through No. 5615 and parameter No. 5616 through No. 5619,
respectively. Rcp " Rofs should read Rcp + Rofs for inside offsetting,
and should read Rcp – Rofs for outside offsetting.

If an override calculation finds an override value that is smaller than the
lower limit set in the parameter, the override value is clamped to the lower
limit.
