nose radius compensation in fanuc tb-mate

[rags]

hello,
we are face grooving profile grooves on aluminium castings, we have taken co-ordinate points for the profile from the Autocad drawing,we face a problem of radii at different points in the groove measuring either in excess or reduced to the extent of tool nose radius of 0.4mm when compared to the drawing which is attached with this message

any suggestions
thanks
