https://forums.autodesk.com/t5/hsm-forum/cant-get-simulation-to-profile-x-contour-in-fursion360-turning/m-p/6090161#M17144 I frequently use "multi-tools" for ID boring/plunging then reverse the spindle to machine the OD with the same tool.  Both ID and OD cuts with the same tool can be roughing or finish profiling operations--both require back turning (undercutting) on occasion.
