Abstract
An earthmoving machine comprises an implement. The implement defines a variable implement angle θBucket(t) indicative of a current position of the implement relative to horizontal as a function of time t. The implement comprises teeth extending a tooth height h and defining an active raking ratio r. Controllers are programmed to execute an implement teeth grading offset determination process that comprises determining a variable implement offset angle θDelta(t) at least partially based on a difference between an original target design angle θTgt(t) and the variable implement angle θBucket(t), determining an implement offset IO based on h, r, and θDelta(t), and determining a new target design elevation ElvTgt,New(t) based on IO and an original target design elevation ElvTgt,Orig(t).
