Abstract: A method for autonomously grinding a workpiece includes: accessing a virtual model defining a geometry of the workpiece; identifying a grinding region on the workpiece; and projecting a target grinding profile onto the grinding region on the workpiece. The method also includes: based a geometry of the workpiece and the target grinding profile, generating a tool path for removal of material from the grinding region to the target grinding profile; and assigning a target force to the target region. The method also includes, during a processing cycle: accessing a sequence of force values output by a force sensor coupled to a grinding head; navigating the grinding head across the grinding region according to the tool path; and, based on the sequence of force values, deviating the grinding head from the tool path to maintain forces of the grinding head on the grinding region proximal the target force.
