Patent attributes
A disclosed apparatus and related method are directed to engagement of a tool with a workpiece, utilizing a first platen having a first axis of rotation and a workpiece mount and a second platen having a second axis of rotation and a tool mount. The first platen moves the workpiece mount along a first arc by rotating about the first axis of rotation, and the second platen moves the tool mount along a second arc by rotating about the second axis of rotation. The first and second platens rotate relative to one another such that a tool-workpiece intersection point (e.g., a tool endpoint), which is offset from and fixed relative to the second platen, follows a tool path that is offset from and fixed relative to the first platen as the first and second platens rotate.
