摘要： A chemical mechanical polishing apparatus includes a platen to support a polishing pad, a carrier head to a surface of a substrate against the polishing pad, a motor to generate relative motion between the platen and the carrier head so as to polish an overlying layer on the substrate, an in-situ acoustic monitoring system, and a controller. In some implementations, the in-situ acoustic monitoring system includes an acoustic signal generator to emit acoustic signals and an acoustic signal sensor that receives acoustic signals reflected from the surface of the substrate. The controller is configured to detect exposure of an underlying layer due to the polishing of the substrate based on measurements from the in-situ acoustic monitoring system.

摘要： A grinding setting selection system for a robotic grinding system is presented. The system includes an abrasive rotational speed retriever that retrieves a current rotational speed of a grinder in the robotic grinding system. The system also includes an end effector load retriever that receives a current end effector load of an end effector in the robotic grinding system. The system also includes a material removal predictor that, based on the retrieved rotational speed and the end effector road, predicts a material removal rate. The system also includes a setting adjuster that, based on the predicted removal rate, provides a setting adjustment for the robotic grinding system. The setting adjustment alters a mechanical setting of the robotic grinding system. The system also includes a setting communicator that communicates the setting adjustment to the robotic grinding system.

摘要： A method of grinding or turning a workpiece, such as a bearing workpiece, involves several steps. One step includes locating the bearing workpiece on a chuck with an axis of rotation of the chuck positioned off-center relative to an axis of the bearing workpiece. Another step includes determining an offset between the chuck's axis of rotation and the bearing workpiece's axis based on the off-center position between the chuck's axis of rotation and the bearing workpiece's axis. Yet another step includes determining a path of engagement of a grinding wheel relative to the bearing workpiece based on the offset previously determined between the chuck's axis of rotation and the bearing workpiece's axis.
