Abstract: A system includes: a pad removal assembly; a replacement pad reservoir; an inspection unit; and a controller. The pad removal assembly includes: a separating element arranged proximal a slot; and a guide surface opposite the separating element. The replacement pad reservoir: arranged adjacent the separating element and housing sanding pads configured to couple the sanding head; and including an aperture in alignment with the guide surface. The inspection unit includes an optical sensor defining a field of view directed toward an imaging plane. The controller configured to: access an image recorded by the optical sensor depicting an abrasive area of a sanding pad arranged on a sanding head; extract features from the image; interpret an abrasive degradation for the abrasive area in the image based on the features; and in response to the abrasive degradation exceeding a threshold degradation, triggering a tool change cycle.

Abstract: The present invention relates to a substrate processing method and a substrate processing apparatus for processing a substrate, such as a wafer. In the substrate processing method, rollers (11a, 11b) secured to eccentric shafts (13a, 13b) including a reference shaft (13a) and a movable shaft (13b) are brought into contact with the periphery of a substrate (W) having a notch (Nw), and further the rollers (11a, 11b) are moved in a circular motion, thereby rotating and circularly moving the substrate (W), and further, processing the substrate (W) by bringing a processing tool (201) into contact with the substrate (W). During processing of the substrate (W), a rotational speed of the substrate (W) is calculated based on measured values of a notch detection sensor (77) which is capable of detecting that the notch (Nw) has passed the movable shaft (13b), and an alarm is issued when the rotational speed of the substrate (W) is out of an allowable range which is set with respect to a theoretical rotational speed of the substrate (W).

Abstract: Methods and apparatus for shaping workpieces are described in which data representing the surface form of the workpiece is analysed to determine characteristics of curvature of the surface, and these characteristics are used to determine the size and form required for a tool to apply shaping treatment to all parts of the workpiece surface. Measurements of the actual workpiece are then compared with data relating to the required workpiece form, to determine the amount and distribution of material to be removed from the workpiece. A tool path for moving the tool over the workpiece to achieve the required shaping operation is then determined, and the tool and tool path data are provided to a shaping machine to carry out the shaping operation. The shaping tool may comprise an elastomeric body covered in a flexible cloth on which rigid pellets containing abrasive material are fixed. The specification discloses methods of manufacturing such tools, and also discloses methods for conditioning the pelleted cloth. There is also described a method of determining permissible amounts of tool offset to ensure smooth cutting of the workpiece.
