A method of manufacturing a window may include cutting a window having a uniform thickness of about 20 m to about 100 m and polishing a cut surface of the window with a polishing pad having an elastic modulus less than an elastic modulus of the window while applying slurry to the cut surface of the window.

A method and system used for sanding objects such as auto body parts made of plastic. The method and system allow shop owners and technicians in the auto body industry to sand car bumpers with an abrasive paper having at least one sanding surface made of kraft paper prior to the priming process. The abrasive paper can be configured into corrugated fiberboard material. The abrasive paper will remove the rough or course areas left on car bumpers made of thermoplastic olefin (TPO) during the sanding process which will save auto body shops and technicians time and money spent on materials, specifically primer and sandpaper. The abrasive paper used to sand car bumpers can be made of virgin kraft and can be configured substantially in the shape of a disc, square or rectangle that will be affixed to a sanding device.

A processing apparatus includes an articulated robot having an arm distal-end portion to which a processing tool configured with a cutting edge portion and a profiling portion and a shape measurement unit are attached, and a processor. The processor, in a workpiece set state, recognizes, by measuring a shape of the workpiece using the shape measurement unit, a tilt of a profiled surface portion of the workpiece and a position of a process portion of the workpiece to generate processing-target-portion information based on the position of the process portion, generates processing-point information indicating a processing point, moves the arm distal-end portion to the processing point based on the processing-point information, controls an orientation of the processing tool in accordance with the tilt of the profiled surface portion of the workpiece to perform the specified processing on the workpiece using the processing tool.
