A workpiece processing device includes a workpiece supporting unit configured to support a workpiece so that the workpiece is rotatable around a first axis parallel to a central axis of the workpiece, a cutting unit having a blade configured to cut a surface of the workpiece, a detecting unit configured to calculate a position of a vertex of the surface in a direction along a second axis which is perpendicular to the first axis and parallel to the blade, and a control unit configured to control the workpiece supporting unit so that a cutting position on the surface is located at a vertex in the direction along the second axis, and relatively move the workpiece supporting unit and the cutting unit so that an incision direction of the blade is on a plane defined by the central axis and the cutting position, thereby forming a groove at the cutting position.

An apparatus, computer program product, and method provide for increased economy in maintaining working and backup rollers that are used to producing sheet metal of uniform thickness. Left and right necks of the roller are supported and rotated. A radial measurement is made of left and right necks to calculate a center of rotation of each neck. Radial positions of reference spheres centered at each end that define a gage reference line (GRL) are measured. Material is removed from the necks to not only increase roundness but also to move the center of rotation of each neck toward the GRL, enabling grinding/machining of a body portion of the roller to restore roundness with reduced waste of material.

A processing apparatus for brittle plate includes a table which holds a brittle plate, a processing head having a processing wheel for processing an outer peripheral edge of the brittle plate held by the table, a measuring portion which measures a positional shift amount Δ in an axis direction of the processing wheel with respect to the brittle plate, and a control portion which corrects a positional shift in a Z-axis direction of the processing wheel on the basis of a positional shift amount Δ in the axis direction of the processing wheel measured by the measuring portion and causes the processing wheel whose positional shift was corrected to process the outer peripheral edge of the brittle plate. The processing apparatus and its method can reduce time and labor of manually positioning of a processing wheel to the brittle plate after processing wheel replacement.

A polishing-pad laminated structure which allows for easy alignment of a through-hole of a polishing pad with a sensor head installed in a polishing table is disclosed. The polishing-pad laminated structure includes a polishing pad and a release sheet. The polishing pad has a through-hole located at a position corresponding to a position of a sensor head disposed in the polishing table. The release sheet covers an adhesive surface of the polishing pad. The release sheet is divided into at least a first release sheet and a second release sheet. The first release sheet has a surface area smaller than a surface area of the second release sheet.
