The present invention relates to a method and a tool for removing a partial region of a coating from a substrate, in which the partial region to be removed is removed by a machining process in such a way that an undercutting of the partial region of the coating that is to be removed takes place. For the undercutting of the partial region of the coating that is to be removed, at least one machining tool that is rotating relative to the substrate about an axis of rotation is moved relative to the substrate along a direction of advancement that runs parallel to a surface having the coating, wherein a layer of the substrate that is directly adjacent to the coating is also removed together with the coating. Considered in the direction of advancement, the tool thereby penetrates deeper into the substrate than into the coating to be removed.

The present invention has an object of providing a stepped wafer that can prevent a resist from remaining after development, and a method for manufacturing the stepped wafer. The stepped wafer according to the present invention is a stepped wafer having a step and whose main surface is thinner in a center portion and is thicker in an outer periphery. The step includes a curved surface with a radius of curvature ranging from 300 m to 1800 m.

Disclosed is an automatic wheel front burr removing device, including a station rotating motor, a station I manipulator, a station II manipulator, a station III manipulator, a station IV manipulator, a rim burr cutter head, a feeding slide plate I, guide posts I, cylinders I, a servo motor I, a feeding slide plate II, guide posts II, cylinders II, a servo motor II and a vision sensor. The station I is a wheel positioning and clamping station; the station II is a wheel rim burr removing station; the station III is a wheel cap section burr removing station; and the station IV is a wheel loosening and transferring station.

A jig and tool are provided for rotating the tool around a pipe or pipeline, for truing the pipe end. An operator can easily installation the jig into the pipe end, with or without the cutting tool installed thereto. The tool can be manually or motor driven for rotation about the jig and the pipe end. The attachment of the tool to the jig enables alignment of the tool's cutting face with the pipe end, with angular and axial adjustment available for obtaining a profile suitable for welding to like pipe ends. In an embodiment, the tool can track the pipe diameter to retain alignment despite out-of-round dimensional variation. The tool is operated and rotated about the pipe end to remove material and, as necessary, the tool is adjusted into the pipe end and the rotation about the pipe end is repeated for incremental removal of material therefrom.

A method measures an edge of a workpiece by scanning. The scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge facing tool of the edge-facing machine that faces the edge. The method can be performed by an edge-facing machine that includes at least one edge facing tool and that further includes a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.
