A method of processing a workpiece includes holding a face side of the workpiece on a holding table having a region made of a transparent material and forming a processed groove in the workpiece with a cutting blade. The forming a processed groove includes capturing an image of the processed groove on a reverse side and the face side of the workpiece, and detecting whether a position of a first central line of the processed groove on the reverse side and a position of a second central line of the processed groove on the face side are in conformity in a predetermined plane. If the positions of the first and second central lines are not in conformity, then the forming a processed groove further has correcting a position of the center of the cutting blade in order to bring the positions of the first and second central lines into conformity.

A curved face grooving blade having a curved grooving portion and a clamping portion connected thereto. The grooving portion having an insert seat defining upward and downward directions. The clamping portion has a bottom wedge surface located in an inward and downward direction relative to the remainder of the clamping portion.

A spacer, blade core, assembly and methods for blade and blade core assemblies, including gang blade heads, include openings in blade cores for receiving spacers. A spacer and its opening can be the same shape or different shapes, and spacers can be interconnected or disconnected from each other. A spacer can be in contact or engaged with two blades, three blades, or more.

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.

Methodology for reclaiming metal from insulated and/or shielded and/or jacketed power cables present on supporting conveyor belts, by waterjetting using stationary and/or spinning nozzles.

An adjustable trimming mechanism includes a wheel module having a wheel mount and a wheel disposed on the wheel mount, and a motor module having a motor mount, a slide rail disposed on a side of the motor mount, a motor, a slider disposed on the slide rail and connected with the motor, a pull rod and a positioning member threadedly disposed on the slide rail. One of the motor and wheel mounts is located above the other. An end of the slider is connected with the pull rod so that the slider drives the motor to displace together frontward or backward when being pulled by the pull rod. Therefore, when the positioning member is loosened, the position of the motor is adjustable frontward or backward by the cooperation of the pull rod and the slider and thereby the cutter installed on the motor is adjusted simultaneously.

A cutting apparatus includes a processing feed direction determining mechanism. The processing feed direction determining mechanism includes an imaging unit that images a region including a cut groove and a recording unit that records chipping data of the imaged cut groove. The recording unit records first chipping data of a cut groove formed by cutting a workpiece from a first direction, second chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the first direction, third chipping data of a cut groove formed by cutting the workpiece from a second direction orthogonal to the first direction, and fourth chipping data of a cut groove formed by cutting the workpiece from a direction opposite from the second direction.

Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.
