An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

A method and rivet apparatus to rivet a workpiece comprises an upper riveting portion and a lower riveting portion. The lower riveting portion comprising a fixed base, support member, and a pin assembly. The pin assembly comprises a center pin, a forming pin, a first biasing member, an outer shroud, and a second biasing member. The center pin pushes against a tail of a rivet to deform the tail of the rivet. The forming pin, fixedly coupled to the support member, pushes against the tail of the rivet to deform the tail of the rivet. The first biasing member, disposed below the center pin, biases the center pin through the forming pin and away from the support member. The outer shroud encircles the forming pin and the center pin. The second biasing member, disposed below the outer shroud, biases the outer shroud away from the support member.

A machining center for machining a center groove on a pulley and a flange formed at opposite ends of a crankshaft of a vehicle includes a measurement unit configured to measure a moment of the crankshaft when the crankshaft is loaded and actuated, a control unit configured to calculate an imbalance amount of the crankshaft and to derive center drill coordinates for removing the imbalance amount, a compensation unit mounted in a base frame and configured to compensate a position of the crankshaft by rotating first and second rotating elements based on the center drill coordinates inputted from the control unit when the crankshaft is transported and clamped by a clamping system, and a machining unit configured to machine the center groove in the pulley and the flange of the crankshaft.

A holding apparatus/workpiece adapter apparatus arrangement includes a holding apparatus and a workpiece adapter apparatus. The workpiece adapter apparatus is positioned and fixed, with a workpiece fastened thereto, by the holding apparatus. The holding apparatus has partially cylindrical positioning elements, which engage in an associated cylindrical positioning recess and a positioning slot and position the workpiece adapter apparatus in an x and a y direction. The workpiece adapter apparatus bears by mating contact surfaces against contact surfaces of the holding apparatus and is clamped by linearly displaceable clamping elements and pressed against the contact surfaces, and thus positioned in a z direction. For clamping, clamping surfaces of the clamping elements bear against mating clamping surfaces of the workpiece adapter apparatus.

A manufacturing cell comprises a machine tool that has a tool carrier carrying a tool unit and has two adjacent workpiece paths oriented in a longitudinal direction. The tool unit can be displaced relative to a machine bed of the machine tool in a transverse direction and in a vertical direction. At least one workpiece carriage per workpiece path can be displaced in the longitudinal direction along the machine tool. The tool unit can be displaced in the longitudinal direction relative to the machine bed and/or relative to the workpiece carriages. The tool carrier overhangs or projects beyond the workpiece paths. The individual workpiece carriage can also be displaced in the longitudinal direction along the workpiece supply. Furthermore, the workpiece supply has at least one lowerable or tiltable stop device per workpiece path.

A control device of a machine including: an operating condition analyzing unit that analyzes an operating condition of the program, and performs a notification when the tool to be exchanged is not adjusted; an operating condition storage unit that stores the operating condition of the program at a time of exchanging the tool; a state restoration confirming unit that confirms whether an internal state of the machine and/or the control device is restorable so that an operation of a predetermined block of the program is performed again after the operation and a stop of the predetermined block after exchanging the tool; and a state restoration executing unit that, in a case in which the internal state is confirmed to be restorable, restores the internal state to a state at the time of exchanging the tool based on the stored operating condition of the program at the time of exchanging the tool.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.
