A method of manufacturing a part using a cutting machine includes placing a non-porous sheet on a surface of a material cutting machine, removing material from the non-porous sheet to form a plurality of sections of the part, and while the non-porous sheet is present on the material cutting machine, forming fastening holes within the sections. The method further includes removing the sections from a remainder of the sheet, placing the sections together such that each section of the part abuts another section, and inserting fasteners through the fastening holes of the sections.

In order to produce a clutch pack (3), clutch plates are cut from an electrical steel strip or sheet, arranged on top of one another to form the clutch pack (3) and connected to one another within the clutch pack (3). The material of the clutch plates is locally plasticised in the edge region via the generation of frictional heat by means of at least one tool (9), in such a way that the material of at least adjacent clutch plates is mixed with the tool (9) such that, after the plasticised material has cooled, these clutch plates are integrally connected to one another. The device used for this purpose has at least one punch press and/or at least one receiving means for one or more clutch packs (3). In addition, the device has at least one welding tool that is rotatably driven about its axis and can be moved in a transverse direction to its rotational axis.

A wave plug of a wave generator of a wave gear device includes: a metallic outer hollow body with an elliptical wave plug outer circumferential surface formed thereon; a metallic inner hollow body with a wave plug inner circumferential surface formed thereon; and an intermediate hollow body sandwiched between the outer hollow body and the inner hollow body. The intermediate hollow body includes CFRP layers. It is possible to implement a light wave plug in which a big hollow portion can be formed while assuring a required rigidity. Using the wave plug makes it possible to implement a light wave gear device which allows jumping to occur at a high load torque and which includes a big hollow portion.

A race for a mechanical clutch assembly may be formed from multiple race layers that assembled from pluralities of stamped arcuate segments. First and second race layers may have the same shape when their arcuate segments are assembled are assembled. The arcuate segments of the first race layer may be identical to each other, and the arcuate segments of the second race layer may be identical to each other, but the first layer arcuate segments are not identical to the second layer arcuate segments. Interlocking joints between the first layer arcuate segments are not aligned with interlocking joints between the second layer arcuate segments when the race layers are joined together and aligned for use in the mechanical clutch assembly.

A method for additive manufacturing of a three-dimensional object includes: a) identifying a set of sequentially extending planar cross-sectional shapes of the three-dimensional object; b) cutting a metal sheet into a plurality of planar metal pieces, each metal piece cut to a metal piece shape corresponding to a respective one of the cross-sectional shapes, wherein the metal sheet has a first face with a first plurality of barbs extending therefrom, and an opposed second face with a second plurality of barbs extending therefrom; c) cutting a substrate sheet into a plurality of planar substrate pieces, each substrate sheet cut to a substrate piece shape corresponding to a respective one of the cross-sectional shapes; and d) positioning the metal pieces and the substrate pieces in facing relation in an alternating pattern and in sequential order, and pressing the metal pieces and substrate pieces together to force the barbs to penetrate the substrate pieces.

An additive manufacturing system, method of manufacturing, and fabricated part. The system uses a material joining laser system to join together foil sheets to form a metal part. The material joining laser system can be configured to join adjacent foil sheets together in a substantially uniform manner. The manufacturing system also includes a material removal system that removes material from selected locations of the foil sheets to shape the foil sheets to correspond with selective slices of the part. The material removal system can be a laser system, such as a laser system configured to remove material from a foil sheet without removing material from an underlying layer. One embodiment involves the manufacture of amorphous alloy components.

The present invention discloses a method and a system for additive manufacturing of a complex metal part by sheet lamination, and belongs to the field of manufacturing. A three-dimensional data model of a part is sliced into metal sheets, the metal sheets are molded, and each metal sheet is combined into the part by using diffusion welding or friction welding. A diffusion welding or friction welding technique is introduced in additive manufacturing, so that a production capacity of additive manufacturing is further expanded and supplemented, so as to manufacture parts with higher precision and better finish quality.

Disclosed herein is a method. The method includes identifying a first location on a first part to place a first shim tab to form a first portion of a compound shim. The method also includes applying the first shim tab to the first location on the first part with an end-effector. The method also includes identifying a second location directly adjacent to the first location on the first part to place a second shim tab. The method also includes applying the second shim tab to the second location on the first part with the end-effector to form a second portion of the compound shim. The method also includes applying a third shim tab to the second shim tab at the second location to increase a thickness of the second portion of the compound shim.

A method of additive manufacturing of a component includes cutting a plurality of sheets, each sheet corresponding to a respective cross-section of the component, tack welding the sheets to one another to form a stack, arranging the stack in a mold, and spark plasma sintering the tack-welded stack of sheets to reduce vacancies and dislocations between adjacent sheets of the stack.

A method includes providing a ceramic matrix composite (CMC) seal arc segment that has radially inner and outer sides, attaching an abradable layer on the radially outer side of the CMC seal arc segment, providing a carrier to support the CMC seal arc segment, the carrier including a ridge, and sliding the CMC seal arc segment relative to the carrier such that during the sliding the ridge cuts a groove into the abradable layer, the ridge remaining disposed in the groove to thereby provide a labyrinth seal that partitions the cooling cavity between the carrier and the CMC seal arc segment into sub-cavities.
