The present disclosure provides three-dimensional structures and related methods. The three-dimensional structures may define patterns of positive and negative spaces on opposing surfaces that combine to form the three-dimensional structures. The negative spaces of the patterns may intersect to form apertures through the three-dimensional structures, which may define linear or non-linear paths therethrough. The apertures may be configured to provide desirable characteristics with respect to light, sound, and fluid travel therethrough. Further, the three-dimensional structures may be configured to define desired stiffness, weight, and/or flexibility. The three-dimensional structures may be employed in embodiments including heat sinks, housings, speaker or vent covers, springs, etc.

Methods for forming a hole in a coated component are provided. The method may include forming a sacrificial layer over a ceramic barrier coating of a substrate, drilling a hole into the coated component such that any spatter formed during drilling deposits onto the sacrificial layer, and removing the sacrificial layer along with the spatter deposited thereon. The sacrificial layer may include a rare earth oxide (e.g., rare earth oxide particles). Intermediate ceramic matrix composite (CMC) component are also provided. The intermediate CMC may include a CMC body, an environmental barrier coating on the bond coating, and a sacrificial layer on the environmental barrier coating, with the sacrificial layer including particles of a rare earth oxide dispersed in a polymeric matrix.

The invention concerns a floating brake caliper for a vehicle disc brake, the brake caliper comprising a first portion that is arrangeable adjacent to a first side face of a brake disc of the vehicle disc brake and that is configured to receive a brake piston, a second portion that is arrangeable adjacent to a second side face of the brake disc wherein the second portion is configured to rest against a rear face of a brake pad of the vehicle disc brake, and wherein the second portion has a plate-shaped section that is configured to cover a geometric centre of the rear face of the brake pad and to cover at least half of the surface of the rear face of the brake pad and the invention also concerns a toll and method for surface machining of a brake caliper.

A hole is formed through the two or more parts, and a hollow tube is extended through the hole. A first plug is inserted into a first end of the tube, and a second end of the tube is pulled through the hole until the first plug is urged against the two or more parts. The second end of the tube is then cut so that the second end is flush with the two or more parts. A second plug is then inserted into the second end of the tub.

A connection element consists of a longitudinally oriented support structure that is at least partially hollow and a sensor unit that is arranged in the inside of the support structure, is connected to a signal transmission device, and is non-positively connected to the support structure. The required force for the non-positive connection is produced by internal stresses after a plastic deformation of the support structure during a joining process of the support structure and the sensor unit. A method for manufacturing a connection element consisting of a support structure that is at least partially hollow and a sensor unit includes positioning the sensor unit in a region of the support structure and, using radially movable tool segments, exerting a force on the support structure in the radial direction and at the same time reducing the periphery of the support structure in the region in which the sensor unit is positioned.

A method of assembling a detail to a flexible member includes positioning the detail against a plurality of reader pogos, and axially displacing the plurality of reader pogos to substantially conform to a detail contour. The method additionally includes recording reader pogo position data representing the detail contour, clamping a flexible member against a plurality of positioning pogos, and axially displacing the plurality of positioning pogos complementary to the reader pogo position data. In addition, the method includes deflecting, using the positioning pogos, the flexible member into a contour corresponding to the reader pogo position data, and assembling the detail to the flexible member.

In one embodiment of an enclosure device, a camera casing and light source casing are secured to a plate frame, and the enclosure device is configured to be mounted to an arm, such as a robotic welding arm. A shutter mounting arm may also be secured to the plate frame. A flap may be pivotally mounted to the distal end of the shutter mounting arm, such that the flap may be actuated between a first and second position by an actuator cooperatively engaged with the flap. The first position may be defined as to protect a camera lens positioned in the camera casing and a light source lens positioned in the light source casing. The second position may be defined as to not obscure a line-of-sight from either the light source and/or the camera to the work piece on the arm.
