According to one example, there is provided a non-transitory computer-readable medium on which is stored computer-readable instructions that when executed by the computer cause the computer to obtain data relating to a set of objects generated by an object generation system, display using the obtained data a visualization of the set of objects, receive user input identifying a set of objects displayed in the visualization, supply, based on set of identified objects, obtained data, or data derived therefrom, to a post-processing module that is to process a set of objects corresponding to the set of identified objects.

A method forms a crowning on a sintered component made from a sintering powder, in particular on the teeth of a sintered component including a toothing. The sintered component is calibrated in that the sintered component is introduced into a calibration tool. The sintered component includes a forming chamber with at least one forming wall. In the forming wall a crowning is formed which is inverse to the crowning of the sintered component to be formed. After calibration the sintered component is removed again from the calibration tool. The size of the forming chamber of the calibration tool remains unchanged at least for the time period beginning with the insertion of the sintered component into the calibration tool and ending after the removal of the sintered molding from the calibration tool.

A high-strength magnesium alloy member is suitable for products in which at least one of bending stress and twisting stress primarily acts. The member has required elongation and 0.2% proof stress, whereby strength and formability are superior, and has higher strength and large compressive residual stress in the vicinity of the surface of a wire rod. In the magnesium alloy member formed as a wire rod in which at least one of bending stress and twisting stress primarily acts, the wire rod includes a surface portion having the highest hardness of 170 HV or more in the vicinity of the surface and an inner portion having a 0.2% proof stress of 550 MPa or more and an elongation of 5% or more, and the wire rod has the highest compressive residue stress in the vicinity of the surface of 50 MPa or more.

A method of forming a component from a powder metal includes forming the component to a desired shape from the powder metal, heating the component to a burnishing temperature of 900 to 1300 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface.

A method of forming a component includes heating the component to a burnishing temperature above 500 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface. The burnishing process at an elevated temperature may be integrated into other processes, such as the sintering or heat treating processes.

A sliding member (1) is formed of a sintered compact. The sintered compact includes: a base layer (3), which mainly contains an Fe-based structure and further contains 1.0 wt % to 5.0 wt % of Cu, a metal having a melting point lower than a melting point of Cu, and C; and a sliding layer (2), which is sintered together with the base layer (3) in a state of being held in contact with the base layer (3) and has a sliding surface (A). The sliding layer (2) mainly contains an Fe-based structure containing at least one kind of alloy element selected from Ni, Mo, Mn, and Cr and further contains Cu and C, and the content of Cu in the sliding layer (2) is larger than the content of Cu in the base layer.

A method of sizing a cavity in a part and a part made from such method. The method includes forming the part having the cavity, including forming a plurality of protrusions extending within the cavity from at least one internal surface of the cavity, the protrusions having distal ends bordering an unobstructed portion of the cavity, the unobstructed portion having an initial dimension at least partially defined by a position of the distal ends, pressing a deforming element against the distal ends of the protrusions to plastically deform the protrusions toward the at least one internal surface of the cavity and increase the initial dimension to a final dimension, and disengaging the deforming element from the distal ends.

According to a method for the surface compaction and calibration of a sintered component, the sintered component runs along an axis through a plurality of die sections of a die, the inner diameter of which decreases in pressing direction and wherein the individual die sections are arranged such that a following die section of the plurality of die sections directly adjoins the corresponding die section which precedes it in pressing direction, and after the surface compaction at the last die section with decreasing inner diameter there is a relaxation of the sintered component in a relief section directly adjoining the last die section, which relief section has a greater diameter than the immediately preceding last die section of the die section with a decreasing inner diameter. The sintered component is calibrated in the relief section, whereby the inner contour of the relief section corresponds with the intended contour with the nominal dimensions of the sintered component.

The invention relates to a method for calibrating, in particular, sintered pressed parts, wherein a calibration procedure of each individual pressed part is controlled depending on at least one specific pressed part parameter of the respective pressed part measured before calibration and/or depending on at least one production parameter of a preceding pressing and/or sintering step of the respective pressed part.
