... in simulation and therefore can be optimized prior to product launch. However, a bigger blank may be needed to accommodate draw beads, and properly engaging the beads may require a more complex die and die process. A blanking die or laser-cut blanks may be needed if nonrectangular blanks are used. Similar...

.... Both the thread roots and the outside surface finishes were examined. ARL contacted Lasertec USA Inc. for scanning confocal laser (SCL) analysis (with the use of a 1LM21W laser scanning microscope) of the thread roots of the rods. SCL analysis is a sophisticated technique utilized to determine...

Surface-modified layers have a greater similarity to metallurgical alloying rather than the chemically adhered and mechanical bonds created by conversion or organic coating methods. Ion implantation and laser surface processing are two methods of surface modification. Ion...
