Abstract: A manufacturing method forms components having a desired shape. A contoured surface is defined for a forming tool for forming a metal blank into the desired shape, wherein respective portions of the metal blank flow over the contoured surface during forming. An intrinsic material flow pattern resulting from the contoured surface is compared to a desired flow in order to identify regions of the contoured surface having an insufficient flow that creates areas in the formed metal blank receiving less than a desired amount of metal. A surface microtexture is applied onto the contoured surface in a pattern selected to increase metal flow along the identified regions by providing a friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.

Abstract: A cutting tool comprising first and second surfaces that intersect at an edge, wherein the first surface (e.g., a rake face, a flank surface or a margin) has a textured region comprising a multiplicity of recesses each having a length greater than its width. The recesses are distributed in a pattern comprising rows of recesses arranged lengthwise along respective lines with spaces between neighboring recesses. The recesses of one row are offset from the recesses of the next row. Each recess of the one row having one end portion that overlaps with an end portion of one recess in the next row and another end portion that overlaps with an end portion of another recess in the next row. The recesses are generally parallel to the edge.
Abstract translation: 一种切割工具，包括在边缘处相交的第一和第二表面，其中第一表面（例如，前刀面，侧面或边缘）具有纹理区域，该纹理区域包括多个凹槽，每个凹槽的长度大于其宽度。 这些凹槽以包括相应凹槽之间的间隔沿着相应的线纵向排列的凹槽排列的图案分布。 一排的凹槽与下一排的凹槽偏移。 一排的每个凹部具有与下一行中的一个凹部的端部重叠的一个端部和与下一行中的另一个凹部的端部重叠的另一个端部。 凹槽通常平行于边缘。
