A forming tool stamps sheet metal blanks into a desired shape. A contoured surface is defined for the forming tool so that 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 coefficient of friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.

Forming tools having textured surfaces

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.

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.

Cutting tools with textured surfaces

A method and apparatus for calibrating a tool. A moveable blade connected to the tool may be deflected towards an inward position with respect to the tool. A force applied to the moveable blade may be detected by a biasing mechanism in the tool using a sensor when the moveable blade is in the inward position with respect to the tool. The biasing mechanism in the tool may be adjusted if the force is not a desired force.

Calibration system for a deburring tool

A vacuum-mounted clamp for clamping a first component to a second component. The clamp includes a substantially rigid body having an application face, a back face opposite the application face, a side, and a vacuum port extending between the application face and the back face. The application face has a step adjacent the side for engaging the first component. The clamp includes a flexible seal connected to the rigid body adjacent the application face. The seal has a vacuum port in fluid communication with the vacuum port in the primary body and a periphery for contacting the second component to create a vacuum area between the clamp and the second component. The vacuum port of the body and the seal are in fluid communication with a vacuum generator for generating a vacuum in the vacuum area.
