Method for process control of burnishing

摘要

An apparatus for process control of a burnishing process including a body having a first end (14) and a second end (16), at least one process control coupon (100), and structure for attaching the process control coupon (100) to the body. At least one edge (101, 102, 103, 104) of the process control coupon (100) is clamped along the entire length thereof during burnishing. A method of process control for burnishing of components comprising selecting at least one process control coupon (100), selecting an apparatus (10) for holding the process control coupon(s) (100), attaching the process control coupon(s) (100) to the apparatus (10), selecting a region (301) on the surface (121, 122) of the process control coupon(s) (100) for burnishing, burnishing a patch (303) on the selected region (301) using a burnishing process, and, measuring at least one physical parameter at a selected location of the process control coupon(s) (100) after burnishing.
