Abstract
Official abstract text for this publication.
The described embodiment relates generally to the development of a finishing process for a device housing. The device housing can be formed of a thermoplastic, or a metal such as aluminum or stainless steel. A method and an apparatus are described for accurately measuring the amount of material removed during a finishing process. More particularly embodiments described within this application disclose a method of accurately measuring material removal during a finishing process across a curved or spline shaped surface by drilling an array of pockets along a surface of the device housing, where the drilled pockets can be used to measure material removal rates with a high degree of accuracy.
First claim
Opening claim text (preview).
What is claimed is: 1. A machining process calibration system for a workpiece, comprising: a robotic arm having at least five degrees of freedom and configured to follow a tool control path that maintains the robotic arm in an orientation substantially normal to a surface of the workpiece; a pocket forming tool mechanically coupled to the robotic arm during a pocket forming operation in which a plurality of pockets are formed in the workpiece at an angle substantially normal to…
