METHOD OF MODIFYING A DATUM SURFACE FOR IMPROVED PART OFFSET CONTROL

摘要

Devices and techniques for improving the fit between multiple components of a part are described. In particular embodiments, the techniques involve providing features that allow for offset adjustments of components during an assembly process after the components have been already been machined to final dimension. The features can protrude from a mating or datum surface of one or both of the components. The heights of the features can be modified so as to modify a dimension of the mating surface, providing minor offset control for critical dimensions during an assembly process. In some cases, the features are provided on a separate insert piece that can be easily modified and replaced if necessary.

1. A method of adjusting an offset related to a first component and a second component, the first component configured to couple with the second component, the method comprising:
pre-assembling the first component with the second component, wherein the first component includes a mating surface having a protruding feature; measuring an offset value related to the first component and the second component; and modifying the mating surface by reducing a height of the protruding feature so as to reduce the offset value to a final offset value.
