Adaptive processes for improving integrity of surfaces

An enclosure for an electronic device, the enclosure comprising:

• a first housing part including a metal substrate having an external surface, and (i) an opening machined into the external surface, and (ii) walls that extend from the opening and terminate at a bottom surface, wherein the bottom surface is offset from parallel to the external surface by an amount that exceeds a tolerance value
• a layer of adhesive material that is disposed over the bottom surface so as to define a modified bottom surface, the modified bottom surface being parallel to the external surface, wherein the layer of adhesive material has a geometry in accordance with a bottom surface profile of the bottom surface and an external surface profile of the external surface;
• and
• a second housing part having an internal surface and an exterior surface opposite of the internal surface, wherein the internal surface overlays the modified bottom surface such that the exterior surface of the second housing part is co-planar to the external surface of the first housing part.

A non-transitory computer readable storage medium storing instructions that, when executed by a processor of a computing device, cause the computing device to execute steps for assembling a housing for an electronic device from a first housing part and a second housing part, the first housing part including a metal substrate having an exterior surface, the exterior surface having (i) an opening machined into the metal substrate, and (ii) walls that extend from the opening and terminate a bottom surface, wherein the steps include:

• forming a machined housing part by machining the first housing part, the machined housing part having a bottom surface that is offset from parallel to the exterior surface by an amount that exceeds a tolerance value;
• depositing a layer of adhesive material, in a controlled manner, onto the bottom surface, wherein a geometry of the deposited layer of adhesive material is in accordance with a bottom surface profile of the bottom surface and an exterior surface profile of the exterior surface such that an external surface of the deposited layer of adhesive material is parallel to the exterior surface;
• and
• placing a first surface of a second housing part through the opening and onto the external surface of the deposited layer of adhesive material such that a second surface of the second housing part, opposite the first surface, is co-planar with the exterior surface of the machined housing part.
