We were discovering the new case for aircraft parts manufacturing for the past two months. Quality assurance is one of the most important stages in the process. The thickness inspection of a wing panel which could be five meters long and two meters wide needs to be performed in about a thousand spots. One of the commonly used approaches is to mark these spots by the mylar, a plastic stencil covering the panel. It has a number of problems though:
- Preparing the mylar
- Placing it in the correct position
- Progressing through each end every spot without missing any
- No control over the range of spots out of range
A Mixed Reality solution overlays a virtual layer over the wing surface with the spots to be measured. The marker is used for recognition:
However, in the first trials the grig was unstable while the procedure required high accuracy. We have found a way to stabilize it ultimately:
To assist in performing the inspection further we added an indication of the active point and the output of measurements:
Whether the measurement fits the tolerance range is indicated by color.
This prototype was successfully tested and will be used as a base for a pilot product.
