Customer's Challenge

The compressor foundation need to be machined down to enable installation of compensators. In order to determine the machined heights of each pads, the centerline of the auxiliary engine need to be established accurately which conventional geometric alignment instrument may not be able to achieve easily. Furthermore, the restrictive space in engine room make the range of suitable machining equipment very limited.


Our 3D measurement instrument, API laser tracker was deployed for this assignment for its portability and ability to run using batteries. By collecting the measurement data via SpatialAnalyzer software, the best fit centerline and horizontal plane of the auxiliary engine are established to measure the distances between individual pads and horizontal center plane. With this, the amount of material removal on each pads to accommodate the compensators are identified.


As the API laser tracker is a precision 3D measurement instrument, it is able to extract much more dimension data accurately which enable extracting of multiple information for clear overview on machineries’ present status and allow client to work out the best strategies to tackle their engineering problems in the shortest time.
Coupled with our customizable in situ equipment, we are able to provide options to our client depending on the lead time and precision required. With a total of 4 surveys, milling of the 4 seating faces, drilling, tapping and spot facing, the whole tasking was completed within 46hrs .
