BOP Alignment
All critical interchangeable components are aligned to a highly complex coordinate system. Utilizing the laser tracker allows us to define an overall coordinate system with sub‐coordinate systems.
200 Drift Nest strategically placed over the complete stack to give us the capability to shoot into to the frame from any direction.

Cooling Tower II Sump Pump ‐ Turnaround
18 Sole Plates
Milling machinere‐positioned for each plate
Field machining 18 sole plates held to a tolerance that pushed the limit of field machining.
Each Sole Plate needed to be machined parallel to the world and to an elevation within 0.005” of each pad.
Utilizing the Laser Tracker: creating a world plane and a datum alignment coordinate system – controlling thermal expansion – we were able to achieve well within the tolerance.

Compressor Alignment
This project entailed inspecting the compressor while assembled on the shop floor.
The compressor was then dis‐assembled and installed in the plant.
Each component of the compressor was aligned utilizing the laser tracker and certified.

Turbine Alignment Dimensional Mapping Project
Drag‐Line Crane Excavator – One of the largest in the World
Dimensional Engineering was contracted to dimensionally control the line boring process for maintenance on the “Walking Mechanism” of an extremely large drag line.
With four 36” dia. bores that needed to be aligned over the distance of 20’ along with eight smaller bores. The line‐Bore had to be aligned precisely to bore each of the holes. With tight tolerances of +/‐ 0.002” the alignment was highly critical.
Line Boring Field Machining Alignment
Flange – Mapping – Root Cause AnalysisThis may sound familiar – for 10 years maintenance has been increasing the size of an O‐Ring that seals the filtration unit tight. During the last scheduled outage the decision was made to find the root cause of the repeating leak and the costly Power‐down and Power‐up. Dimensional Engineering was contracted to perform a dimensional study on the lower and upper flanges. The final report proved that there was not only warpage on the flanges ‐ shaped like a potato chip – the high spots of each flange were mating. This left a large valley in low spots – this was evident in the un‐even wear of the O‐Ring on the upper flange.

Laser Scanning ‐ Dimensional ValidationDimensional Engineering converted a hard template tunnel into a virtual scanning tunnel. Strategically placing repeatable mounting features even in the pit under the locomotive. All mounting features above ground and in the pit aligned in the samecoordinate system of each product line.
Laser Scanning ‐ Reverse EngineeringThis project entailed scanning the entire cabin area – from the forward bulkhead to aft. The scan data was then reversed engineered into a Solid Model – the data was used to retro‐fit a new interior that included bullet‐proof cladding, upgraded HVAC system, personnel seating .
Dimensional Study ‐ Reverse Engineering ‐ Virtual Build and Bolt ™
This project entailed laser scanning the entire unit. Reverse engineering the critical mounting areas. Compare data with replacement vessel to ensure vessel are correct.

Combining Tools
This project entailed laser scanning and reverse engineering the entire turbine. A laser tracker was used to create a coordinate system on each component.
Laser Mapping – Reverse Engineering ‐Major Turbine Rerate Project
Laser Mapping and InspectionInspection of the surface area on a wind turbine blade tool. We combined the Spherical Laser Scanner with the Laser Tracker to achieve the highest accuracy
Reverse Engineering ProjectThis project entailed the scanning and reverse engineering of a complete semi‐truck with high accuracy. The scan data was processed to a Tool Quality CAD model. The CAD model was then used to machine a wind tunnel fifth scale model and the base model for CFD analysis. The end goal of this project was to determine ways to increase the fuel mileage for the trucking industry.
Complexity:Large Scale ScanningHigh Quality Reverse Engineering
Reverse engineering projectThis project entailed scanning the truck cab. The data was used for dynamic crash analysis. The data acquisition was combined using a laser tracker and a portable arm scanner ‐ due to the large scale.
Virtual Build and Bolt™Validating all exposed flanges to ensure once unit is placed on‐site that all flanges mate to their respective flanges on location. The laser tracker and Focus 3D were combined on this project to ensure accuracy. The laser tracker set up the overall coordinatesystem and smaller internal flanges. The focus 3D was utilized to collect the entire structure for final documentation as well to validate larger flange openings.
Dimensional StudyIntercooler Validation using the Focus 3D combined with a laser tracker. The laser tracker defined the overall coordinate system and Focus 3D was utilized to collect the high detail areas.
