Objective

Investigated the manufacturing bottleneck in a two-week combustion dampener welding process to identify the root cause of dimensional inconsistencies. The project focused on comparing as-manufactured combustion components against their CAD models to identify geometric deviations causing downstream welding operations.

Methodology

3D Laser Scanning: Captured the geometry of combustion components using 3D laser scanning to obtain detailed dimensional data from the as-manufactured parts
CAD Comparison: Imported scan data into Geomagic Control X and aligned the scanned geometry with the nominal CAD model to evaluate deviations from the intended design
Dimensional Deviation Analysis: Generated color deviation maps to visualize dimensional discrepancies, identify localized shape variations, and determine where the physical component diverged from its ideal geometry
Root-Cause Investigation: Analyzed the deviation patterns to understand how inconsistencies in the underlying body geometry contributed to fit-up challenges and potential delays during welding

Results

Identified dimensional inconsistencies in the bare-body component as a key contributor to the observed geometric variation
Provided scan-based evidence to designers to support root-cause investigation and corrective design decisions
Established a data-driven approach for evaluating manufactured component geometry against perfect CAD specifications
