What we measure
Bolton Works performs inspection using a combination of CMM, structured light scanning, and industrial CT when internal geometry or material access requires it. Programs typically include:
First article inspection (FAI)
Document as-built condition against drawing and CAD requirements for release and customer submission.
Deviation mapping
Compare millions of scan points to CAD or a scanned reference to visualize out-of-tolerance zones instantly.
Assembly fit analysis
Understand how mating parts interact before expensive rework or tooling changes.
Wear analysis
Quantify material loss and change over time for maintenance and life prediction.
Coating thickness analysis
Assess coatings and surface build-up with dense surface data.
Shrink & process insight
Support molding and manufacturing process feedback with full-field geometry.
Deviation mapping in depth
One of the most powerful uses of 3D scanning is deviation mapping. Scan data is compared to
your CAD model or a scanned reference part. Beyond pass/fail, color maps give immediate visual
insight into problem areas for dimensional checks, wear, coating thickness, and shrink.
Because dense data is not locked to a single datum scheme up front, teams can evaluate
“what-if” alignments. The same dataset supports later GD&T extraction without reacquiring
the part — valuable when questions evolve after the first design review.
Contact + non-contact, deliberately combined
Structured light scanning captures complex freeform shape efficiently. High-accuracy CMM measurement remains the right tool for tight-tolerance critical features. For parts with demanding requirements, correlating key features with CMM is part of our standard operating practice.
