Dimensional Root-Cause Analysis
Use inspection results and process evidence to help isolate the source of dimensional variation instead of treating the measurement as the problem.
Metrology & Dimensional Analysis
Measure the Result.Understand the Cause.
Dimensional problems can originate from the machine, program, tooling, fixture, material or measurement process itself.
McMahon CNC Solutions uses inspection data as part of the broader manufacturing diagnosis to help determine where variation is actually entering the process.
Request Dimensional SupportMetrology Scope
Inspection Data ShouldHelp Diagnose the Process.
Measurement results become more useful when they are connected to how the part was programmed, held, machined and inspected.
CMM & PC-DMIS Support
Support informed by hands-on experience with Hexagon CMM equipment and PC-DMIS inspection workflows.
GD&T Interpretation
Review dimensional requirements and geometric tolerances in relation to the machining, setup and inspection process.
First-Article Support
Help evaluate first-article results and connect inspection findings back to machine, tooling, programming or workholding conditions.
Inspection Strategy
Consider whether the current measurement approach is capturing the process accurately and consistently.
Process-to-Measurement Correlation
Connect inspection data with the manufacturing process to determine whether variation originates in machining, setup, material or measurement.
Metrology Approach
Don't Correct an OffsetUntil You Know Why It Moved.
A measured deviation does not automatically identify the source of the problem.
Fixture movement, tool wear, machine behavior, programming, thermal effects, material condition and inspection strategy can all influence dimensional results.
The objective is to connect measurement evidence back to the manufacturing process before deciding what should change.
How Dimensional Analysis Works
Measure.Compare. Diagnose.
Review the Requirement
Start with the print, tolerance, inspection result and the specific dimensional concern.
Review the Process
Evaluate machine, program, tooling, workholding, material and inspection conditions that may influence the result.
Compare Evidence
Look for patterns in measurement data and process behavior instead of relying on a single inspection result.
Identify Corrective Action
Develop practical recommendations based on the actual source of variation rather than adjusting offsets without confirmation.
Inspection Experience
CMM, PC-DMISand Shop-Floor Metrology.
Experience includes Hexagon CMM equipment, PC-DMIS, GD&T, blueprint interpretation, first-article support and precision dimensional inspection.
Metrology support can be combined with CNC troubleshooting, programming, workholding or process optimization when dimensional problems cross multiple technical areas.
