Dimensional Analysis
Use inspection results and process evidence to understand patterns in dimensional variation before making corrective changes.
Metrology & Dimensional Analysis
Support for dimensional concerns, CMM results, GD&T interpretation, first-article review and inspection-related process questions.
Request Metrology SupportMetrology Scope
Inspection results are most useful when they are reviewed as a pattern rather than treated as a single pass-or-fail measurement.
Use inspection results and process evidence to understand patterns in dimensional variation before making corrective changes.
Support informed by hands-on experience with Hexagon CMM equipment and PC-DMIS inspection workflows.
Review geometric tolerances and dimensional requirements in relation to machining, setup and inspection.
Review first-article results and determine which dimensions or features require further process investigation.
Evaluate whether the current measurement method is appropriate, repeatable and capable of representing the part accurately.
Compare inspection results with machining conditions, setup and process history to identify meaningful patterns.
Metrology Approach
A measured deviation tells you what happened to the part, but not automatically why it happened.
Measurement repeatability, datum strategy, fixture condition, tool wear, machine behavior and material can all influence the result.
Reviewing the measurement in context helps avoid unnecessary offset changes or adjustments based on a result that has not been fully understood.
How Dimensional Review Works
Start with the tolerance, feature, inspection result and specific dimensional concern.
Compare available measurement results with relevant machining, setup and inspection conditions.
Determine whether the data suggests consistent drift, isolated variation, setup influence or another repeatable condition.
Use the available evidence to determine what should be checked or adjusted next.
Inspection Experience
Experience includes Hexagon CMM equipment, PC-DMIS, GD&T, blueprint interpretation, first-article support and precision dimensional inspection.
When the data points to a machining or setup issue, the findings can also help guide further programming, workholding or troubleshooting review.
Dimensional Concern?
Describe the tolerance, feature, measurement result and process concern. Do not submit proprietary drawings or confidential inspection files through the initial website request.
