ADVANCED OPTICAL INSPECTION

Clear measurements. Confident decisions.

Our dimensional inspection resources include a Mitutoyo coordinate measuring machine (CMM) and a KEYENCE IM-X1000 Series image dimension measurement system with its large-stage IM-X1540 configuration, alongside conventional metrology. Inspection methods are selected to suit component geometry and drawing requirements.

DIMENSIONAL VERIFICATION

The right inspection method for the right feature.

From complex geometric relationships to microscopic details, our quality and inspection capabilities support rigorous verification of manufactured components.

01 / 3D

Coordinate Measuring Machines (CMM)

Three-dimensional dimensional inspection for complex geometry, datums, feature locations and geometric dimensioning and tolerancing (GD&T).

  • Critical feature and positional verification
  • Profile, form and orientation evaluation
  • CAD / drawing-based dimensional comparison
02 / OPTICAL

Vision & Optical Measurement

Noncontact measurement and magnified inspection for small features, fine details, edge conditions and complex profiles.

  • Optical dimensional inspection
  • Small-feature and contour measurement
  • Visual examination of precision surfaces
03 / METROLOGY

Conventional Metrology

Purpose-selected precision instruments complement advanced measurement systems for efficient verification at every stage of production.

  • Micrometers, calipers and indicators
  • Pin, bore, thread and height gaging
  • Surface plates and comparison methods

COMPREHENSIVE METROLOGY

Inspection capabilities across the full spectrum.

A broad range of dimensional inspection and measurement methods supports precise verification from prototypes through production.

Coordinate & Optical Measurement

Coordinate measuring machines (CMM), KEYENCE IM-X1000 Series large-stage image measurement, optical comparators, toolmaker microscopes, and optical inspection.

Dimensional & Geometric Inspection

Digital height gauges, granite surface plates, dial and digital indicators, bore gauges, pin gauges, gauge blocks, and specialty fixtures for GD&T and dimensional checks.

Precision Hand Metrology

Outside, inside, and depth micrometers; digital and dial calipers; depth gauges; thread plug and ring gauges; radius, chamfer, and small-hole gauges.

Surface & Feature Evaluation

Surface finish and roughness evaluation, profile and contour measurement, visual inspection under magnification, and inspection of critical features.

Quality Planning & Records

Drawing and specification review, first-article and in-process inspection, final dimensional verification, inspection records, and calibration management.

Process-Focused Quality

ISO 9001-aligned quality practices, inspection planning, documented controls, corrective-action practices, and continuous improvement.

Inspection methods are selected based on part requirements. Specialized measurement methods and documentation can be discussed during project review.

A DISCIPLINED APPROACH

Quality doesn't begin at final inspection.

Successful inspection begins with understanding the drawing, the function of the part, and the features that matter most. Engineering, manufacturing and inspection work together to support a consistent result.

OUR ENGINEERING APPROACH →
01Requirements reviewReview drawings, specifications, tolerances and critical features.
02Inspection planningChoose appropriate measurement methods and checkpoints.
03In-process verificationMonitor critical features during manufacturing as appropriate.
04Final dimensional reviewConfirm conformance to agreed requirements and documentation needs.
QUALITY SYSTEM SUPPORT

Inspection, documentation & traceability.

The specific quality deliverables are defined with each project, allowing the inspection approach to align with customer requirements.

First Article Inspection

First-piece and first-article dimensional verification to establish confidence in the manufacturing process.

Dimensional Reports

Measurement records and inspection summaries structured around drawing requirements and agreed deliverables.

GD&T Interpretation

Measurement strategies informed by datum structures, form, orientation, position and profile controls.

Calibration & Traceability

Documented calibration controls and traceability considerations help support reliable measurement results.

Material & Process Records

Project-specific documentation, material identification and supporting records where required and agreed.

Continuous Improvement

Inspection findings can inform manufacturing adjustments, repeatability and process refinement.

Quality services and documentation are tailored to each project. Specific certifications, standards compliance, testing methods, or reports are not claimed unless separately confirmed.

THE TMI ADVANTAGE

Manufacturing expertise. Measurement confidence.
