Dimensional Inspection

Overview: Our Dimensional Inspection services ensure that your components meet precise specifications and quality standards. Using advanced metrology equipment, we provide accurate measurements and detailed reports for a wide range of parts.

  • Coordinate Measuring Machine (CMM) Inspection

    High-precision inspections using advanced CMM technology to verify the dimensions of your components. Suitable for complex geometries and high-tolerance parts.

  • Vision System Inspection

    Automated 2D and 3D inspections using cutting-edge vision systems. Ideal for detailed measurements of intricate parts and assemblies.

  • Portable CMM Inspection

    Onsite inspection services using portable CMM equipment, allowing for flexible and accurate measurements of large or difficult-to-move components.

Actual Comparison / Part To Part Comparison

  • Color maps are an excellent way to visually identify sink, warp, twist and other undesirable characteristics as you evaluate your parts.
  • This is especially useful for organic and complex shapes where traditional CMM inspection may lack coverage and point density.
  • For product and process development, deviation analysis using 3D scanning is very cost - effective, you can quickly check the profile of your part against nominal CAD or a golden part

Process Of Dimensional Inspection

  • Determine the inspection requirements, including which dimensions need to be measured and the acceptable tolerances.
  • Preparation: Calibrate inspection equipment, ensure proper lighting conditions, and set up the part for measurement.
  • Measurement: Use the chosen inspection method to measure the dimensions and geometries of the part accurately.
  • Analysis: Compare the measured data against the design specifications or CAD models to identify any deviations or out-of-tolerance conditions.
  • Reporting: Document the inspection results in a detailed report, including any deviations found, measurement data, and recommendations for corrective actions.
