1 System Inspection and Setup
- Check the condition of the stylus, probe arm and drive unit.
- Ensure stable mounting, correct levelling and proper system alignment.
- Verify the system settings, measurement range and applicable evaluation parameters.

Contour Machine Calibration
What Is Contour Machine Calibration?
Contour Machine calibration is the process of verifying and adjusting the accuracy of profile and contour measurements taken from a component's surface.
Contour machines are used to measure complex shapes, step heights, radii, angles and other geometric features by tracing the surface with a precision stylus.
Calibration helps ensure that the captured contour data accurately represents the component's actual geometry, supporting precise dimensional analysis, product quality and compliance with applicable ISO and JIS requirements.
Method of Contour Machine Calibration
The calibration process uses certified contour artefacts and reference standards to verify the machine's dimensional and profile-measurement performance.
2 Reference Artefact Verification
- Use certified contour standards such as step-height, radius and angle artefacts.
- Confirm that the reference artefacts have valid traceability to recognised measurement standards.
3 Linear Accuracy Check
- Verify the accuracy of horizontal X-axis and vertical Z-axis movement.
- Confirm precise displacement measurement throughout the applicable measuring range.
4 Profile Measurement Verification
- Measure known contour features such as radii, angles and step heights.
- Compare the measured results with the certified reference values.
5 Stylus Performance Check
- Verify stylus force, tip condition and tracing consistency.
- Ensure accurate surface tracking without excessive distortion or measurement interference.
6 Repeatability and Stability Test
- Perform multiple measurements on the same certified artefact.
- Evaluate the results to confirm measurement consistency, repeatability and system stability.
7 Error Adjustment and Compensation
- Apply suitable correction factors or recalibrate the system where adjustment is supported.
- Replace a worn or damaged stylus when necessary.
8 Certification and Reporting
- Provide a calibration certificate containing traceable measurement results.
- Record the measured values, certified reference values and applicable deviation analysis.
- Support compliance with relevant ISO, JIS and quality-system requirements.
