Artefacts are used to easily and quickly determine the uncertainties of gear
and spline measurements.
- Available for internal and external gear and spline geometries
- Different modifications in individual gaps possible
- Artefacts represent, in near ideal form, the geometrical characteristics of a gear profile
- Calibrations allow the traceability of characteristics to national artefacts
- Artefacts represent the highest instance
What are IC-Gear Artefacts?
- IC-Gear Artefacts have a similar profile to that of the workpiece to be tested
- They thereby meet the identity condition (IC) as defined in ISO 15530 (Technique for determining the measurement uncertainty of coordinate measuring machines
- The closer the artefact is to the measuring task, the more certain is the traceability of the measurement
- Geometrical size: Adaptable from small plastic gears to truck gears
Masters are used when calibrating instruments for size inspection.
- Available for internal and external spline instruments
- Geometry is identical to that of the specimen
- Setting masters mostly have a toothed section
- When using an electronic device, a setting master and a control master can be used in order to monitor the spread (recommended)
