Artefacts

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 are of the highest priority

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 HGV gears

Masters

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)
