The UK National Gear Metrology Laboratory (NGML) is exceptionally well equipped to measure gears and related products including:
- Spur and helical involute gears.
- Straight and spiral bevel gears.
- Involute and non-involute worms.
- Worm wheels.
- Shaping cutters.
- Shaving cutters.
- Involute splines.
- Straight sided serrations.
- Free form scanned surfaces (such as tooth root radius) and conversion to a CAD format.
- General co-ordinate measurement by scanning or point measurement.
- Surface roughness.
The equipment within the laboratory includes:
- An enhanced Klingelnberg P65 Gear Measuring Centre used as the reference calibration and measurement machine (installed 2003).
- Höfler EMZ 632 CNC gear measuring machine (installed 1994).
- Zeiss WMM 850 CMM updated by IMS Ltd (updated 2009).
- Talyor Hobson Form Talysurf 50E surface roughness and form measuring instrument.
- Klingelnberg PEW 02 Transmission Error measuring machine.
To maintain the accuracy of these measuring instruments the temperature within the laboratory is controlled to within 20.0°C ± 0.3°C.
