conditions / procedure
Coordinate measuring
machines with a calibrated measuring volume of:
X = 800 mm
Y = 1040 mm
Z = 400 mm
(the designation X, Y, Z
name the axes of the
coordinate system in
notation of the
manufacturer)
Tactile measurement in the
form of single-points measurements using a calibrated
coordinate measuring machine and determination of
geometric parameters defined through control geometries (single points,
straight lines, planes, circles, balls, cylinders, tapers,
toroids) using the evaluation software of the coordinate measuring machine.
Single-point measuring can
be carried out either with
fixed, predefined measuring
force or with extrapolation
on measuring force zero.
Single-point measurements
in the form of „Self-centring
measurements” are not
used within the framework
of the accreditation.
Calibrations are carried out
with probing elements with
diameters of between
1 mm to 30 mm.
