ABSTRACT:
The method for measuring dimensions of a workpiece (15) in a coordinate measuring machine having an optical probe (14) arranged to output radiation in a direction (21A) at an angle to a surface (15A) to be measured. The probe has a housing (17) which is arranged to lie clear of a projection formed by the surface (15A) to be measured and another, adjacent, surface (15B) so that the housing can pass clear of the projection and the measurement can be made without halting the machine at the surface to be measured.
The probe (14) is adapted for the radiation to be in the form of a cone (21) symmetric about an axis (Z1) transverse to the direction of movement of the probe so that the probe can sense all around the axis and therefore can sense any surface parallel or inclined to the axis regardless of the direction in which the surface faces.
