Updated Competence Database

The Competence database is based on the member's competence profiles in geometric and dimensional metrology. Each profile consists of several services which have been defined according to different dimensional metrology items (instruments, standards and artefacts, tools and methods, specific objects as well as supporting tasks).

The current database figures are:

  • 45 active members
  • 476 member records
  • 2776 services defined
  • 3045 available parameters
  • 1277 specified parameters

Single-flank working test

In the single-flank working test, two gears are meshed with each other at the prescribed centre distance so that either the right flanks or the left flanks remain in a continuous engagement (single-flank engagement). The single-flank working deviations of the right flanks of a gear generally are different from those of the left flanks of the same gear. Starting from a given position, the occurring deviations of the rotation angle, i.e. The angular position deviations of the gear compared with the theoretical ones (given by the positions of the mating gear and the teeth number ratio, are measured. This requires the use of a reference measuring system (reference gear unit) realising the zero-deviation angular positions (theoretical positions). The deviations are generally stated as a distance along the circumference of a test circle, e.g. The reference circle or the base circle. Alternatively, they may also be determined in an angular measure (e.g. Seconds or in milliradians or microradians).
