Interference method for measuring thread elements

Conclusions

  1. 1.

    The interference method for measuring thread elements does not require any contact devices (knife-edges, cylinders, etc.).

  2. 2.

    The accuracy of fixing the edge of the component's contour by means of interference fringes is comparable with that of focusing the microscope to a scale graduation.

  3. 3.

    In checking threaded components by means of interference fringes it is possible to take into account random irregularities on the measured thread surface, which is difficult in measurements made by means of knife-edges.

  4. 4.

    A change-over to the interference method of measuring components does not require constructional changes in microscopes and can be carried out in any test laboratory. For this purpose it is sufficient to use the tables given above.
