Heavy rail / Urban light rail

Dimensional controls

Better understand fracture, wear and deformation phenomena for both new and used parts.

Objectives

  • Take dimensional measurements (radius, diameter, depth, angle, etc.):
    – For complex and three-dimensional parts (precision: ± 3 microns)
    – For new or used parts – measurement of dimensions specified on the plan (railway safety components, equipment, etc.)
  • Measure shape and position defects: Straightness, flatness, circularity, cylindricity, circular shape, parallelism, perpendicularity, coaxiality, concentricity, etc.
  • Measure surface condition, thread dimension, threads or grooves
