Measuring Transparent Geometry using Repliset

MEASURING GLASS USING STREURS REPLISET

The Streurs RepliSet produces replicas that are dimensionally correct and have an ultrafine detail reproduction. RepliSet can replicate details with dimensions less than 0.1 micron over the whole replica surface, which can be of any size or shape. RepliSet has no shrinkage and can thus be used for highly accurate metrological measurements.

For example, RepliSet was used to coat this lens for surface roughness inspection. The below shows data using Repliset and data from our Keyence VR6000 without ReliSet. The right (blue-to-green) data shows no lens contour and is not able to be measured because the white light fringe pattern passed through the material.

Measuring Piston Groove Surface Roughness

SURFACE FINISH OF PISTONS

Surface finish is a critical factor in the performance and longevity of engine pistons. As the primary component that converts combustion energy into mechanical motion, pistons operate under extreme conditions, including high temperatures, pressures, and friction. The surface finish of a piston directly influences its ability to retain oil for lubrication, form effective seals with the piston rings, minimize friction with the cylinder wall, and manage heat dissipation.

Surface finish of pistons is difficult to achieve due to their complex shapes, inaccessible geometries for tactile probes, varying material properties, and tight tolerances. Our non-contact optical profilometer (Keyence VR6000) allows us to three dimensionally capture these geometries and specify exactly where optimal measurements should be performed.

PIN BOSS GROOVE

Due to the short run available for measurement, tactile profilometers may struggle to perform this measurement. By angling the piston a few degrees we can capture 30-40 degrees of the groove. Below are some descriptions of the measurements:

  1. Ra & Rz values
  2. 3D map of surface with deviation values
  3. Multi-line profilometer measurements across the groove
  4. Surface profile and roughness profiles, sampling lengths

COMPRESSION RING GROOVES

These narrow but deep grooves make inspection particularly difficult, if not impossible for tactile probes. A distinct advantage of non-contact optical profilometry is the fast acquisition, repeatable measurements, and robust visualization of the geometry.

Optical 3D Profiling of Overmolded Filter

INSPECTING OVERMOLDED MESH FILTERS

Over-molded fine mesh filters are used in every industry for applications like oil, water, and air filtration. The Keyence VR Optical Profilometer allows us to inspect mesh protrusions to improve flow efficiency, reduce debris accumulation, and improving the lifespan of the filter.

We are able to produce high magnification, telecentric imaging of components for visual inspection, 2D programmable measurement routines, and submicron resolution 3D scans for CAD comparisons, reverse engineering, and FEA.
