Testing the Mechanical Characteristics and Contacting Behaviour of Novel Manufactured and Assembled Sphere-Tipped Styli for Micro-CMM Probes

Abstract

International audienceThe effectiveness and versatility of the probes used on micro-co-ordinate measuring machines is currently limited by the dimensions, geometry and quality of the spherical stylus tips available. A shaft fabrication and gluing process is demonstrated to assemble a sphere-tipped stylus for tactile micro-co-ordinate measuring machine probes. The contact behaviour of the manufactured micro-styli is investigated both in a static and a vibrating mode. The ultimate strength of the glue joint is also investigated. It is concluded that the assembly of styli using the presented method is viable, however, that stylus shafts below 40 μm diameter may require new manufacturing methods

High-precision horizontally directed force measurements for high dead loads based on a differential electromagnetic force compensation system

“…In the literature, a number of techniques and state-of-theart sensors have been applied in precision force measurements, down to pN resolution/precision [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The common principle employed in most of these studies is the deflection measurement of the dead load, either by a torsional or pendulum-based balance.…”
