Typologie et conception des machines à mesurer tridimensionnelles : un état de l’art

Abstract

Abstract. This article is limited to coordinate measuring machines CNC ordered without addressing probing systems, measuring arms or optical techniques. We present an inventory of major architectures based on the standard ISO10360-1. Then, the key points of the design of coordinate measuring machines are studied. These key points are related to the design of the slideways, the Abbe principle introduced by Ernst Abbe in the late nineteenth which remains a fundamental point, the position of drives and materials. The geometry correction software becomes essential in the mid-1980s. We recall the basic ideas and confronts lapping practiced previously. Finally, we give some leads on trends in the design of CMM related to the introduction of sensors, the emergence of "microCMM" or three-dimensional comparator. This is to provide in a few pages, a panorama of the state of the main knowledge in terms of design and product evolution.

Optimizing step gauge measurements and uncertainties estimation

“…These measurement procedures are now used by the CETIM in the periodical verification of the CMM and allow us to quantify the different geometrical errors of the CMM [16,17]. The philosophy of this work was applied in the context of a gear measurement application which is COFRAC accredited since August 2010.…”
