The Issue of Contactless Setup before Measuring Process

Abstract

Increasing demands on productivity of measurement and control processes deal with high demands on speed, reliability and repeatability of all the preparatory steps that precede the measurement itself. These activities are still productivity needed and the productivity effect is multiplied by a technological downtime carrying them considerable economic impact, direct value added product. A typical case is the initial adjusting of the turntable of roundness instrument and measurement of the surface parameters in a hole with small diameter. This title deals with these issues.It describes the issue of compensation contact setting of roundness machine by contactless method including performance model and philosophy of determining measurement uncertainty. The initial proposal will be modified for specific task of CNC measuring parameters in the small diameter holes.
