Coordinate measuring arms – different methods of points collection

This paper deals with different methods of points collection using coordinate measuring arm. The research is divided into two parts. The first one is about measuring an aluminum cube with different geometric features with the use of hard probe and laser scanner. For the analysis some features and some resulting parameters were applied, like angle between two planes. As the reference, data from CMM measurements is used due to obtain higher level of accuracy of device. In the second part, a Teflon cube was used for the measurement. As this is a softer material than aluminum, measuring force gives significant impact on the results. To verify this, hard and triggering head was used.
