In assembly operation of precision and tiny parts, like in watches, robots perform with accuracy and repeatability. As compact as a photoelectric sensor, the CMOS laser sensor allows to display actual measured distance as accurately as a displacement sensor. robot continues to be a single measure specified as something like “position repeatability accord- ing to ISO 9283”, which actually refers to the average unidirectional position repeatability at five poses obtained from thirty cycles and typically measured using a laser tracker. toe and Camber sensors are accurate up to. Published accuracy/ repeatability of Haas machines? Does anybody have a spec for the accuracy of these mills out of the box vs. g checking the fatigue life or checking the weld strength. In the case of a capacitive sensor with capacitance of 1 pF, the measurement repeatability should be less than 0. e MSA or repeatability & reproducability ) in case of destructive testing e. The main measurable characteristics are repeatability and accuracy.
