Description
Summary:Positioning deviations such as systematic and random errors lend a substantial influence to finish machining. In this article is carried a theoretical research of the uncertainty when determining the repeatability of positioning with standard methodology, regulated in ISO 230-2. It is carried out by simulating different levels of random deviation for the position reached and the number of points on the controlled axis. The laws of distribution are established on standard assessment of positioning repeatability and the relative share of uncertainty regarding the actual (set) random positional deviation.
