Filtering effects on involute gear form measurement

Abstract Traditional gear measurement results are used to classify a tolerance grade in accordance with ISO 1328-1:2013 but as more stringent requirements placed on performance it is important also characterise related features properly the flank surface. However, uncertainty of machines not improving at same rate requirements, and uncommon have less than 10 μm tolerances be measured 1–3 capability. This breaks ‘rule thumb’ that should smaller one tenth value you trying measure. It therefore review evaluation process identify if there any areas for improvement within our current methods. Additionally, measurements being refine tooth contact analysis models development optical high speed tactile scanning methods allowing full 3D surface feasible option shop floor. Greater understanding involute beyond standard limits thus required. These additional prompted this effect Gaussian filters specified their characteristics fully understood by those who must perform interpret results. paper examines these where micro geometry corrections, such tip relief, or end face chamfers present. Methods minimising effects reviewed specific reference strategies defined 16610-28:2016. Recommendations offered minimise when evaluating class quantifying geometry.
