Abstract
Among the wide range of manufactured complex-profile products, gear wheels occupy a special place in the production process. The quality level requirements imposed on gears and determining their performance are difficult to establish and require special high-precision and expensive equipment based on computer systems. At the same time, many enterprises use universal coordinate measuring machines as instruments for monitoring linear dimensions, which have high accuracy, but are not intended for monitoring the quality indicators of gears. The purpose of the work is to expand the capabilities of these coordinate measuring machines based on the evaluation of gear indicators. The analysis shows that one of the reasons for refusing to use universal coordinate measuring machines is the coordinate control method implemented on them, which is not currently recommended for determining the quality indicators of gears set out in regulatory documents. The attempt presented in the article to substantiate the possibility of using universal coordinate measuring machines is based on assessing the acceptable risk of decision-making when assessing the quality of gears manufacturing. The technique is based on the principles of selective control on an alternative feature. According to this technique, an attempt was made to discretely represent the parameters of the continuous flank surface of the teeth, taking into account their manufacturing technology. Based on the acceptable risks of decision-making, the number of necessary coordinate sensing points of the surface was determined. In this case, the location of control points depends on the size of the given surface. Additionally, recommendations have been developed for transforming measurement results into normative indicators. The results obtained make it possible to recommend the use of universal coordinate measuring machines to assess quality indicators in the considered range of basic parameters.
