Abstract
A new algorithm for determining internal losses in relation to engineering products is presented, mathematical dependencies are given for estimating of the categories of internal losses. On the example of the production of crankshafts, a classification of internal losses from defects is developed, the selection of quality control tools for registering types of defects and their further analysis is substantiated. A new form of a checklist is developed for recording non-conformities and losses from rejects. The final assessment of internal losses was carried out according to quantitative and cost criteria using the Pareto diagram. Keywords: internal losses, defects, repairable reject, irreparable reject, checklist, Pareto diagram, methodology for estimating of internal losses. metr@rgau-msha.ru
