Analysis and prediction of the accuracy of the location of geometric elements of products using the apparatus of screw calculus
A new approach is proposed to ensure the geometric accuracy of products, taking into account the sources of errors. The concept of a configuration geometric model of a dimensional chain of a product is introduced. Mathematical tools have been developed for analyzing and predicting the accuracy of the location of product elements in three-dimensional space based on it. Mathematical modeling was carried out using the apparatus of screw calculus. The proposed approach will ensure the accuracy of the key geometric characteristics of the product, and, consequently, achieve a high quality of manufacturing products and ensure their assembly.
