The Creation

The development of mechanical engineering in recent years has led to a special focus on the processing of functionally connected surfaces. In world practice, more attention is paid to the creation of methods, techniques, technological processes, tools, measures, etc., which would reduce the complexity of processing and assembling functionally connected surfaces (FCS) of details and connections. Currently, the connection between the dimensions and positions of surfaces is not standardized for all details. These details include body parts and frames that have V-shaped surfaces and associated planes. Apparently, this is due to the large variety of functionally connected surfaces and the complexity of controlling the technological support of dimensions. When coupling details of metal-cutting machines FCS, it is necessary to ensure simultaneous contact of two combined surfaces of the guides. This article provides a method for selecting the optimal layouts of the size limit deviations when assembling details with FCS. The influence of the location of the size limit deviations on the complexity of the fitting operation when assembling two combined surfaces of details is considered. Possible layouts of the size limit deviations are shown, as well as a diagram of the relative position of the two combined surfaces before the fit operation, depending on the values of the size limit deviations. Some recommendations are given for choosing the optimal layouts of the limit deviations of the dimensions of the adjacent planes: - the position of the adjacent planes depends on the size values and their deviations; - the position of the adjacent planes is significantly affected by the position of the size deviations of the connected planes; - depending on the location of the limit deviations of the size of the joints, the amount of removed allowance varies considerably and leads to a significant change in the labor intensity of the scraping process.
