Keywords: reconfigurable manufacturing systems; auto-replaceable assembly; transfer line pallet; flexible manufacturing system; multisided processing of parts; accuracy; stability.
Annotation: The article covers the issues of assurance of accuracy and stability of parts processing using the auto-replaceable assemblies and the repackaging of active position of reconfigurable manufacturing systems. The summing influence of auto-replaceable assemblies locating accuracy and their body stability on the accuracy of multisided processing of parts is demonstrated. To solve the issues of multisided processing of parts the author suggested the model of auto-replaceable assembly - carrier of parts for simulation of the issues of locating accuracy and carrier body stability assurance in active position of configurable manufacturing system. The author gives the design of a carrier made in the form of right prism on the lateral faces of which the basing holes are located, and the installation of the tool set and a part is carried out on each face. This construction assures the dimensional repetitive accuracy of the parts location relative to production assemblies of the active position and the equal carrier body stability in directions of multisided processing of the parts. The article describes the model of the system of equally spaced basing holes for simulation of carrier location accuracy. The effect of relative position of each carrier basing hole on the accuracy of the part processing is shown on the base of dimensional analysis. This aspect is determinant for carrying out multisided processing of the parts on the carrier. It was proved that the accuracy of multisided processing of the parts depends on the forced displacements of the carrier body arising due to overlap of variables of external force factors of machine processing. The author carried out the analysis of variety of force actions directions that allowed to determine the force factors and to speak about the study of optional designs of dimensional loading of the carrier body. The author considered the variable type of force loading f the carrier body as the aspect specifying the variable type of arising forced displacements during multisided processing of the parts. Thus, joint considering of proposed aspects of stability and locating accuracy assurance will allow to solve the problem of assurance of accuracy of multisided processing of parts on the carriers.
