Optimization of Processing Modes on Multioperational Machines Using Two-parameter D-Partitions

Stability, vibration-free processing of various products types on multioperational machines indicates an improvement in research in the field of machine dynamics and their main forming units. Three-dimensional models of the forming units for multioperational drilling-milling-boring machine in the CAD-KOMPAS-3D environment have been developed. An algorithm for analyzing the dynamic quality of machines elastic parts based on the constructed model of a two-mass system in the form of a second-order differential equations set is proposed. The transfer function of the disturbing force is obtained and the structural diagram of the machines technological complex is presented. A procedure for the experimental determination of the static and frequency formulars in the MAPLE mathematical environment is proposed for a milling machine of the second standard size. The obtained forms allow you to control the process of forming using a wide range of tooling. An algorithm for assessing the vibration resistance of a multioperational machine based on the two-parameter D-partitions method is presented. The region and the boundary of the machine stable functioning were found and, based on this, the optimal processing modes were identified by the criterion of vibration resistance. The results obtained make it possible to control the cutting process at the boundary of the maximum capabilities of a multioperational machine in terms of its dynamic quality.
