Improvement of the planes accuracy of the thin-wall casing parts at a high-speed treatment due to reducing the elastic deformations of the walls to be treated at rotary milling

The purpose of the work: improvement of accuracy of the treated planes form of the thin-wall aluminium casing parts at a high-speed rotary milling due to reducing the walls elastic deformations in the course of processing. The theoretical investigations of elastic deformations on the base of the theory of thin plates elasticity under the pulse force action have been carried out. The experimental investigations have been performed on the method of planning the multifactor experiments. The deformation measurements have been performed using the inductive transmitters. It has been offered to determine the deflection value from the flatness as from the action of axial force so from the action of this force pulse. The versions of models of the thin-wall casing parts allowing to design the elastic bends and deviations from the form have been developed. The particular force dependences have been determined for the cutting forces at a rotary milling ALCH and D16T, the tables on selection of the milling cutters tooth number have been developed. The algorithm and the design program of the treatment error and selection of cutting conditions have been developed on the computer. The results of the theoretical and experimental investigations can be used in the autotractor-building in treatment of the thin-wall casing parts as well as in the study processAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
