The theoretical research objectiveis to create prerequisites for the development of new designs boring tools. task which paper is devoted: identification constructive varieties tools; improvement geometric shape conical part tool. Research methods: modeling elastic deformations various novelty work: a design with transitional section from prismatic in form cone and barrel-like proposed introduc...

Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation...
