On deformation of thin-walled parts while turning on the lathes
Engineering Education # 02, February 2014
DOI: 10.7463/0214.0700319
The paper studies the overall picture of deformation of thin-walled parts while turning them on the lathes. Its objective is to define configuration and value of the process-induced deformations under turning conditions of mechanical engineering. The paper investigates the parts of class “tube” and “disk”. A solution of the problem under consideration uses computer simulation in ANSYS software environment. The study task is to estimate the prospects for concept development to machine the thin-walled parts with controlled deformation under “soft” turning conditions. The simulation has shown that the change of turning conditions within the studied intervals causes changing deformations of parts in the range from 0.1 to 3 values of tolerance zone. This result can be a basis to plan further activities in the field concerned.
Synthesis method for spinning flasks made of composite materials as part of the product life cycle management concept
Engineering Education # 08, August 2012
DOI: 10.7463/0812.0434726
All elements of inconsistencies and contradictions between the stages of production of composite cylinders by method of spinning were considered in detail. It was established that solution of occurring conflicts is possible in the case of unified information approach in accordance with the concept of product life cycle management. The authors propose a technique of creating the proposed system and the example of its work in the special case.
