A thin-walled spherical shell made of pure iron material is a key part precision physical experiments. Tool wear characteristics freeform surface parts are significantly different from those single-point turning due to the movement contact point between tool and workpiece, which affects form accuracy integrity workpiece. However, there lack comprehensive understanding in machining materials. Th...

Abstract Structures made of thin-walled shells are widely distributed elements in the environmental protection systems. In this connection, it is necessary to develop their effective and refined calculation. The point shell structures considered with a plane load initial position, deformed after j loading steps (displacement vector) adjacent (j + 1) step. displacement increments derivatives tak...

Thin-walled parts with curved surface are widely used in industrial applications and the high-quality machining is still a major problem because of low stiffness. By using machining-path obtained from design model thin-walled surface, accuracy requirement may easily not be met due to springback clamping deformation when process finished. It novel idea that mapping free-state clamped-state reali...

The paper analyzes the structure of technological fixtures for positioning and fixing large-sized thin-walled pyroceram shells as a factor affecting dynamic characteristics grinding system. solution to problem ensuring stability «mandrel-workpiece» subsystem is necessary increase efficiency shell machining in present conditions. Studying vibrations frequency spectrum system during has made it p...
