To improve the machining precision of part surfaces and to facilitate tool design and cutting parameter selection, the initiation and propagation laws of glass cracks in specimens subjected to normal loading by symmetric wedges were investigated.
This paper presents a experimental method for the analysis of shrink-fit stresses(i. e. stresses Produced by shrink-fit) using the streas-freezing method in photoelastic. The content consists of four parts:similarity condi- tions and design of models, essential requirements for the machining of models, experimental steps and stress analysis.
This paper discusses the geometrical elements defining the precision of the spiral faces of a compressor rotor, and derives formulas for their calculation. Effects of various technological errors on the precision of the spiral faces have been considered. Checkout parameters and checkout methods have also been investigated. Original technological factors are analysed. Ways of improving the machining quality of screw compressor rotors have thus been indicated.
In order to ensure the meshing quality of hypoid gears, the parameters of adjustment for machining the gears must be accurataly calculated according to the profile structural elements of the gear pair. In this paper, the principle and methods for determining the profile structural elements and adjustment parameters are outlined.
