Trajectory analysis and experiments of both-sides cylindrical lapping in eccentric rotation

International Journal of Advanced Manufacturing Technology, 2016
In this paper, the both-sides lapping in eccentric rotation is proposed to fine-finish the cylindrical surface of a batch of bearing rollers. The geometry and kinematics of the workpiece are theoretically analyzed, the trajectory on the cylindrical surface is simulated, and the trajectory distribution is evaluated quantitatively by calculating the ...

Investigation and optimization of the internal cylindrical surface lapping process of 440c steel

Journal of Mechanical Science and Technology, 2019
A new lapping method is proposed for internal cylindrical surfaces finishing. Regression analysis and artificial neural network (ANN) were used for modeling this lapping process and predicting the effects of parameters of rotational speed of the lapping tool (ω), the length of the lapping tool (L) and difference in external diameter of the lapping tool

Experimental study on double disc straight groove lapping of cylindrical rollers

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering
This paper presents a study on the double disc straight groove lapping (DDSGL) process for cylindrical rollers. The motion characteristics of cylindrical rollers during DDSGL were analyzed, and a theoretical model for predicting the surface roughness of the ground rollers was established.
