Abstract

Numerical simulations of honing process of thin-wall cylinder liners, with constant and with variable thickness of the wall of honed workpieces can improve and can help to conduct the experimental research of honing process and can improve the honing process. A very valuable research assumption, before performing the numerical analysis of computer simulation of honing process, is the measurement of the real geometry of the honing head using a CNC coordinate measuring machine and measuring of the honed workpiece’s temperature occurring in the honed workpiece during honing process with a thermal infrared camera. Thick-walled workpieces do not create machining and technological performance problems. In a predictable way, it’s possible to plan the machining time remaining to receive the desired diameter of the hole being honed. Deformations of a thin-walled workpiece with varying wall thickness occurring during honing, which were measured after machining, showed that there is no linear correlation of holes deformation received for a different crosssection thicknesses of wall of honed cylinder liners for various oilstone pressure and due to the workpiece temperature increase.
