Evaluation of a Function Oriented Optical In-Process Measurement System for Cylinder Liners: 100 Measurement of the honed surface

摘要

Nowadays the honing process of cylinder liners for combustion engines is monitored by 2D tactile measurements of the honing structure. The problem of tactile measuring is the required offline measurement of the cylinder blocks, which results in increased handling efforts and costs. In this paper a method is introduced which overcomes this disadvantage by applying an inline optical measuring system for 100% in line measurement of the honed cylinder liner surfaces. Focus is the comparison of two optical sensors, working after the principle of chromatic aberration and a fiber based white-light interferometer.
