ARITHMETIC MEAN HEIGHT AND MAXIMUM HEIGHT OF THE ROUGHNESS PROFILE IN HONING WITH DIFFERENT FEEDS

Abstract

The achievable surface quality is an important factor even in roughing procedures; however, it is most relevant in finishing. Two commonly measured and analysed characteristics of the machined surface roughness profile are the Arithmetic Mean Height and the Maximum Height of the Roughness Profile. In this paper these parameters were studied in bore honing. Cutting experiments were carried out, where the feed rate and the applied honing tool are varied. After the evaluation of the measured 2D surface profiles, the following conclusions were drawn: the effect of the feed rate is not linear; the lowest values of the analysed roughness parameters were achieved by the application of 50 mm/rev. feed rate and a honing tool with 80 grain size and ceramic binder; the difference between the studied roughness parameters was 6.5-8.0-fold.
