Turning process monitoring of internal combustion engine piston’s cylindrical surface

Abstract

Abstract. In this paper the monitoring method of turning process of combustion engine piston's cylindrical surface is proposed. During this process, the PCD diamond tool cuts the piston's cylindrical surface with the 3 grooves. The first groove is made in the cast iron insert. In case, when the machining allowances are selected inappropriately, the tool cuts the cast iron insert and consequently generates the reject. The proposed monitoring system based on vibration signals analysis enables the detection of these critical situations and react, in order to maintain the production quality.

Influence of Electrode Material on Surface Roughness during Die-Sinking Electrical Discharge Machining of Inconel 718

“…With traditional machining of such materials, it is difficult to ensure adequate surface roughness [4]. Ensuring adequate roughness and properties of manufactured parts is extremely important from the point of view of performance [5,6].…”

Performance Analysis of Diamond Coated End Mill during Machining of Metal Matrix Composite

“…The other method of improving the efficiency of machining of hard-tocut materials is various kind of prediction models of tool wear. During the monitoring of machining process, the information about tool wear is useful for the tool condition prediction process [12]. There are a lot of methods of edge wear indicator prediction, where the following are the most interesting: genetic algorithm, artificial neural networks or fuzzy logic.…”
