PARAMETER OPTIMIZATION FOR TURNING EN 24 STEEL USING MINIMUM QUANTITY LUBRICATION (MQL)Pages 83-89
Abstract
The aim of the study is to investigate the effect of minimum quantity lubrication (MQL) on response characteristics during turning of EN 24 steel with CVD coated tungsten carbide (CCMT 090T308) insert. The turning experiments were carried out based on the Taguchi design of experiments. Turned surface was analysed with SEM image. Three input parameters such as cutting speed, feed rate and MQL flow rate were considered, carried out the turning operations, utilized the acquired results optimized the surface roughness, cutting force and cutting temperature. The results indicate that minimum quantity lubrication shows better performance over dry turning in terms of surface roughness, cutting force and cutting temperature.
Keywords: MQL,
