Abstract

The aim of study is experimentally investigate the influence of cutting speed, depth of cut and feed rate on surface roughness and cutting forces in high speed turning of monel k-500 in dry and MQL conditions. Cutting fluids have a reasonably low cost, their handling and carrying costs are very high and also, owing to their toxic nature, dumping of used fluids is a big problem because it can be hazardous to workers and also to the environment. To avoid these problems, a minimal-cutting-fluid technique called minimum quantity lubrication (MQL) was used in machining. The results indicated that MQL can decrease surface roughness 38 percent and it can decrease cutting force 59 percent.
