Effects of cooling air temperature and cutting velocity on cryogenic machining of 1Cr18Ni9Ti alloy
This paper presents experimental investigations on influences of cooling air temperature, as well as cutting velocity, on performance in milling of the lCrl8Ni9Ti alloy with coated cemented carbide inserts. Cutting force, tool wear and surface roughness are experimentally studied to compare the effects of different cooling air temperatures. The results showed that minimum quantity lubrication (MQL) with cooling air significantly reduces cutting force, tool wear. Three different cooling air temperatures are used to investigate the effects of cooling air temperature on the machinability characteristics of 1Cr18Ni9Ti alloy. Based on the experimental results, MQL with cooling air of -50°C provides more favorable effects compared to the other two cooling air temperatures (-10°C, -30°C). However, different cooling air temperatures have a slight effect on cutting force under the same MQL condition.
