Abstract

In this experimental work, a comparison between analytical model and experimental analysis on minimum cutting thickness and surface roughness in a CNC micro turning of aluminium 19000 alloys has been investigated. Prior to machining, a 30 mm thick electroplating was done on the work samples. Machining parameters such as cutting speed, feed and depth of cut were taken as the input parameters while the minimum cutting thickness and surface roughness were the output responses. The machined surfaces of electroplated samples were examined for surface topology, initial and final diameter was also measured. Taguchi techniques were used to optimize the machining parameter. It was found that for the same machining conditions and tool geometry, the minimum cutting thickness and surface roughness were less for the electroplated materials compared with that of unplated material. In addition, the variation results of analytical model and experimental run were within the acceptable range. The analytical results were in a close tolerance with that of experimental results.
