Analysis of surface roughness and chip cross-sectional area while machining with self-propelled round inserts milling cutter

摘要

An interesting development in the field of machining is to improve the cutting tool performance by providing continuous indexing to the cutting edge actuated either by cutting velocity vector or by an external power. This paper presents an analysis of cutting process performed using a specifically designed and fabricated self-propelled rotary inserts face milling cutter. Statistically designed experiments were performed using Taguchi method with surface roughness and chip cross-sectional area as response variables. Analysis of experimental results using analysis of means and analysis of variance is discussed in detail. It is observed that inclination angle is the most significant factor influencing both surface roughness and chip cross-sectional area and can give better results in the range of 30–45°.
