Abstract

Micro-scale cutting experiments were conducted to study the machinability of three different engineering materials: 303 stainless steel, unhardened 52100 steel, and Inconel 718. To study the effect of ploughing and minimum chip thickness, experiments were conducted at a wide range of feedrates (0.25-2 μm/flute). Cutting forces were measured and chip morphology was also studied. New parameters are defined to quantify tool wear for micro-endmilling. The results show that tool wear characteristics are quite different in micro-machining, particularly at low feedrates where the effects of ploughing/rubbing and minimum chip thickness are significant.
