Abstract Titanium alloy has been applied in the field of aerospace manufacturing for its high specific strength and hardness. Nonetheless, these properties also cause general problems machining, such as processing inefficiency, serious wear, poor workpiece face quality, etc. Aiming at above problems, this paper carried out a comparative experimental study on titanium milling based CAMC BEMC. Th...

With the rapid development of high-precision-device technology, new demands are put forward for micro milling. The size effect and low cutting energy milling make process expensive difficult, especially Ti-6Al-4V alloys. wear micro-milling cutter lacks corresponding international standards its mechanism is complex. In this paper, four kinds cutters with different states were obtained by designi...

High-speed machining of γ-TiAl alloy is a significant challenge due to high cutting temperatures. From the perspective environmental protection and improving tool life, appropriate cooling strategies should be adopted. Compared with dry conventional flood conditions, feasibility in cryogenic LN2 conditions was discussed. The force, wear its mechanism, surface roughness, as well sub-surface morp...

This paper presents the performance evaluation of three different cutting fluids used in a minimal quantity lubrication (MQL) system. The MQL system, developed in-house at the University of Malaya, was capable of delivering high velocity cutting fluid in narrow pulsed jet forms at a rate of 2 ml/min and a pressure of 20 MPa. The three cutting fluids chosen were neat oil, soluble oil and semi-sy...
