Titanium alloy with a high specific strength and good hot strength , corrosion resistance , resource-rich series of advantages , widely used in aviation, aerospace , marine , and other industrial sectors . Because of its small thermal conductivity, chemical activity , cutting deformation coefficient , friction coefficient and chip on the rake face contact area is small reason , makes titanium alloy processing , cutting temperature , cutting power units , and serious tool wear limit its further promotion and use . Plunge milling method , also known as the Z-axis milling , is one of the most effective processing methods to achieve high removal rate of metal cutting , especially for difficult to cut materials removal rate advantage . Therefore, titanium alloy Ti -6Al -4V as the research object , tool plunge milling process , the cutting performance of four different manufacturers conduct experimental research, and application of the theory of fuzzy mathematics , fuzzy comprehensive evaluation of the four tool performance . First , according to the characteristics of plunge milling milling way to build a test platform , measuring the titanium alloy plunge milling process , the cutting force , vibration and blade wear and other physical phenomena . Secondly , the research and to design a set of test and analysis system based on virtual instrument technology plunge milling process of cutting temperature , silk semi- artificial thermocouple titanium milling zone temperature measurement with cutting parameters with cutting parameters cutting temperature the variation of the experimental study . Further, the conditions Cutting Temperature Measurement attempt. Finally , based on the theory of fuzzy mathematics considering various influencing factors , milling insert cutting performance fuzzy comprehensive evaluation model , the use of two fuzzy comprehensive evaluation , the evaluation process takes into account not only the cutting temperature , cutting forces , wear , vibration factors evaluation at all levels and retain all the information to make the evaluation results more realistic . The above results for titanium alloy plunge milling process provides an important reference tool selection and cutting parameters process optimization .
