Due to its good mechanical properties, high specific strength, superior high and low temperature performance, and excellent corrosion resistance, titanium alloy materials are widely used in aerospace, biomedicine, ships and automobiles. However, since titanium alloy is a typical difficult-to-machine material, with the gradual increase in the proportion of titanium alloy materials in the aviation field, especially in the aircraft manufacturing industry, how to reasonably select cutting parameters, optimize tool structure and geometric design, and formulate optimal machining. The process has become an urgent problem to be solved in the production of titanium alloy CNC machining parts.
Aerospace products generally require small structure size, light weight and high precision, so there are more small and complex parts. Because some small parts have complex structure and low relative stiffness, the processing technology is poor, and mechanical processing is easy to produce deformation. The problem is more difficult to solve.
The future development trend must be combined with the technical information and experience in the field of titanium alloy machining. The theoretical discussion on the processing technology of typical titanium alloy parts is carried out, and the milling, drilling and boring in the processing of titanium alloy shell parts are mainly introduced. Hole, tapping and other processes, including sheet metal processing in practical applications, can provide certain help for front-line personnel in the field of titanium alloy CNC machining parts.
All in all, with the wide application of titanium alloys, due to its high material strength, high chemical activity, and low elastic modulus, the intractability of its materials has attracted more and more attention in the field of machining. Therefore, the technology of titanium alloy processing superalloy in CNC machining parts needs to be further promoted.
