Abstract
An airplane has about 6-million components and parts, mainly the engine, undercarriage, constructions and so on. Among them, nickel base materials are widely used, including engine, cartridge receiver, compressor drum and other industries application, such as energy, petrochemical industry, mould, etc. Nickel base alloy, with anti-corrosion and thermo stability, has good mechanical properties under high temperature. Since 1950s, due to the development of precision casting technology, a series of cast nickel base super-alloy with high strength has been developed, namely the super-alloy complying with the above conditions. In recent years, with the changing of military and civil aerospace, the usage amount of nickel base super-alloy also increases along with the date. This research mainly used Waspaloy of nickel base material to do cutting research and uses regression analysis to find significant factor of cutting tool's life, and performs the optimization experiment. The cutting research mainly uses TiAlN to coat cutting tools. In the conclusion, it discusses main factors that influence the tool life, such as the cutting speed, depth, feed rate and so on. Finally it establishes tool life formula with regression analysis method, in this case when cutting speed V = 30.77 m/min and cutting depth dp = 0.0367mm, the minimum wear prediction can be obtained.
Highlights
Recent industry and research used semi-circular inductor to heat the titanium alloy Ti-5553 [12]
It can be seen that the cut ability had obvious difference and importance when there is no additional heat source to preheat, while the performance of cutting tool is very important during the cutting processing, On the 650e750 C has the increase of temperature will cause decreasing strength, as shown in Fig. 1 [6]
From the cutting tool life model, it can be found that cutting speed, depth, and feed rate were 100%, the ratio influencing the tool life were 70%, 27% and 37% [4]
Summary
Recent industry and research used semi-circular inductor to heat the titanium alloy Ti-5553 [12]. It can be seen that the cut ability had obvious difference and importance when there is no additional heat source to preheat, while the performance of cutting tool is very important during the cutting processing, On the 650e750 C has the increase of temperature will cause decreasing strength, as shown in Fig. 1 [6]. The abrasion of cutting tools will direct influence processing efficiency and precision. Response Surface Methodology (RSM) can be applied to WC-Co cutting tool without coating. In the life establishment of Titanium alloy Ti-6AL-4V cutting tool, dry cutting and end mill were used. Response Surface Methodology (RSM) uses statistical method to assist to solve the relation between multi independent variables and certain response variable in the unknown function, which combine experimental design and regression analysis, and through the experimental design method, in the space we set to input parameter, and get the required response value and its corresponding input parameter position. The following two restrictions exist: 1. It is suitable for continuous system, which is based on the assumption that the measurement scale of response value and independent variable is
