There are lots of titanium alloy parts which have large-scale micro-structures in astronautic structure and medical implants, so the micro milling becomes one of the effective processing methods in getting the surface micro-structure. Because the titanium alloy has high caking property in processing, it needs a research on the cutting heat and force in order to get better machining precision and surface quality. According to the finite element theory in elastic and plasticity, the influence of cutting speed to the cutting heat and force is got by finite element simulation analysis to the titanium material TC4 in cutting process. It can get the simulation results of cutting heat and force in the micro milling processing by finite element analysis, and then compared, the basic influence which the cutting speed to the cutting heat and force is got. The correctness of the result is checked through cutting experiments.

The 3d model of miter gate has been set up based on skeleton model of Pro/E, and it has been imported into ANSYS Workbench module for static structure analysis and modal analysis. In the process of finite element simulation, the rotational constraints has been imposed on the top and bottom pivot according to the actual operation situation of the miter gate, and obtain the first several order frequencies and corresponding modal vibration mode of the miter gate, which can show the hydrodynamic vibration stress and strain distribution. According to the results of the finite element simulation analysis, the prototype vibration test of the miter gate has been done. The test results show that the vibration amplitude and the stress and strain distribution of each part of the miter gate are corresponding to the vibration test.

Elgiloy is a cobalt-based alloy with excellent physical and chemical performance, which is used widely in medical and industrial applications. In this paper, the professional finite element analysis software for metal cutting is used to establish the finite element simulation model of micro cutting this kind of cobalt-based alloy, and the effect of feed rate, which is considered as the most important processing parameter, on the cutting force of micro cutting Elgiloy is analyzed. The cutting force measurement system based on ultra-precision micro milling machine tool is established for experimental study on the cutting force of micro milling Elgiloy by using ultra-fine gain tungsten carbide micro milling tool. The cutting force is measured with different feed rate parameters and the influence of the parameters on the cutting force is analyzed. The simulation and experimental results show that the trends observed at the micro scale are the same as the trends for machining at the macro scale, which implies that the Elgiloy material behaves in a similar manner at both length scales.

The Relationship

Purpose This paper aims to predict tool wear and reveal the relationship between feed per tooth and tool wear in micro-milling Inconel 718 process. Design/methodology/approach To study and solve the tool wear problem in micro-milling of Inconel 718 micro components, in this paper, the investigation of micro-milling Inconel 718 process was implemented based on DEFORM finite element simulation, and tool wear depth of micro-milling cutter acted as output. Findings Different from the traditional macro milling process, diameter reduction percentage and average flank wear length decreased with the increase of feed per tooth; tool wear depth decreased when the feed per tooth was less than the minimum chip thickness. Originality/value At present, research on the prediction of tool wear in micro-milling of Inconel 718 has never been publicly reported. This study is significant to reveal the relationship between cutting parameters (feed per tooth) and tool wear in micro-milling Inconel 718.
