This paper investigates the characteristics of a micro-scale end-milling process using the electro-hydro-dynamic (EHD) spray lubrication with chilly air. A new hybrid cooling and lubrication system was developed by integrating EHD spray and chilly air supply modules. In the experiments, the milling forces and burr formation are observed according to varying cooling and lubrication conditions. It is demonstrated that the developed new hybrid cooling and lubrication system can reduce milling forces and burrs significantly.

End Milling Process

This paper investigates the characteristics of micro end-milling process of titanium alloy (Ti-6AL-4V) using nanofluid minimum quantity lubrication (MQL). A series of micro end-milling experiments are conducted in the meso-scale machine tool system, and milling forces, burr formations, surface roughness, and tool wear are observed and analyzed according to varying feed per tooth and lubrication conditions. The experimental results show that MQL and nanofluid MQL with nanodiamond particles can be effective to reduce milling forces, burrs and surface roughness during micro end-milling of titanium alloy. In particular, it is demonstrated that smaller size of nanodiamond particles — 35 nm — can be more effective to decrease burrs and surface roughness in the case of nanofluid MQL micro end-milling.

Main Factor

During the milling operation, milling forces are the main factor to cause the machining deformation of the workpiece. The flow stress of Al 7075-T7451 was first described as a function of strain, stain rate and temperature in order to obtain the true behavior in machining process. Second, a finite element method of milling process of Al 7075-T7451 was developed to obtain milling force simulations. Finally, simulated results are compared with experimental data and are shown to be in good agreement with each other.

End Milling Process

The tool-workpiece contact zone is an important issue in the ball end milling process. This paper investigated the effects of tool inclination angles on the tool-workpiece contact zone, and variations of the cutting section area and perimeter with the increasing tilt and lead angles were also analyzed by geometrical modeling and measurement method for ball end milling process. The appropriate tool inclination angles, which could avoid the extrusion and friction between tool tip and the uncut materials, shorten the loading time on the cutting flute, and decrease the maximum cutting forces, could be preferentially selected according to the distribution characteristics of the tool-workpiece contact zone and the variations of the cutting section area and perimeter corresponding to various tool postures.
