| Dry cutting with static cooling, which makes the pressed air ionized and ozonic, and keeps a special surrounding in the cutting area, is one methods of dry cutting and has the same effect as coolant. At present, researching on the technique is very little. So it is necessary to research on the dry cutting with static cooling, and to design for the mechanism. BT20 titanium alloy, which was developed by Russia and has the characteristic of small density and great intension, is an important material and one approximate a titanium alloy. In the traditional titanium alloy processing, because both cutting speed and tool life are lower, the cutting efficiency is lower. For those problems, here is researched turning titanium alloy (BT20) with the static cooling.On the base of completely researching on the actualizing condition and the crux of technique in dry cutting, titanium alloy (BT20) processing characteristic and theory of air discharge, design the mechanism which mainly contains mechanism of electric field, air pressed and electrical source, and choice the best static parameters, optimize tool and lathe. Using the mechanism turn titanium alloy (BT20), the experiment shows that dry cutting with static cooling has the same effect as normal cutting, and can resolve all the ills brought by coolant. It will be a very bright green manufacturing. At last, in order to use the technique appropriately, we analyze the data of the experiment, which mainly contains design parameters, tool abrasion, chip configuration, tool life, and the influence of cutting parameters on processing.This paper optimized the key parts, which are static field and lathe principal axis with Visual C++ software, this method which using computer aided design and analysis can apply to other lathe principal axis. |
