Titanium alloys are ideally suited for different manufacturing applications because of their unique combination of high specific strength over a wide range of temperature, in addition to excellent corrosion resistance properties. However, grinding of titanium alloys is quite difficult due to their high hardness at elevated temperature, low thermal conductivity and elastic modulus. Application of cutting fluid helps to improve grindability, but with the increasing level of environmental consciousness, new technologies have been required to address the problem. This investigation deals with application of alkaline soap water through an indigenously developed micro pump based cooling system during grinding of Ti-6Al-4V. Comparison has been made with dry grinding with respect to some response parameters such as grinding forces, specific energy, surface roughness, grinding chips and ground surface morphology. Results have indicated that grinding forces, specific energy requirement and surface roughness decrease with the application of the micro pump based system. Observation of grinding ratio, chip form and ground surface has shown favourable results. Therefore, this newly developed micro pump system may be recommended to supply soap water for grinding titanium alloys.

使用本地开发的基于环境的微型泵冷却系统探索Ti-6Al-4V的可磨性

钛合金不仅具有出色的耐腐蚀性，而且在很宽的温度范围内具有高比强度的独特组合，因此非常适合于不同的制造应用。然而，由于钛合金在高温下的高硬度，低导热率和弹性模量，因此很难研磨。切削液的应用有助于改善可磨性，但是随着人们对环境意识的增强，需要使用新技术来解决该问题。这项研究涉及在研磨Ti-6Al-4V时通过本地开发的基于微型泵的冷却系统施加碱性肥皂水。对于某些响应参数（例如，磨削力，比能，表面粗糙度，磨屑和地面形态。结果表明，随着基于微型泵的系统的应用，磨削力，比能量需求和表面粗糙度降低。观察磨削比，切屑形状和磨削表面均显示出良好的效果。因此，建议使用这种新开发的微型泵系统来供应肥皂水，以研磨钛合金。
