With regard to the manufacturing of innovative hard-machining super alloys (i.e., Inconel-800), a potential alternative for improving the process is using a novel cutting fluid approach. Generally, the cutting fluids allow the maintenance of a better tool topography that can generate a superior surface quality of machined material. However, the chemical components of fluids involved in that process may produce harmful effects on human health and can trigger environmental concerns. By decreasing the cutting fluids amount while using sustainable methods (i.e., dry), Near Dry Machining (NDM) will be possible in order to resolve these problems. This paper discusses the features of two innovative techniques for machining an Inconel-800 superalloy by plain turning while considering some critical parameters such as the cutting force, surface characteristics (), the tool wear rate, and chip morphology. The research findings highlight the near-dry machining process robustness over the dry machining routine while its great potential to resolve the heat transfer concerns in this manufacturing method was demonstrated. The results confirm other benefits of these methods (i.e., NDM) linked to the sustainability aspects in terms of the clean process, friendly environment, and permits as well as in terms of improving the manufacturing characteristics.
关于创新型难加工超级合金（即因科镍合金800）的制造，改进加工工艺的一种潜在替代方法是采用新型切削液方法。一般来说，切削液有助于保持更好的刀具形貌，从而使加工材料获得更高的表面质量。然而，该加工过程中所使用切削液的化学成分可能会对人体健康产生有害影响，并引发环境问题。通过采用可持续方法（如干式加工）减少切削液用量，近干式加工（NDM）将成为可能，以解决这些问题。本文讨论了在车削因科镍合金800超级合金时两种创新加工技术的特点，同时考虑了一些关键参数，如切削力、表面特性（）、刀具磨损率和切屑形态。研究结果突出了近干式加工工艺相对于干式加工常规方法的稳健性，同时证明了其在解决该制造方法中传热问题方面的巨大潜力。结果证实了这些方法（即NDM）在清洁工艺、环境友好、许可等可持续性方面以及在改善制造特性方面的其他益处。
