与传统的冷却润滑策略相比，低温加工具有优势，特别是对于钛和镍合金等难切削和耐高温材料。为了实现的目的，环境和成本因素是至关重要的，这种新的加工方法在批量生产。为了促进投资，在作出最后实施决定之前，必须评估技术的潜力。在机械加工领域，特别是利用低温工艺冷却的机械加工领域，没有标准化和统一的程序来评估这种潜力。本文将介绍一种系统的方法和基本的分析工具，以确定在资源和能源效率的制造操作方面的低温处理的潜力。这种方法在合理的评估工作中以及在细节水平上满足一般条件。利用这一分析工具，将真实的生产和工艺数据与科学低温试验和研究结果进行比较，并检查其适用性。因此，可以在生产的早期阶段确定制造中的潜力，并采取措施实现这些效果。如果到目前为止尚未对特定材料进行低温处理，则确定该材料与现有研究结果的相似性。如果评估结果为肯定，则替代品的潜力将以特定的安全系数转移到材料中。该分析工具已在一个真实的大规模批量生产以及一个复杂的组件制造中得到应用和改进，并为电子商务的整体潜力。G.已经确定了与使用金属加工液（MWF）有关的耐久性、材料去除率（MRR）或节约。
Cryogenic machining offers advantages compared to conventional cooling lubrication strategies particularly for difficult-to-cut and high-temperature-resistant materials such as titanium and nickel alloys. For implementation purposes environmental and cost factors are crucial for this new machining approach in series production. In order to facilitate investments it is mandatory to evaluate the technology’s potential prior to the final implementation decision. In the field of machining, in particular machining with cryogenic process cooling, there is no standardized and uniform procedure to assess this potential. In this paper a systematic approach and underlying analysis tool will be introduced to determine the potential of cryogenic processing in terms of resources and energy efficiency of the manufacturing operation. This approach satisfies the general conditions in a reasonable assessment effort as well as in the detail level. With this analysis tool, real production and process data are compared with results from scientific cryogenic tests and research and examined with regards to their applicability. Thus, it is possible in an early stage of the production to identify potentials in manufacturing and to take measures to realize these effects. In case cryogenic processing of a specific material has not been carried out so far, the similarity of this material to existing research results is determined. If positively assessed, the surrogates’ potential is transferred with a specific safety factor to the material. The analysis tool has been applied and refined in a real large-scale series production as well as in a complex component manufacturing and the holistic potential for e. g. durability, material removal rate (MRR) or savings regarding the use of metal working fluids (MWF) have been identified.
