Abstract Tapping torque test is a standardized (ASTM D5619-00) approach evaluating the lubricity of metalworking fluids. It was detected that running-in behaviors of taps and carryover effects caused by previously used fluids were not investigated. Further, it is detected that effects due to changed tap conditions or fluids are underestimated. The low number of measurements leads to deviations of torque means. In this contribution, the running-in phase of coated forming taps is evaluated by measuring tapping torque in AlMgSi1, C45E, and AlSi7Mg materials using water-mixed metalworking fluids. New tests and calculation methods considering tool wear are suggested. As outcome increased experimental significance at higher confidence levels, comparability between taps and test platforms, and better distinguishability of water-mixed metalworking fluids are obtained.

根据 ASTM D5619 使用涂层成型丝锥和水混合金属加工液改进攻丝扭矩测试的检查和测试程序

摘要 攻丝扭矩测试是一种评估金属加工液润滑性的标准化 (ASTM D5619-00) 方法。检测到水龙头的磨合行为和由以前使用的流体引起的残留影响没有进行调查。此外，检测到由于改变的龙头条件或流体引起的影响被低估。低测量次数导致扭矩平均值的偏差。在此贡献中，通过使用水混合金属加工液测量 AlMgSi1、C45E 和 AlSi7Mg 材料的攻丝扭矩来评估涂层成型丝锥的磨合阶段。建议考虑刀具磨损的新测试和计算方法。随着结果在更高置信水平下增加实验意义，抽头和测试平台之间的可比性
