规定了使用高速钢刀具对钢和铸铁工件进行端铣的刀具寿命试验的推荐程序。可应用于实验室和生产实践。考虑刀具劣化主要由磨损引起的情况。制定工件、刀具、切削液、切削条件、设备、刀具劣化和刀具寿命评估、测试程序、记录、评估和结果展示的规范。

specifies recommended procedures for tool-life testing with high-speed steel tools used for end milling of steel and cast iron workpieces. Can be applied to laboratory as well as to production practice. Considers conditions under which tool deterioration is mainly due to wear. Establishes specifications for workpiece, tool, cutting fluid, cutting conditions, equipment, assessment of tool deterioration and tool life, test procedures, recording, evaluation and presentation of results.
