This standard specifies quality grading requirements for keyway milling cutters, including AQL values, RQL values, nonconformity classification, and life tests. It applies to cutters produced according to the GB/T 1112 series. Products are classified into three grades: qualified, first-class, and premium, each with specific AQL and RQL values. Nonconformities are divided into Class B (three groups) and Class C, covering cracks, surface roughness, dimensional deviations, hardness, and other criteria. The life test specifies conditions such as machine tool, cutter, workpiece material, and cutting parameters, along with life criteria and indicators.
该标准规定了键槽铣刀的质量分等要求，包括AQL值、RQL值、不合格分类及寿命试验。适用于按GB/T 1112系列标准生产的键槽铣刀。标准将产品分为合格品、一等品和优等品三个等级，并针对不同等级设定了具体的AQL和RQL值。不合格分类包括B类（分三组）和C类，涵盖裂纹、表面粗糙度、尺寸超差、硬度等多项指标。寿命试验规定了机床、刀具、试坯、切削规范等条件，并给出了寿命判据和指标。
