This standard JB/T 54857-1999 specifies product quality grading requirements for indexable face milling cutters, including AQL values, RQL values, nonconformity classification, and life tests. It applies to face milling cutters produced in batches according to GB/T 5342, classifying products into three grades: qualified, first-class, and premium. Nonconformities are divided into Class B (three groups) and Class C, covering dimensions, surface roughness, hardness, cutting performance, etc. The life test specifies conditions such as machine tool, tool, workpiece, and cutting parameters, and provides life indicators. This standard replaces JB/T 54857-93 and is under the jurisdiction of the National Tool Standardization Technical Committee.
本标准JB/T 54857-1999规定了可转位面铣刀的产品质量分等要求，包括AQL值、RQL值、不合格分类及寿命试验。标准适用于按GB/T 5342成批生产的面铣刀，将产品分为合格品、一等品和优等品三个等级。不合格分类包括B类（分三组）和C类，涉及尺寸、表面粗糙度、硬度、切削性能等。寿命试验规定了机床、刀具、试坯、切削规范等条件，并给出了寿命指标。该标准替代了JB/T 54857-93，由全国刀具标准化技术委员会归口。
