摘　　要：某差速器壳体产品在铰削十字孔的过程中,加工尺寸不稳定、刀具磨损较快且磨损后期孔壁划痕严重,使用寿命也普遍较低.通过按照国标计算出合理的铰刀直径公差范围,对比经验数据并考虑经济因素,选取铰刀的几何参数和计算经济刀具寿命。统计分析了批量加工的壳体十字孔直径数据与刀具寿命,确定了影响刀具寿命与加工质量的主要因素并对其进行改进实验验证,铰刀寿命提高了1倍多,大大降低了刀具使用成本。In the process of reaming the cross hole of a differential mechanism housing product,the machining size is unstable,the tool wear is fast,and the hole wall is severely scratched in the later wear period,and the tool life is generally low.The reasonable tolerance range of reamer diameter is calculated according to the national standard,and the geometric parameters of the reamer are selected,and the economic tool life is calculated by comparing the empirical data and considering the economic factors.The diameter data of the batch processing housing product and tool life are statistically analyzed,the main factors affecting the tool life and processing quality are determined,and the improvement experiments are carried out to verify that the reamer life is doubled,the tool cost is greatly reduced.
