摘要：为了提高螺旋铣孔的制孔质量，需要预测加工过程中的切削力大小规律。通过ABAUQS/Explicit求解器模块对螺旋铣孔进行试验验证，分析并建立了钛合金螺旋铣孔仿真中的一系列模型，提出综合位移分离法和能量分离法来定义材料的分离属性。针对螺旋铣孔的特殊运动路径，运用连接器与边界载荷条件协同模拟实现。通过仿真模拟得出螺旋铣孔加工中切削力的变化规律，同时分析了最大应力应变的属性和分布特点。

Abstract:To improve the drilling quality of spiral hole milling，cutting force prediction process，using ABAUQS/Explicit explicit analysis mode solver simulation of helical milling experiments.The establishment of a series of titanium alloy helical milling simulation in the column model is analyzed，a comprehensive method of separation and displacement the energy separation method to define the separation properties of materials is put forward.The special motion path of helical milling hole is simulated by using connector and boundary load condition.Through simulation，the change law of cutting force in spiral milling process is obtained.The attributes，distribution characteristics of maximum stress and strain are analyzed.
