摘要

根据弧齿锥齿轮轮坯、刀盘及机床调整参数

建立了弧齿锥齿轮的三维加工模型。研究了金属切削加工有限元分析中所涉及的刀屑界面摩擦模型、刀屑接触定义、切屑分离准则等相关关键技术。建立了弧齿锥齿轮铣齿加工过程的有限元模型

通过ABAQUS软件仿真模拟出了不同工艺参数和刀具参数下的铣齿加工过程

得到了切削层形态及应力分布结果。研究结果表明:刀具前角增大

切削层变形减小

主切削力减小;切削速度增大

主切削力减小;刀具的合理前角应取为20°

切削速度应根据实际情况取较大值。同时也为选取和研究弧齿锥齿轮加工工艺参数提供了一套有效的方法。

Abstract

According to dimensions

cutter parameters and machining parameters of spiral bevel gears

spiral bevel gear machining 3-D models are established.Several key finite element analysis techniques of metal cutting processes

such as the separation criteria

the definition for interaction of cutter and chip

the friction mode

are studied.The finite element models of spiral bevel gears are established

and milling process of a tooth surface is simulated in different parameters.In addition

the shape and the stress of the cutting layer for results of simulation are analyzed.The results show that: the rake angle and cutting layer deformation increase

the main cutting force decreases;the cutting speed increases

the main cutting force decreases;the rake angle should be 20°

the cutting speed should be the faster one which is based on actual situation.It could be used to select and study the process parameters of spiral bevel gear milling process.
