摘要

为解决电弧机械组合铣削过程中的表面完整性和加工余量分布问题，以TC4钛合金为对象，研究电弧铣削（EAM）深度对重铸层厚度和表面粗糙度的影响，并分析重铸层的组织特征和表面形貌．对组合铣削和传统机械铣削的切削力、表面粗糙度和表面硬化进行分析．结果表明，电弧加工产生的重铸层硬度为313.21 HV．随着电弧铣削深度的增加，局部重铸层厚度和峰谷（PV）差值也随之增加．为确保有效去除表面缺陷，后续机械铣削的加工余量必须超过重铸层厚度和峰谷差的总和．参数相同的情况下，与单一机械铣削相比，组合铣削的表面粗糙度更高（0.584μm），表面硬化程度更高（10.4%），同时切削力增加了18.716 N．响应曲面（RSM）分析表明，每齿进给量是影响表面粗糙度的最重要因素，其次是主轴转速，铣削深度的影响最小．

Abstract

To address problems in surface integrity and machining allowance distribution during combined electric arcmechanical milling

this paper takes TC4 as the research object

examines the influence of electric arc milling(EAM) depth on recast layer thickness and surface roughness

alongside an analysis of the recast layer's organization characteristics and surface morphology. A comparative evaluation of cutting forces

surface roughness

and surface hardening is conducted between combined milling and conventional mechanical milling. Key findings reveal that electric arc machining produces a recast layer with a hardness of 313.21 HV. As the EAM depth increases

the localized recast layer thickness and peak-to-valley(PV) differences also rise. To ensure effective surface defect removal

the machining allowance for subsequent mechanical milling must exceed the combined thickness of the recast layer and the PV difference. Under identical parameters

combined milling yields higher surface roughness(0.584 μm) and greater surface hardening(10.4%) compared to mechanical milling alone

alongside an18.716 N increase in cutting force. Response surface methodology(RSM) analysis identifies feed per tooth as the most significant factor affecting surface roughness

followed by spindle speed

with milling depth having the least influence.
