摘要

电火花线切割齿轮加工在制造业中占有重要地位。介绍了在黄铜工件(10cmx15cmx6mm)上采用线切割加工工艺加工黄铜直齿轮的工艺参数分析与优化。采用实验设计法(DoE)进行实验，采用响应面法分析材料去除率(MRR)。研究了输入参数即脉冲开启时间、脉冲关闭时间和进给速率对MRR的影响。用扫描电子显微镜(SEM)分析了齿轮的表面几何形状。研究发现，当脉冲开启时间为0.4 μs，脉冲关闭时间为60 μs，进料速度为6 mm/min时，材料去除率提高。方差分析表明，脉冲时间和进给速度是影响线材电火花加工的重要参数。SEM图像显示了电火花线切割加工具有均匀分布的规则形凹坑和无缺陷齿面的微型齿轮的能力。

The analysis of material removal rate of WEDM miniature gears

Gear fabrication in wire electrical discharge machining (WEDM) plays an important role in manufacturing industries. This paper describes the analysis and optimization of process parameters for the fabrication of spur gear on brass spur gear on brass workpiece (10cmx15cmx6mm) material by wire EDM process. The experiments were performed by using the design of experiment (DoE) approach and the material removal rate (MRR) was analyzed by response surface methodology technique. The effect of input parameters i.e. pulse on time, pulse off time and feed rate on MRR has been investigated. The surface geometry of the gears has been analysed by the Scanning Electron Microscopy (SEM). This study found that 0.4 μs for pulse on time, 60 μs for pulse-off time and 6 mm/min for feed rate provides improved material removal rate. The analysis of variance shows that pulse on time and feed rate are the significant parameters for the wire EDM process. The SEM image exhibits the capability of WEDM to machined miniature gear with a uniform distribution of regular-shaped craters and defect-free flank surface.

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
