Abstract

Machining performance of 5 wt.% silicon carbide particulate reinforced Al 7075 matrix composite was investigated in terms of cutting tool temperature (T), average surface roughness (Ra) and tool flank wear (VBc) during turning in pollution-free air water spray cooling environment. Metal was removed by multiple layers of TiN coated carbide inserts during turning. Nonlinear regression models were developed and their adequacies were verified. Significance of process parameters on the responses was investigated through analysis of variance. The responses were optimized individually using Taguchi technique and then simultaneously through particle swarm optimisation technique. The proposed multi-objective algorithm outperformed the traditional Taguchi approach and effectively resulted to a group of non-dominated solutions. Pareto optimal fronts were compiled and plotted for T, Ra and VBc, which can be selected according to the production requirements.
铝基金属基复合材料的加工——粒子群优化方法
研究了5 wt.%碳化硅颗粒增强Al 7075基复合材料在无污染空气水喷冷环境下车削过程中的刀具温度(T)、平均表面粗糙度(Ra)和刀具刃口磨损(VBc)。在车削过程中,金属被多层TiN涂层硬质合金刀片去除。建立了非线性回归模型,并验证了其有效性。通过方差分析考察工艺参数对反应的影响。分别采用田口法和粒子群法对响应进行优化。提出的多目标算法优于传统的田口法,能有效地得到一组非支配解。编制并绘制了T、Ra和VBc的帕累托最优战线,可根据生产要求选择。

期刊介绍: IJMMM is a refereed international publication in the field of machining and machinability of materials. Machining science and technology is an important subject with application in several industries. Parts manufactured by other processes often require further operations before the product is ready for application. Machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations - turning, milling, drilling and grinding, for example. Machining processes can be applied to work metallic and non metallic materials such as polymers, wood, ceramics, composites and special materials. Today, in modern manufacturing engineering, there has been strong renewed interest in high efficiency machining.
