The fabrication of microchannels, in order to dissipate the heat flux generated in the complex parts of an electronic industry, requires considerable attention since it is a complex process. Some advanced machining process like wire electrical discharge machining (WEDM) has been employed carefully for forming channels in material. However, the surfaces of these microchannels play an important role in dissipating heat energy. The present study focusses on the fabrication of AA6351/10[Formula: see text]wt.% Rutile MK grade mineral through powder metallurgy route, and their properties are evaluated. In addition, the forming of microchannels on the fabricated composite has also been done through WEDM process under varying machining conditions. WEDM process conditions considered are current, voltage and wire speed, and the response characteristics are kerf width, surface roughness and kerf depth. The hybrid approach of gray-based Taguchi coupled with PCA has been considered for optimizing the process parameters so as to get near net shape channels. The determined hardness of the composite is 64.5[Formula: see text]HB and the compressive strength is 220[Formula: see text]MPa. The optimized conditions are predicted and the regression model has been developed.

用电火花线切割在 AA6351/金红石复合材料中产生的微通道的测量

为了消散电子工业复杂部件中产生的热通量，微通道的制造需要相当多的关注，因为它是一个复杂的过程。一些先进的加工工艺，如电火花线切割加工 (WEDM)，已被仔细用于在材料中形成通道。然而，这些微通道的表面在散热方面起着重要作用。本研究的重点是通过粉末冶金法制备AA6351/10[公式：见正文]wt.%金红石MK级矿物，并对其性能进行评价。此外，在制造的复合材料上形成微通道也是通过电火花线切割工艺在不同的加工条件下完成的。考虑的 WEDM 工艺条件是电流、电压和线速，响应特性为切口宽度、表面粗糙度和切口深度。已经考虑将基于灰色的Taguchi与PCA相结合的混合方法优化工艺参数以获得近净形状的通道。复合材料的测定硬度为64.5[公式：见正文]HB，抗压强度为220[公式：见正文]MPa。预测了优化条件并建立了回归模型。
