Al-Si A356 alloy was melted by an induction furnace at 850 ๐C. After degassing with argon, grain refiners and Al-Mg master alloy were added into the melt. The melt was stirred and poured at the temperature 800 ๐C into the cylindrical stainless steel cup. Then, cooling temperature at a different time was recorded by a data logger. The chemical composition of samples were analysed by emission spectrometer analysis. The samples were cut from the same positions and then grinding and polishing. After polishing, the samples were etched in a Keller’s solution of 5% H2O, 5% HF, 30% HNO3 and 60% HCl in order to reveal the grain boundary, and the final average grain size was determined by linear intercept method.

The objective of this study is to develop a process of treatment of the vibratory signals generated during a horizontal high speed milling process without applying any coolant in order to establish a monitoring system able to improve the machining performance. Thus, many tests were carried out on the horizontal high speed centre (PCI Météor 10), in given cutting conditions, by using a milling cutter with only one insert and measured its frontal wear from its new state that is considered as a reference state until a worn state that is considered as unsuitable for the tool to be used.
