The nachinability is a propriety that depend of interaction between the process of manucfature and characteristic of piece material. At case of steels, the composition chemistry, the microstruture and the heat treating and mechanic, have one effect accentuated in machinability of this category of materials metallic. In present work of revision, macking reference criterions in appreciation of this propriety thought as the method of actuation of this agents machinability.
