I. Introduction
Gprinding is a machining process of great importance for manufacturing of mechanical components made from metals and ceramics. It is usually employed at the final stage of the manufacturing chain, in which there is already a high added value due to other manufacturing processes such as turning, milling and drilling. This process is very complex mainly due to several factors such as poor thermal conductivity of the cutting tool, randomly-distributed abrasive grains of the grinding wheel that are in contact with the workpiece and small section of chips [1].
