Machining is one of the most important processes for metalworking industries. Machining processes involve large quantities of variables that interfere with the results obtained. As variables, the cut-off parameter is defined as the tool's life-span, being defined as input variables and as the base material of the part and tool. Although these tooling parameters are influenced by the cutting forces, vibrations, acoustic emissions and temperature, this is due to variations in the types of wear and damage of the tools, surface finishing of parts, costs and machining times. All the information is important when using ceramic tools that constitute a technology in the maturation process for applications in heat resistant alloys. The growth and applications of cutting tools for ceramic materials can be a solution in the machining of new materials such as cast iron, nickel superalloys, hardened actions among others. To achieve the goal of great importance related study, to this follow-up, with emphasis on the control and compared in the machining processes of the implicit variables of the process. In recent works with advanced authors not developed in new cutting tools with important improvements of their properties and / or with unique properties. The advances achieved in the segment have enabled the diversification of applications in several materials, making possible the application of future applications as spin-off. The objective of this work is to apply the Al2O3 based tool developed with national technology without turning vermiculite (CGI) without the use of cutting fluid and analysis of the influence of shearing force without wear of the ceramic tool. Six different groups of parameters were used, where each group contains a replica of the assay. As tools were photographed by a ZEISS magnifying glass and analyzed for material wear. In the final analysis, ... (Complete abstract click electronic access below)
