Abstract

After sintering, cemented carbide inserts are ground in order to improve the integrity of their edges, rake and flank faces. The importance of this step in the manufacturing chain of cemented carbide inserts is related to the influence of surface roughness on the friction in the cutting region and to the reduction of tool life due to edge chipping. Residual stresses must also be considered since they change insert surface properties, causing a reduction of its strength and eventual failure. These characteristics can be controlled by an adequate choice of grinding tool and parameters. Thus, a detailed investigation of the influence of these factors on the performance of the insert is important in order to properly design the manufacturing process and increase tool life. In this context, the acquisition of the multi-user equipment "CNC grinding machine for cutting insert preparation" has the goal of meeting the needs of the associated project (2015/15622-2) and offering researchers from other institutions and companies the possibility of conducting tests for the investigation and optimization of tool grinding processes as well as of developing new cutting tools. Being the first equipment of this type in a laboratory in the country, it is expected that topics related to the manufacture of cutting tools begin to be disseminated in academic and industrial environments, promoting partnerships at national and international level and supporting the growth of national tool manufacturing companies.
