Influência do quebra cavaco e da seção transversal no torneamento de ferro fundido nodular

Abstract

The objective of this work is to analyze the influence of carbide cutting tools with chip breaker and the influence of section transversion, the result will discuss about the wear and formation chip in turning of nodular cast iron. The analysis will be in a pre-set batch in wheel hubs by the company Castertech. After the tests, the wear that each insert presented was idenfied, relating to the type of chip breaker. As a result, it can be identified that the insert with more aggressive chip breaking had a higher side edge wear, but in the upper part the chip breaking helped to reduce wear, due to better chip evacuation. In terms of chip formation it can be seen that the use of chip breaking, in nodular cast iron there was no great effect, because in this article the turning was an interrupted cut. n terms of economic feasibility, you realize that the chip breaking inserts from Korloy manufacturer obtained a better cost per edge and per piece due to the fact that these inserts have a lower price compared to the other tested manufacturer.
