Study of the Machining of Intake Valve Seats of Internal Combustion Engines

Autor: Siqueira, Ildeu Lúcio

Publikováno v: Repositório Institucional da UFU
Universidade Federal de Uberlândia (UFU)
instacron:UFU

The excessive vibrations are common during the chamfering of valve seats and induce operator to reduce cutting speed and feed rate, causing reduction of the productivity. The objective of this work was to study the chamfering of the intake valve seat
