State of mechanical condition applied to industrial machines based on SVD method
(Universidad de Tarapaca, 2018-01-01)
A problem related to the operation of industrial machines has been the identification of the mechanical condition in exploitation, via dynamic performance variables which affect the nominal behavior of machine tasks. This ...
Feature extraction using frequency spectrum and time domain analysis of vibration signals to monitoring advanced ceramic in grinding process
(Inst Engineering Technology-iet, 2019-01-01)
New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...
Checking Completeness of Tests for Finite State Machines
(IEEE COMPUTER SOC, 2010)
In testing from a Finite State Machine (FSM), the generation of test suites which guarantee full fault detection, known as complete test suites, has been a long-standing research topic. In this paper, we present conditions ...
Green ceramic machining benefits through ultrasonic-assisted turning: an experimental investigation
(2022-02-01)
Machining of advanced ceramics in the green state aims to achieve complex geometry with near-net-shape dimensions minimizing machining steps after sintering, good surface finish, economic efficiency and flexibility, and ...
Turning of compacted graphite iron using commercial tiN coated Si 3N4 under dry machining conditions
(2008-12-01)
Due to their high hardness and wear resistance Si3N4 based ceramics are one of the most suitable cutting tool materials for machining hardened materials. Therefore, their high degree of brittleness usually leads to ...
