Regenerative chatter Phenomenon in the Turning Process based on the alloy steels 1020, 1035 and 1045
(International Journal of ChemTech Research, 2018)
Regenerative vibration is a major drawback in machining processes reducing the
geometric accuracy and dynamic stability of the cutting system. Achieving a dynamically stable
cutting operation represents a significant ...
Experimental study of the cutting processes on the microstructure of an ASTM A36 steel
(Contemporary Engineering Sciences, 2018-06-25)
This article analyses the microstructure of ASTM-A36 steel both in its delivery
state and after various cutting processes. The material was cut with some methods
conventionally used in the metal-mechanical and construction ...
Incidence of the lean philosophy construction in the productivity and analysis of processes in internal finishes in masonry living quarters in the construction projects: case-residential complex Callejas-Cucuta-Colombia
(Contemporary Engineering Sciences, 2018-08-30)
The technical supervision in the construction projects is of special importance for
the correct execution of the activities, its objective is to reduce the errors that are
incurred when carrying out the processes inherent ...
Analysis and optimization for the process of glass tempering using autoclave
(Journal of Physics: Conference Series, 2018-12-07)
A mathematical analysis of the glass tempering process was carried out using an autoclave, varying the operating parameters of the system. It was found that the process time can be reduced by up to 3.23% by changing the ...
Experimental study of the effect of cutting processes on the roughness of ASTM A36 steel
(Contemporary Engineering Sciences, 2018-06-06)
This article analyses the roughness of ASTM-A36 steel both in its delivery state
and after various cutting processes. The material was cut with different methods
conventionally used in the metal-mechanic and construction ...
Clay surface characteristics using atomic force microscopyCaracterísticas superficiales de la arcilla utilizando microscopía de fuerza atómica
(Revista Facultad de Ingeniería Universidad de Antioquia, 2018-06-07)
The first component for the manufacture of masonry products used in construction is clay, which provides the plasticity that facilitates the molding and handling of the product. The second component is the feldspar in form ...
Substitution of natural stony material aggregates in conventional 17.5 mpa non-structural concrete mixtures by means of percentage addition of hospital solid waste
(Contemporary Engineering Sciences, 2018-11-29)
An experimental character research was carried out. A conventional concrete
mixture was made with the mechanical resistance to compression of 17.5 Mpa.
The materials used in the concrete mixture were analyzed and selected ...
Sustainability under research in green energy: A bibliometric study
(International Journal of ChemTech Research, 2018)
The reduction of the amount of pollution and toxicity by the manufacture of
products has been a topic widely investigated by many international organizations, looking for
an answer that help humanity to minimize the ...
Articulation of environmental management in projects of non-conventional energy sources in the Caribbean Colombian region
(Journal of Physics: Conference Series, 2018-12-07)
This work addresses an inclusion methodology based on criteria for the implementation of non-conventional energy sources and critical environmental factors for the licensing of the same, which is applied to the case study ...
Behaviour of the contact trace in a cam-follower system when the displacement law has been designed using bézier curves
(Contemporary Engineering Sciences, 2018-11-06)
The study shows the distribution of the contact trace in a cam - follower
mechanism in which the Bézier curves of degrees 5, 7 and 9 have been used for
the design of displacement of the follower. The equations that ...
