Machinability of compacted graphite iron (CGI) and flake graphite iron (FGI) with coated carbide

International Journal of Machining and Machinability of Materials, 2013
Compacted graphite iron (CGI) has an important role in manufacturing of new generation engines. Better strength of CGI, as compared to flake graphite iron (FGI), allows CGI engine to perform at higher peak pressure, higher fuel efficiency and lower emission rate. However, the machinability of CGI is as poor as compared to FGI.

The influence of induction hardening on the impact wear resistance of compacted graphite iron (CGI)

Wear, 2011
The aim of this work was to study the impact wear resistance of untreated and induction hardened compacted graphite iron (CGI). Testing was carried out on a bespoke impact wear test rig to look at the effect of the material properties, before and after hardening, on the level of wear.

Milling Forces of Compacted Graphite Iron (CGI) and Gray Iron (GI)

Materials Science Forum, 2014
Compacted graphite iron (CGI) has excellent comprehensive performance of strength, hardness, abrasion resistance, shock absorption and thermal conductivity as an ideal material for making engine parts. The material performance of CGI is compared with that of gray iron (GI) and spheroidal graphite Iron (SGI). Some research shows that the strong adhesion

Modulation-assisted high speed machining of compacted graphite iron (CGI)

Journal of Manufacturing Processes, 2013
Abstract The application of controlled, low-frequency modulation (∼100 Hz) superimposed onto the cutting process in the feed-direction – modulation-assisted machining (MAM) – is shown to be quite effective in reducing the wear of cubic boron nitride (CBN) tools when machining compacted graphite iron (CGI) at high machining speeds (>500 m/min).

Investigation of microstructure and material properties for 18 different graphitic cast iron model materials with focus on Compacted Graphite Iron (CGI)

International Journal of Microstructure and Materials Properties, 2013
The higher mechanical strength of Compacted Graphite Iron (CGI) than Flake Graphite Iron (FGI) makes it very useful material for several commercial components. The knowledge of microstructure and hence the mechanical properties and machinability is very important for the CGI to used efficiently in manufacturing.

Evaluation of Hard Coating Performance in Drilling Compacted Graphite Iron (CGI)

Journal of Materials Engineering and Performance, 2013
The aim of this investigation was to compare the performance of the following commercial coatings system, TiAlN/TiN, AlCrN, and TiSiN/AlCrN, deposited in cemented carbide tools in drilling compact graphite iron (CGI). The drilling tests were conducted adopting two cutting speeds: 80 or 150 m/min.

Enhancing Tool Life in High-Speed Machining of Compacted Graphite Iron (CGI) Using Controlled Modulation

Tribology Letters, 2012
The application of controlled, low-frequency modulation superimposed onto the cutting process—modulation-assisted machining (MAM)—is shown to be quite effective in reducing the wear of cubic boron nitride (CBN) tools when machining compacted graphite iron (CGI) at high machining speeds (>500 m/min).

The Study of Mechanical Properties of Degraded Compacted Graphite Iron(CGI) Under 873~1273 K

Journal of the Korean Society for Nondestructive Testing, 2013
Compacted graphite iron(CGI), also known as vermicular graphite iron, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron. Recently compacted graphite iron has been used for diesel engine blocks.
