Evaluation of Cooling Potential and Tool Life in Turning

When cutting both compacted graphite iron (CGI) and titanium, tool wear was most effectively controlled using the scCO 2-based MWF compared with the other MWFs. Analysis in this paper suggests that the performance benefit imparted by rapidly expanding scCO 2 appears to be related to both the cooling potential and penetration of the sprays into the cutting zone.

Minimum Quantity Lubrication (MQL) in Automotive

This paper summarizes the advancements and challenges of minimum quantity lubrication (MQL) technology in automotive powertrain machining from both industrial and academic perspectives. MQL refers to applying a small amount of cutting fluid in the form of mist to the cutting zone rather than flooding the workpiece. Elimination of coolant systems creates significant saving from energy and

Impact of Supercritical Carbon Dioxide Metalworking Fluids

In end milling of compacted graphite iron (CGI) with uncoated carbide inserts, scCO 2 reduced tool wear by up to 50% when compared with the currently used metalworking fluid. These results are consistent with those from other applications that show scCO2-based metalworking fluids have the potential to reduce tool wear and cutting forces when compared with commonly used water-based

The mechanical and physical properties of Compacted

The mechanical and physical properties of compacted graphite iron (CGI) have been studied. While it is known that CGI provides at least 70% higher tensile strength, 35% higher elastic modulus and 80% higher fatigue limits than conventional grey cast iron, the objective of this paper was to determine how the properties change with varying nodularity (graphite shape) and pearlite content
