Antioxidants: The challenge for additive manufacturing
By Dr. Robert Gresham | TLT Contributing Editor
Today, nearly all lubricant formulations contain some kind of antioxidant in some concentration. This is because oxidation is the primary cause of oil degradation. Thus improving oxidation resistance is critical to improving lubricant stability and the operational life of the lubricant, in turn allowing for extended oil drain intervals. Extending the drain intervals save direct maintenance costs, reduces waste treatment cost and potential exposure to the environment and reduces overall cost and consumption from well head to the waste treatment plant.

The body mechanical
By Dr. Nancy McGuire | TLT Contributing Editor
Back in the 1970s, the Bionic Woman’s medical implants gave her superhuman powers. People in the real world also had artificial implants, but these parts only restored some semblance of normal function to aging or injured bodies. Today medical implants still mainly repair and replace parts rather than enhance performance, but they come into play at the much earlier stage of damage, and their users typically enjoy a more active lifestyle than was previously possible.

Experimental Investigation on the Compatibility of Nanoparticles with Vegetable Oils for Nanofluid Minimum Quantity Lubrication Machining
By Songmei Yuan, Xuebo Hou, Li Wang & Bochuan Chen
Several health and environmental related issues caused by the application of traditional cutting fluids in machining can be solved by implementing eco-friendly technologies such as minimum quantity lubrication (MQL). Moreover, nanofluid MQL has been proposed to enhance the cooling/lubricating properties of pure MQL and displays significantly good results for machinability. However, the mechanism on compatibility of nanoparticles with cutting fluids has not been explored. In this study, nanoparticles with different hardness and vegetable oils with different viscosity were selected for nanofluids preparation. The end milling experiments were carried out on 7050 material by applying MQL with particularly prepared nanofluids. The cutting force and surface roughness were measured corresponding to the machining performance. The compatibility of hardness of nanoparticles with viscosity of base fluids has been evaluated, and the mechanism has been analyzed by new-designed tribology tests. Results show that canola oil-based diamond nanofluids MQL exhibit the lowest cutting force and natural77 oil-based diamond nanofluids perform the lowest surface roughness with reduction of 10.71 and 14.92%, respectively, compared to dry machining condition.

Condition Monitoring of Metalworking Fluids Webinar Presented by Dr. Neil Canter
Live webinar taking place Wednesday, August 22nd, 2018 at 12pm Central Time
Maintaining the optimum performance of a metalworking fluid over an extended operating period is quite challenging. The key operating parameters of an in-use metalworking fluid need to be monitored on a periodic basis to ensure that optimum performance is maintained. This webinar will discuss some of the important monitoring tests that need to be run to evaluate the condition of a metalworking fluid over time. As a conclusion, a brief discussion will be held about how the data can be applied to a metalworking fluid system. Click here to register.
