Abstract: Grinding is one of the most difficult processes in machining operations. Normally, the flood coolant method was used as a cooling agent in the grinding process. The most common defects using flood coolant are higher grinding friction, higher heat generation, and thermal damage. Therefore, the minimum quality lubricant (MQL) was introduced to minimize the defects. The main objective of this project is to compare the performance of MQL and flood coolant techniques in terms of grinding temperature, grinding force and specific energy. Three levels of cutting speeds, three levels of feed rate and depth of cut are adopted in the evaluation. The experiments were conducted on a thin plate of mild steel AISI 1020. The result shows that the MQL technique was effectively supplied to the grinding contact zone. This research revealed that the MQL technique exhibited an advantages on the surface temperature compared to the flood coolant.

Abstract: This paper is focused on the application of acoustic emission (AE) based monitoring systems to grinding processes. To develop the AE signal model for the process monitoring, a comparison between the AE and power signals is presented. The AE model is developed according to a traditional grinding force model. Based on the developed model, experiment indicates the AE signal is similar to the power of spindle and verifies the proposed AE model can be used to predict the AE root meam square (RMS) signal for monitoring the grinding process.

Abstract: There are few water-based fluids, on the market, designed specifically for grinding and abrasive machining processes. Fluid manufacturers, caught up in serving the “non-cutting” functions, have neglected the prime reasons for using a grinding fluid. This paper begins to assess water-based fluid chemistries and observe the cause and effect relationship with respect to grinding power and wheel life. The end result will be not only be a next generation grinding fluid, but also a better understanding of the role of the grinding fluid in a grinding or abrasive machining operation.
