“…Shaw 24 In the literature, the effect of cutting speed was studied mainly using shaped abrasive grits in order to minimize the influence of grit shape alteration during scratching test 11,14,27 . The majority of the research show that lower cutting speed and depth of cut increase the proportion of ploughing and make cutting less efficient 16,27,28 . The influence of cutting speed may not be captured appropriately when the grit feature changes significantly due to grit wear and fracture on the cutting edges.…”

This paper presents an important investigation of material removal mechanism in grinding utilizing single grit scratch tests. The investigation helps people to understand the abrasive cutting behaviour when the abrasive cutting edge shape alters during single grit grinding. The results provide fundamental knowledge of the grinding material removal process which helps to improve grinding performance and quality. CBN grits of 40/50 mesh size were used to perform scratch tests on the alloy Inconel 718. The concepts of material pile up ratio and material removal strength were introduced to measure the material removal efficiency during grinding. It is found that pile up ratio decreases and material removal strength increases when the depth of cut increases, albeit the material removal mechanism is highly dependent on the abrasive grit cutting edge shape. The material removal mechanism along the scratch length shows different behaviours at the entrance and exit sides of the scratching passes. When a grit was moving along its scratch path, it pushed material forward resulting in high material accumulation at the exit side of the scratches. Consequently, cutting is more prominent at the entrance side of the scratch, whereas ploughing or pile-up is extremely high at the exit side of the scratches. The research finding provides crucial information for grinding process optimization.

“…Their investigation showed that a large number of grits on the surface of the wheel passing over the workpiece per second (around million or more per second), only very small fraction of the grits merely rub or plough into the workpiece ($ 3.8% for form and finish grinding and $1.8% for stock removal grinding) and even smaller fraction ($ 0.14% for form and finish grinding and $ 1.8% for stock removal grinding) of that participate in actual cutting. The majority of the researches shows that lower cutting speed and depth of cut increase the proportion of ploughing and make cutting less efficient [11,20,21].…”
