WebApr 30, 2024 · Primarily due to shear stain, the thickness of the chip increases as compared to that exists before shearing. This chip thickness becomes larger than uncut chip thickness, particularly for conventional macro scale machining. The ratio between the chip thickness (a 2) to the uncut chip thickness (a 1) is termed as chip reduction … WebMay 1, 2024 · Solution: The ratio between the uncut chip thickness (a 1) to the chip thickness (a 2) is termed as cutting ratio (r cu).Owing to lamellar shearing and positive strain, the chip thickness increases as compared to the same for uncut chip. Thus cutting ratio is smaller tan 1, especially for conventional macro scale cutting. WebChip thickness or grain penetration depth is an often-used measure of the amount of material removed by each abrasive grain. Hence, the acting mechanical load (and to … how gps works wikipedia
