Chip thickness ratio derivation
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. WebThe chip thickness is an important consideration when deciding the feed per tooth, to ensure that the most productive table feed is employed. Average chip thickness, hm A …
