Using the relationship between the chip thickness and cutting variables and Merchant's equation to determine the percentage increase in chip thickness when the friction is doubled.
WebApr 25, 2024 · Since rake angle can be positive, zero or negative, so algebraic sum should be considered. The chip reduction coefficient (ζ) is the ratio between chip thickness (a 2) to the uncut chip thickness (a 1). Since a 2 > a 1, so ζ = (a 2 /a 1) > 1. Chip reduction coefficient is inverse to the chip thickness ration (r c). Given values in the ...
