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 ... Webchip reduction coefficient means more chip thickness, which means more efforts of forces or energy is required to accomplish the machining work. It is always desirable to reduce … WebCl – Chip Load. (Recommended by the tools supplier or from our Chip Load Calculator). Ae – Radial Depth of Cut. D – Cutter Effective Diameter.
