WebSep 29, 2024 · When f z / r n = 0.1, the resultant forces of the carbide and self-manufactured PCD cutters are 1.11 N and 0.93 N, respectively. When f z / r n increases to 2, the corresponding resultant forces were 1.96 N and1.58 N, respectively. The force growth of the carbide cutter (0.65 N) was significantly higher than that of self-manufactured PCD … Webchip thickness after the cut (t 2) is always greater than the chip thickness before the cut (t 1 ), ∴ r is always < 1, i.e. the uncut chip thickness value is less than the chip thickness value. Assuming volume to be constant: t1b1L1 = t2b2L2 t 1 t 2 = L 2 L 1 ( ∵ b 1 = b 2) WebThe ratio of to to tc is called the chip thickness ratio (or simply the chip ratio) r. {r= to/tc}.
