Chip thickness ratio r is always
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 … 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}. The chip ratio is always less than one. WebThe above discussion leads to the result that t2>t1. The chip thickness ratio `r’ is given by: r = t1/t2. Since t2 always greater than t1, the value of chip thickness ratio `r’ is less than unity. The higher the value of `r’ the better is supposed to be the cutting action. The reverse of `r’ is known as chip reduction coefficient.
