Chip thickness ratio r is always
WebThe chip thickness ratio 'r' in Orthogonal metal cutting operation is always: A. Greater than unity B. Equal to unity C. Less than unity D. Equal to depth of cut Please scroll down to see the correct answer and solution guide. Right Answer is: C SOLUTION Explanation: Chip thickness ratio / Cutting ratio (r): 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.
