Chip thickness ratio formula
WebA moderate removal rate of Q = 50 mm 3 /s over a 25-mm wide cut is quoted as Q′ = 2 mm 3 /s per mm width or 2 mm 2 /s equivalent to 0.186 in. 2 /min in British units. In HEDG, a possible removal rate as high as Q = 1200 mm 3 /s over a grinding width of 2 mm translates to Q′ = 600 mm 2 /s (or 55.8 in. 2 /min). WebEither the chip compression ratio has been used to measure the chip thickness during simulation (see e.g., [36,[51][52][53][54]) or the inclination angle of the conventional …
