A manufacturing engineer needs an estimate of the cutting force Fc to estimate the loss of accuracy of a machining process due to deflection. The material being machined is Inconal 600 with a BHN value of 100. The cutting speed was 250ft/min, the feed was 0.020 in./rev, and the depth of cut was 0.250 in. The chip from the process measured 0.080 in. thick. Estimate the cutting force Fc, assuming that Ft = Fc/2.
