Chip thickness equation
Web1-Describe in detail what the Merchant equation tells us, how the shear plane angle effect machining, show by drawing in cross-sectional view. (25p) 2-Describe and tell in detail with your own words the general relationship of tool wear versus cutting time given below, (25p) 3-Assume that for a given tool and workpiece combination, n = 0.5 and ... WebWhen chatter occurs, the vibration frequency h shown in Equation (4) is also called the chatter frequency. As mentioned above, the phase shifts between the cutting ripples occurring in the milling processes, except for phase angles equal to 0° and 180°, vary the chip thickness and are prone to induce the occurrence of chatter.
