Chip thickness equation

WebThe general equation for the maximum undeformed chip thickness is [24]: (9.20) t max = E 1 E 2 0.548 4 v V t C n r d D Where E 1 and E 2 are the Young’s modulus of both the grinding wheel and the workpiece, respectively. WebThe relationship between chip thickness ratio (r) and the shear angle can be obtained from the Fig. 22.13 (a). This chip thickness ratio is defined as the ratio of the depth of cut (t) to the chip thickness (t c). It may be noted that in Fig. 22.13 (a), AF which is perpendicular to tool chip interface represents t c, i.e. chip thickness.
