Burr size point angle

The multiple regression analysis was performed for constructing the RSM-based burr size mathematical models. In the present investigation, the second order burr height and burr thickness mathematical models have been developed in terms of four process parameters, namely, cutting speed (v) feed rate (/), drill diameter (d) and point angle (. The nonlinear second order response surface equation is given by ... [Pg.270]

Interaction effect of drill diameter and point angle on burr size (v = 12m/min and f = 0.08mm/rev)... [Pg.280]

From the optimisation results, it is observed that the combination of optimal feed and point angle has played a key role in reducing the burr size for every drill diameter specified in the range 16-2 8mm. However, the different combinations of optimal feed and point angle are required for minimising the burr size. It is also revealed that, with the increase in drill diameter, simultaneous increase in feed and... [Pg.287]

The different combinations of feed and point angle are required to minimise the burr size for different drill diameter values specified in the range 16-28mm. [Pg.289]

With the increase in drill diameter, simultaneous increase in feed and point angle is desirable for controlling the burr size. [Pg.289]
