| Abstract: | The method of measuring cone angle on sine protractor is discussed,and the corresponding calculation formula is deduced.The deduced formula is compared to the formula given in the handbook.It is indicated that the formula given in the handbook has limitation.It is shown by a measurement example that using the deduced formula in calculation can give more accurate result when the bevel is bigger than 7°. |
