| Abstract: | The problem of calculating the position of the cutter during three\|coordinate NC machining and programming is discussed. The formula of calculating the coordinate of the sphere\|shaped cutter's track of center at the machined hood face is analyzed.The reason and the compensating method of the machining error caused by using the sphere\|shaped cutter during machining are discussed. The formulas of the step and machining error are also given. |
