The workpiece shown in Figure 1 is the main component of the crankshaft of a four-stroke motorcycle engine. Under normal circumstances, the variety of the crankshaft is different, the shape of the component parts is unchanged, and only some dimensions of the component are formed (see Figure 1), such as L_1, L_2, L_3, Ï†d_1, Ï†d_2, Ï†d_3, Ï†d_4, Ï†d_5, etc. . The deep hole Ï†d_1 of the workpiece is inconvenient to be processed by a conventional method on a drill press or a horizontal lathe. The dimensional accuracy of the axis Ï†d_2 and the hole Ï†d_5 and the positional accuracy requirements of the end face A of the hole Ï†d_5 with respect to the axis Ï†d_2
