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, φd_1, φd_2, φd_3, φd_4, φd_5, etc. . The deep hole φd_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 φd_2 and the hole φd_5 and the positional accuracy requirements of the end face A of the hole φd_5 with respect to the axis φd_2
Outdoor Garden Light is typically used to illuminate areas such as gardens, lawns, pathways, and courtyards. They can be pole-mounted, wall-mounted, or ground-mounted and typically use LED or other energy-efficient bulbs to provide efficient lighting. Outdoor Garden Lights can also be equipped with sensors to automatically turn on or off when detecting people or animals, saving energy and increasing safety.
