Abstract: A part processing planning method includes the following steps. Firstly, a specific tolerance of a nominal size of a part is obtained. Then, a predetermined tolerance of each of processes is obtained. Then, using a process dimension chain establishing technique, at least one predetermined tolerance associated with the specification tolerance from the predetermined tolerances is obtained. Then, at least one predetermined tolerance associated with the specification tolerance is accumulated to obtain a size cumulative tolerance. Then, whether the size cumulative tolerance meets the specification tolerance is determined. Then, at least one predetermined tolerance associated with the specification tolerance is re-allocated when the cumulative tolerance does not meet the specification tolerance, such that the size cumulative tolerance is within the specification tolerance.

Abstract: A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.
