Abstract: A hemming path planning method and a hemming system are provided. The hemming path planning method includes the following steps. An initial contour data of a target is scanned to obtain. A first segment of the hemming path is planned according to the initial contour data. The first segment corresponds to a first bending angle. A second segment of the hemming path is planned according to the initial contour data and an expected springback amount related to the first bending angle. The second segment corresponds to a second bending angle. The first segment and the second segment are combined to obtain a continuous hemming path.

Abstract: A braiding path generating method includes the following steps. Firstly, a mandrel model is received. Then, an outer diameter of the mandrel model is obtained. Then, a target braiding angle is obtained according to a target coverage rate and the outer diameter of the mandrel model. Then, a braiding simulation path is generated according to the target braiding angle.

Abstract: A wire tension control device including a bobbin and a magnetic moment generator is provided. The bobbin is configured to provide a wire. The magnetic moment generator includes a stator and a rotor relatively rotatable with respect to the stator. The rotor is connected to the bobbin. When the bobbin drives the rotor to rotate, the magnetic moment generator generates a tension on the wire.

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.
