Abstract: A forming method of a processing curve in a stamping process is provided. The method includes the following steps. A plurality of processing curves are established, and an optimization target is set for the processing curves according to material characteristics of a workpiece, process requirements and a finished product CAD file. At least two of the processing curves are selected and superimposed to form a basic forming curve, wherein each subsection of the basic forming curve corresponds to a selected processing curve. Whether the selected processing curve in each subsection of the basic forming curve matches the optimization target is determined.

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 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.
