Abstract: A sheet metal hemming device is provided. The sheet metal hemming device includes a frame and a rolling wheel, a bearing wheel, a first rotating shaft, a second rotating shaft, a sliding block, an arc-shaped guide rail and a driver which are disposed on the frame. The rolling wheel is disposed on the first rotating shaft, the bearing wheel is disposed on the second rotating shaft, and an angle is formed between the rolling wheel and the bearing wheel. The sliding block is slidable relative to the arc-shaped guide rail and is connected to the rolling wheel via the first rotating shaft. The driver is connected to the sliding block for driving the sliding block to slide along the arc-shaped guide rail to adjust the angle between the rolling wheel and the bearing wheel.

Abstract: A grinding and polishing simulation method, a grinding and polishing simulation system and a grinding and polishing process transferring method. The grinding and polishing simulation method includes the following steps. A sensing information of a grinding and polishing apparatus when grinding or polishing a workpiece is obtained. A plurality of model parameters is identified according to the sensing information. At least one quality parameter is calculated according to a machining path, a plurality of process parameters and the plurality of model parameters.
