Manufacturing and assembling plan: Based on our product design and the model we have made with UG, we made several plans to manufacture the product and take the one of which we thought to be the most reliable and simplest. As the product we are going to manufacture mainly include 3 parts: the pedestal which we call ‘box’, the brackets and the holder, we decided

to process each part separately and then assemble them For the box,we use the aluminum-plastic plate as the raw material. Cut off the components from the plate using the electric saw according to the size that has been calculated in the design part.Then connect them by strong adhesive and hot melt glue. The brackets purchased need to be reformed,the rotary hinges that connecting the bars are too large in their length,so we decided to replace them by the screws.We need the saw and the fitter machine to be the tools of processing. For the part that holding the mobile phone,we need to slot a groove which is going to be the chute of the prismatic joint that is adjustable for the purpose of expanding and folding the mechanism.Here we will need the lathe for drilling. After all of the procedures above,assemble the separated parts by the screws.

3.cutting grooves: We planned to slot the grooves using the vertical milling machine, however,we found it to be hard to press the board from both sides. Therefore we accomplish this task by sawing with the electric saw instead. Processing tools:electric saw,mill(锉刀)； Parameters:Width of the groove:4-5mm. Length:according to the graph paper. The boards need to slot the grooves: 12*8#2,12*6#1,180*15#4,180*35#4 According to the graph paper,label the cutting path on the boards,cut off the undesired part and take out the wastes,Mill the rough edges with the file.Expand the grooves to the appropriate width in which the screw could slide.Then mill and make the edges smooth.At last mill the closed angles into roundish to prevent the mechanism to get stuck at that
