2. As shown in Fig 4, silver plating on surface oF is required, and the plating depth is 0.2 - 0.3mm. The final dimension of OF is 9630.08 mm. Try to find the dimension A1 and its +0.1 tolerances in order to ensure the plating depth 0.20 mm indirectly and also draw the process dimension chain of the silver plating.(15 points) Fig 4 Dimensions of silver plating OF 2.
