I am teaching "Design of Jigs, Fixtures and press tools". For Jig design I am referring "jig and Fixture design" by Edward G.Hoffman IV edition. In that, for joining two plates (design of Plate jig for Housing cover, Page No.165 fig.11-15), 4 cap screws & 3 dowel pins are used. In the same way, in page no. 195 fig.13-12, 2 cap screws & 2 dowel pins are used. Can you explain, how to select the size of cap screws & dowel pins.
Thanks in advance ilamathi
