Unformatted text preview: a) Redesign the part for casting; if machining is to be done on any surface, a 0.1 in allowance should be added. Make a properly dimensioned, full-scale drawing of the cast part (in actual production, you would also have to find permissible radii and tolerances; for the assignment, simply indicate where the radii would be needed). Mark the machined outline in broken lines. b) Now choose an appropriate casting process assuming 100 parts are made every month. Show in a drawing how the part will be oriented in the mold and where cores should be placed if needed. c) Make a sketch of the pattern needed to build the mold. Assume a shrinkage factor 3%.
