                             Machined Part



                             In earlier conversations with manufacturing, a
                             decision was 1nade that the part would be

                             machined.

                             Your material supplier stocks raw material in rod,
                             sheet, plate, angle and block forms.

                             You decide to start with a standard plate form.
                             A standard plate form wi II  save time and
                                                                                                      Block, Anrje and Rod Stock
                             money.

                             Select the best profile for the extrusion. The
                             best profile is a simple 20 rectangle.


                             The boss and square internal cuts are very
                             costly to 1nanufacture from machined bar                                                       Boss is costly lo<

                             stock.

                             As a designer, review your 111anufacturing

                             options.

                             Utilize standard material thickness and hole
                             sizes in the PLATE design. Utilize standard
                             stock in the ROD design.

                             Utilize slot cuts in the GUIDE design.

                             Machined parts require dimensions to
                             detem1ine the overall size and shape. Datum
                             planes determine the location of referenced

                             dimensions. Add geometric relations and
                             dimensions to full y define the geometry

                             Understanding reference planes and views is i1nportant as you design machined parts.
                             Before you create the PLATE, review the next topic on Reference Planes and

                             Orthographic Projection.
