Aligning Parts in An Assembly  \n12.1. INTRODUCTION TO ASSEMBLY  \nAssembly drawings show how the components of a design fit together dimensions and other details are usually omitted in assembly drawings to enhance clarity. Several styles of assembly drawings are commonly used. Sometimes the assembly drawing is just an isometric view of the assembled device. But an exploded isometric view is often helpful to show the individual parts are assembled, as shown in Figure 12.1 for a pizza cutter. In some cases, a sectioned assembly, or cut-away view, shows how complicated devices are assembled. A cutting plane passes through the assembly and part of the device is removed to show the interior of the assembly. Numbers or letters can be assigned to individual parts of the assembly on the drawing and keyed to a parts list.  \nFinally a part list, or bill of materials, must be included with a set of working drawings. The parts list includes the part name, identification number, material, number required in the assembly, and other information such as catalog number for standard parts.  \nFigure 12.1 Assembly drawing of pizza cutter (from [2])  \nAn assembly drawing shows all of the components of a design either assembled or in an exploded view. Many times assembly drawings include sections. Most dimensions new are omitted in assembly drawings. Individual parts are not dimensioned, but some dimensions of the assembled mechanism may be included. Hidden lines are seldom necessary in assembly drawings , although they can be used where they clarify the design. Leader lines attached to a ballooned letter or detail number, reference the parts of the assembly. The leader lines should not cross and nearby leader lines should be approximately parallel. Name r ather  \n1  \nPDF created with FinePrint pdfFactory Pro trial version [http://www.fineprint.com](http://www.fineprint.com)  \nthan number labels sometimes parts. The parts list may be on the assembly drawing; (usually on the right side or at the bottom) or it may be a separate sheet. The assembly drawing may also include machining or assembly information in the form of notes on the drawing.  \nOften assembly drawings include assembly sections. These are typically orthographic or pictorial section views of parts as put together in an assembly. Adjacent parts in assembly drawings are cross-hatched at different angles to make the separate parts clean. The assembly cross-section on the left side of Figure 12.2 shows the interior structure of tile pads of a pizza cutter and. The detail view in the upper right of Figure 12.2 shows the cross-section through the rivet to indicate how the parts are assembled. Usually standard parts such as fasteners, washers, springs, bearings, and gears are not cross-hatched.  \nIn this case the small rivet holding the blade onto the arms of the pizza cutter is too small to see in the orthographic views. The region of interest near the rivet is circled in the left-most projection of the pizza cutter, and a note directs the reader to a magnified detail view in the tipper right part of the drawing. The cross section of the rivet is clearly visible in this detail view.  \nFigure 12.2 Sectional drawing of pizza cutter (from [2])  \n12.2. ASSEMBLY DRAWING  \nWhen a machine is designed, such as a lathe, an assembly drawing is prepared to show the general arrangement of the machine. This drawing should show the finished product with all parts assembled in their correct relative positions. An assembly drawing may include overall dimensions and functional and fitting dimensions. An assembly drawing shows how each part of a design is put together. (Figure 12.3) If  \n2  \nPDF created with FinePrint pdfFactory Pro trial version [http://www.fineprint.com](http://www.fineprint.com)  \nthe design depicted is only part of the total assembly, it is referred to as a subassembly.
