This book introduces Autodesk Inventor® 6 and shows how to use Inventor to create and document designs. The content of the book goes beyond the material normally presented in an engineering drawing text associated with CAD software to include an introduction to designing simple mechanisms. The design portion of the book culminates with 10 design projects that serve as practical applications for all the material in the book.
All topics are presented using a step-by-step format so that the reader can work directly from the text to the screen. The book contains many sample problems that demonstrate the subject being discussed. Each chapter contains a variety of exercise problems that serve to reinforce the material just presented and allow the reader to practice the techniques described.
Chapters 1 and 2 present 2D sketching commands then show how to use the Extrude command to create simple models of uniform thickness.
Chapter 3 demonstrates the commands needed to create 3D models including the Shell, Rib, Split, Loft, Sweep, and Coil commands. Work points, work axes, and work planes are explained and demonstrated.
Chapter 4 shows how to create orthographic views from given 3D models. The creation of isometric views, sectional views, and auxiliary views is also covered.
Chapter 5 shows how to create assembly drawings using both the bottom-up and top-down processes. There is an extensive example of how to create an animated assembly, that is, a drawing that moves on screen. Drawing documentation, including presentation drawings, exploded assembly drawings, and parts lists, is also included.
Chapter 6 covers threads and fasteners. Drawing conventions and callouts are defined for both inch and metric threads. The chapter shows how to calculate thread lengths and how to choose the appropriate fastener from the Standard Parts library. Nuts, washers, setscrews, and rivets are also included.
Chapter 7 shows how to apply dimensions to drawings. Both the ANSI and ISO standards are demonstrated. Different styles of dimensioning, including ordinate and baseline, are covered as well as Inventor's Hole Table command.
Chapter 8 is an extensive discussion of tolerancing, including geometric tolerancing. The chapter first shows how to calculate appropriate tolerances, then shows how to use Autodesk Inventor to apply the tolerances to drawings. The chapter also includes several design problems that demonstrate how to calculate and apply positional tolerances to both fixed and floating conditions.
Chapter 9 presents bearings and shafts. The chapter shows how to calculate clearances for shafts and bearings and how to select bearings from manufacturers' catalogs and from the Web. Shear and bending diagrams are introduced (algebra only), and the results of the diagrams are used to calculate minimum shaft diameters and critical speeds. The chapter then demonstrates how to apply the results to selecting and supporting a shaft in bearings.
Chapter 10 introduces gears. Gear ratios, gear trains, the Lewis equation, and forces in gears are covered. Center distances and backlash are included as part of an explanation of how to design gear boxes. Examples are given demonstrating how to select gears from manufacturers' catalogs and from the Web. The chapter also shows how to animate Autodesk Inventor gear drawings so that the gears rotate on the screen.
Chapter 11 presents cams, springs, and keys. The chapter shows how to create a displacement diagram and then how to convert the displacement diagram information into a cam profile. The chapter shows how to design a spring, how to select an appropriate spring from the Web, and how to draw a spring. Various type of keys are presented along with their tolerance requirements. The chapter ends with a demonstration of cam animation.
Chapter 12 introduces sheet metal drawing and weldments. The chapter discusses the various sheet metal commands and shows how to create sheet metal drawings. The chapter also shows how to redesign existing parts into weldments. Only fillet welds are presented.
Chapter 13 demonstrates the design process, including how to manage the process. Concept sketches, evaluation matrices, team calendars, responsibility charts, and Gantt charts are presented using a design problem. The design problem starts with a problem statement and ends with a drawing of one possible solution.
Chapter 14 presents 10 design projects. The idea is for students to apply what they have learned in the previous chapters. The projects require students first to design a solution to the problem, then build and test a prototype, then document the solution using engineering drawings. Each of the projects is rated as to difficulty.
Thanks to the editors, Debbie Yarnell, Michele Churma, and Judy Casillo, and thanks to my family and especially to Cheryl.
