Most machines are built from two kinds of parts: standard catalog components like bearings, gears, linear rails, and fasteners, and custom parts designed and manufactured around them. The skill in machine design, beyond the technical base, is knowing which is which, and knowing how to make the custom parts work with everything bought off the shelf.
This guide breaks down the full machine design process, from concept to manufactured assembly. It covers the buy/make framework, the stiffness, stress, and vibration fundamentals that govern every part, how to select materials, how to design custom geometry around standard bearings, shafts, and gears, the fits and tolerances that make parts actually assemble, and the manufacturing and assembly choices that turn a design into a working machine.
What You Get With the Machine Design Guide
Get a practical, engineering-focused walkthrough of machine design decisions, from initial concept to finished assembly.
In this guide, you'll learn:
- How to apply a 5-question buy/make framework at each stage of the design process, from initial concept through production
- The stiffness, stress, and vibration equations that govern catalog and custom parts, including deflection, natural frequency, stress concentration, and fatigue
- Yield and tensile strength data for six materials used in machine frames, shafts, and housings, and how to choose between them
- What to standardize and what to design custom across the part types in nearly every machine: fasteners, bearings, shafts, gears, structural frames, and linear and rotary motion systems
- How to size fits and tolerances, from fastener thread engagement to ASME versus ISO GD&T defaults, so custom parts actually assemble with the standard components around them
- Design for Assembly principles that cut labor and error rates on the line
