Choosing a CAD/CAM/CAE textbook is tricky: you need one that explains the theory without ignoring how parts actually get machined. The challenge is finding a solid reference that doesn't cost a fortune. That's exactly why the used trade paperback 'Principles of CAD/CAM/CAE' is worth a close look.
Quick verdict
If you're looking for a low-cost, serious introduction to the ideas that connect computer-aided design, manufacturing, and engineering analysis, this book belongs on your shortlist. At USD 8.88, it gives you a substantial trade paperback by Kunwoo Lee, a recognized author in the field. The listing describes the copy as Very Good, which means you're likely getting a readable, intact book rather than a beat-up reference. The price alone makes it an easy yes for students or hobbyists who want broad coverage without a big commitment.
Who it suits
This title fits anyone starting out in machining and manufacturing who wants to understand how CAD models become machined parts. It also suits self-learners who prefer a structured, textbook-style approach over scattered online tutorials. If you are studying mechanical engineering, manufacturing technology, or CNC-related courses, this book gives you the conceptual backbone you need before you touch a machine. At this price, it also makes sense for professionals who want a desk copy to refresh their memory on CAD/CAM/CAE fundamentals.
What stands out from the listed details
The book is a trade paperback with an ISBN of 9780201380361, so you can verify you're getting the exact edition you expect before buying. It has a substantial feel: 1.4 inches thick and weighing 35.5 ounces, which suggests a substantial reference rather than a thin pamphlet. The author, Kunwoo Lee, is named on the listing, and the title itself covers the full CAD/CAM/CAE spectrum. For the price, the depth of material per dollar is hard to beat.
Principles of CAD/CAM/CAE

The listing confirms you're buying a Very Good copy of this trade paperback. That means the pages should be intact and readable, though the cover may show normal wear. One important note: the images shown are stock photos, so the cover you receive might look different from the picture. The real value here is the content, not the packaging, so that's a fair trade-off at USD 8.88.
Meaningful trade-offs
Because this is a used copy, you won't get the pristine condition of a new book. The listing explicitly warns that the image is a stock photo, so don't expect an exact match for the cover. There is no mention of supplementary online resources, so you may need to rely on the printed material alone. Also, if you are looking for a step-by-step software tutorial for a specific CAD program, this book is likely more conceptual and broad; check the table of contents if you need something more hands-on.
Another point to consider: the book covers CAD, CAM, and CAE together, which is great for a foundation but not for deep, specialized instruction in any one area. If you already know the basics and need advanced machining strategies, you may need a more targeted resource. But for a learner who wants one affordable book that ties the whole digital manufacturing workflow together, this is a strong pick.
Bottom line
At USD 8.88, 'Principles of CAD/CAM/CAE' delivers a lot of useful engineering knowledge for very little money. The Very Good condition and detailed listing make it a safe buy if you set your expectations about the cover. Whether you are a student building your library or a curious maker exploring how CAD, CAM, and CAE fit into machining, this used paperback is a practical, low-risk way to get grounded in the fundamentals.
