21st Century Manufacturing
Prentice Hall, 2001 - 460 من الصفحات
Written in a conversational style, this book explores today's technologies and the future of manufacturing -- through details of the product design process, rapid prototyping, a survey of manufacturing techniques relevant to today's production of consumer electronics or electromechanical devices, and the field of Biotechnology. It gives readers a broader appreciation of the impact of manufacturing process and not just manufacturing per se. A overview of the broader issues includes: the time to market, development of a new product, launching products into the marketplace, quality control, and the impact of technology on the next generation of products. Chapter topics cover manufacturing analysis; product design, computer aided design, and solid modeling; solid freeform fabrication and rapid prototyping; semiconductor manufacturing; computer manufacturing; metal-products manufacturing; plastics-products manufacturing and system assembly; and biotechnology. For executive education courses, appealing to both engineering and business professionals.

Also , it is crucial to adjust the laser position with reflective " eyes " at the corners of the machine's stage . In fact , this check of laser posi- tion occurs just before each layer is done . 220.127.116.11 Step 3.
Note that the bottom of each SLA layer has to adhere to the previous layer , and so the topic of main interest is the " energy at depth z " of the laser . Lasers give much more energy ( i.e. , are able to cause more " polymerization by ...
The laser exposure's average energy density is then E ( average ) = Х Haverage te = 38.2 mJ / cm2 ( 4.6 ) The analysis now proceeds to calculate the polymerization ability from the laser's photon flux . It is necessary to use Planck's ...

This book provides a very basic overview of manufacturing processes. Unfortunately, it does not do a very good job of explaining the basic phenomena behind these processes. Wikipedia can do almost as good a job as this book. قراءة التقييم بأكمله
