Jay has written a new set of lesson plans for Part Wizard 3 and the ShopBot. Download them from http://www.shopbottools.com/forteachers.htm. (Note that his earlier files using Vector CAD/CAM are still available. Be sure to download the current version called Weise Lesson Plans.)
Incorporate them into your own class or use them to show how a CNC router can be used in a school setting.
