In machining complex dies, molds, aerospace andautomotive parts, or biomedical components, it iscrucial to minimize the cycle time, which reducescosts, while preserving the quality and toleranceintegrity of the part being produced. To meet thedemands for high quality finishes and low productioncosts in machining parts with complex geometry,computer numerical control (CNC) machine tools mustbe equipped with spline interpolation, feedratemodulation, and feedrate optimization capabilities.This books presents the development of noveltrajectory generation algorithms for Non UniformRational B-Spline (NURBS) toolpaths that can beimplemented on new low-cost CNC's, as well as, inconjunction with existing CNC's. The methods,presented here, generate near-optimal feed profilesthat have shorter cycle times, approximately 13-26%faster than the feed profiles obtained using theworst-case curvature approach, which is widely usedin industrial CNC interpolators. These methods arepractical and useful to professional in productionand manufacturing and to students, who are interestedin industrial robotics and control systems design.

Since launching the first textbook rental site in 2006, BookRenter has never wavered from our mission to make education more affordable for all students. Every day, we focus on delivering students the best prices, the most flexible options, and the best service on earth. On March 13, 2012 BookRenter.com, Inc. formally changed its name to Rafter, Inc. We are still the same company and the same people, only our corporate name has changed.
