The latest information indicates that the United States now spends in excess of $150 billion annually to perform its metal removal tasks using conventional machining technology. That estimate is increased from $115 billion 5 years ago. It becomes clear that metal removal technology is a very important candidate for rigorous investigation looking toward improvement of productivity within the manufacturing system. To aid in that endeavor, an extensive program of research has developed within the industrial community with the express purpose of establish ing a new scientific and applied base that will provide principles upon which new manufacturing decisions can be made. One of the metal removal techniques that has the potential for great economic advantages is high-rate metal removal with related tech nologies. This text is concerned with the field of grinding as a subset of the general field of high-rate metal removal. Related processes (not cov ered in this text) include such topics as turning, drilling, and milling. In the final evaluation, the correct decision in the determination of a grind ing process must necessarily include an understanding of the other methods of metal removal. The term grinding, as used herein, includes polishing, buffing, lapping, and honing as well as conventional defini tion: " . . . removing either metallic or other materials by the use of a solid grinding wheel."

Living the Mysteries is a daily devotional--and more--for the period from Easter to Pentecost. Each day features: a brief meditation; a short passage from that day's Mass readings; a reflection on the reading adapted from the writings of the Fathers of the Church; a particular focusing on a relevant point of the mystical or moral life; and a plan with practical applications for everyday prayer and living. This is a thoughtful, practical, and sure-to-be appreciated gift for any new Catholic! (And a great choice for longtime Catholics, too.)

The word peregrinacion permeates Spanish, Italian, and Portuguese literature, and can be described as wandering, alienation, and exile, combined with pious devotion. Complementing the work of Antonio Vilanova, Juergen Hahn's study of peregrinacion focuses on Spanish literature of the Golden Age.
