The use of computers for engineering design, and in CNC for manufacturing, has dramatically changed the cam design and manufacturing process. Additionally, cam design and manufacturing have been affected by a significant number of fundamental research results published in recent years. This new edition offers changes which have been made throughout the book to update its information with the latest technology from the engineering literature and from the author's research and that of his students. Beginning at an introductory level and progressing to more advanced topics, this it provides all the information needed to properly design, model, analyze, specify, and manufacture cam-follower systems. It is truly a comprehensive resource that brings together up-to-date cam design technology, correct design and manufacturing procedures, and recent cam research results-all in one volume! Additionally, this unique book is accompanied by a 90-day trial demonstration copy of the Professional Version of Dynacam. Written by the author and used worldwide, this program solves the equations described in the book and allows in its fully licensed version the design, dynamic modeling, analysis, and generation of follower center, cam surface, and cutter coordinate data for any cam. It also defines conjugate cams for any application. It includes a completely rewritten and updated chapter on splines, along with a discussion of shape-preserving splines as currently used for automotive valve-train cams. It features added coverage of multi-degree of freedom models and of followers with deliberate impact events within the chapter on dynamic modeling. It covers Globoidal cams in several chapters. It provides a definitive solution to the torque compensation cam design problem.

Point Connett in Mattapoisett, Massachusetts, is a seaside community of 105 houses; most are year-round, and some are summer cottages. It is located on the western shore of Buzzards Bay, which is a large inlet that separates the mainland from Cape Cod to the east. The name Point Connett is from that of a Wampanoag Indian who, in the 1600s, took the anglicized name William Connett. Prior to King Philip's war (1675-1678), he owned much of the land in Rochester and Mattapoisett, including Point Connett, now named for him. Mattapoisett is a Wampanoag word that translates as "A Place of Rest." It has been, since its beginning, a lovely and friendly community. Several families trace their roots on "The Point" back to the beginning, and some third- and fourth-generation descendants still own homes here, peopled with fifth-generation children. The book, overall, is a collection of independent chapters, each written by members of different families about their personal experience of Point Connett. These have been collected and put together by the editor, and added to a Prologue that recounts the Point's early history as assembled from available sources. The collection of stories here very clearly and effectively demonstrates the character and activities of this lovely community by the sea and nicely captures the zeitgeist of Point Connett.

Drawing upon thirty-two years of school work (including classroom teaching, school administrator, principal, District Curricula Director responsible for change, and school psychologist), the principals of control theory/reality therapy and Dr William Deming's philosophy on quality management, this "how-to" text is for classroom management.
