Описание: Are you utilizing 5-axis machining? Could your shop benefit from the efficiency and power that 5-axis machining offers? The majority of people not embracing this technology lack a true understanding of 5-axis practices. There are many common misconceptions on the subject, and the intent of this book is to demystify 5-axis machining and bring it within the reach of anyone interested in using the technology to its full potential. The information presented in this book was gathered during 30 years of hands-on experience in the metal-working manufacturing industry — bridging countries, continents, and multiple languages (both human and G-code.) The author worked in Hungary, Germany, Canada, and the USA, specializing in multiaxis solutions. He spent many years setting up, programming, and repairing CNC equipment, and has used a number of different CAD/CAM systems. He has worked as a self-employed multiaxis consultant, as well as directly for CGTech (the makers of VERICUT®) and CNC Software Inc. (the makers of Mastercam®.)
The author has instructed countless multiaxis training classes over the past decade. These classes covered topics such as operating CNC equipment, programming CNC equipment, both manually and with CAD/CAM systems, and building virtual machines with different verification systems. Through the years, the author has met many professionals around the world and has come to a realization that they all have the same questions, misconceptions, and concerns, when it comes to 5-axis machining. The need for unbiased information on the subject became apparent.
Up to this point, the best way to get information on 5-axis machining was to talk to peers in the industry, in the hope that they would share what they had learned. Visiting industrial trade shows and talking to machine tool and CAD/CAM vendors are other options — except that these people all give their individual points of view and will promote their own machine or solution. Everybody claims to have the best mouse-trap, and it is left to the individual to choose the right one.
This book is not a training manual for any particular machine or CAD/CAM system. Rather, it is an overview of multiaxis machine types and the common control methods that CAD/CAM systems use to drive the machines. The book will guide you through this realm, from basic to complex concepts, and will provide information to help you choose the right tools, including the machine, work-holding method, CAD/CAM system, and machine simulation package that will best suit your specific application. The book contains numerous illustrations to help you to precisely implement these tools.
