The is the second edition of our series on Mastercam for SolidWorks. With lots of additions and thorough review, we present a book to help professionals as well as learners in creating some of the most complex NC toolpaths. The book follows a step by step methodology. In this book, we have tried to give real-world examples with real challenges in designing. We have tried to reduce the gap between university use of Mastercam and industrial use of Mastercam. In this edition of book, we have included many new topics of Mastercam 2017 for SolidWorks like Stock management, Chuck & Tailstock control by NC, Feature Based Toolpaths, Surface Roughing Operations, Surface Finishing Operations, 3D High Speed Toolpaths, Toolpath Trimming and Nesting, and so on. The book covers almost all the information required by a learner to master Mastercam for SolidWorks. The book starts with basics of machining and ends at advanced topics like 3D High Speed Machining Toolpaths. Some of the salient features of this book are : Every new topic of this book starts with the explanation of the basic concepts. In this way, the user becomes capable of relating the things with real world. Every chapter starts with a list of topics being covered in that chapter.
