The purpose of this book is to explain the Fanuc turning canned cycles through a new didactic concept. In different manuals it is easy to find contrasting descriptions regarding the Fanuc turning canned cycles. Some manuals present the G74 function as an axial drilling cycle and others present it as a grooving cycle along the Z-axis. The G75 function is also described in some texts as a radial grooving cycle, while in others it is defined as a radial drilling cycle. It should be added that the G75 function is also able to perform a facing cut with chip breaking. The book aims to explain the Fanuc turning cycles in a definite way by adopting a new didactic method that is not limited to the simple description of cycle parameters, but includes all the machining operations that each cycle is able to perform.
