Today’s stringent design requirements and difficult-to-machine materials such as tough super alloys, ceramics, and composites, have made traditional machining processes costly and obsolete. As a result, manufacturers and machine design engineers are turning to advance machining processes. These machining processes utilizes electrical, chemical, and optimal sources of energy to bind, form and cut materials.
The principle of Occam’s razor loosely translates to “the simplest solution is often the best”. The author of Kinematic Geometry of Surface Machining utilizes this reductionist philosophy to provide a solution to the highly inefficient process of machining sculptured parts on multi-axis NC machines. He has developed a method to quickly calculate the necessary parameters, greatly reduce trial and error, and achieve efficient machining processes by using less input information, and in turn saving a great deal of time.
Machining processes produce finished products with a high degree of
accuracy and surface quality. Conventional machining utilizes cutting
tools that must be harder than the workpiece material. The use of
difficult-to-cut materials encouraged efforts that led to the introduction
of the nonconventional machining processes that are well-established
in modern manufacturing industries.
Improved manufacturing productivity, over the last 50 years, has occurred in the area of
machining through developments in the machining process, in machine tool technology
and in manufacturing management. The subject of this book is the machining process
itself, but placed in the wider context of manufacturing productivity. It is mainly concerned
with how mechanical and materials engineering science can be applied to understand the
process better and to support future improvements.
This chapter aims to provide basic backgrounds of different types of machining processes and highlights on an understanding of important parameters which affects machining of metals. • Mechanics of machining is introduced for the calculation of power used in metal machining operation • Finally defects occurring in the machining processes will be discussed with its solutions. Significant factors influencing economics of machining will also be included to give the optimum machining efficiency.
This book is concerned with the computational processing of 3D faces, with applications in human computer interaction. It is a discriplinary research area overlapping with computer vision, computer graphics, machine learning and HCI. Within the last 10 years, fast increase in performance of memory, display and processor
speed has allowed the expansion of Computer Graphics. It has now overcome Image
Processing in its achievement. In the 3D face field, the CG-generated faces are almost
indiscernible from real faces. Still it requires manual drawing for each image and artistic
