Machine Tools: Numerical Control Perspective
Pieces of bone or hard rock with pure silica were the earlier forms of cutting tools used by the mankind. However, mankind searched for better tool materials with the deficiencies of these materials. With the search for better materials, the better cutting methods were also explored. This process of search and exploration of new materials and methods is continuous and is done primarily when the existing methods are not efficient. The present chapter is an introduction to machine tools with discussion on material removal techniques, size and form, principle of operation with focus on kinematic behavior and surface texture.
