WebBy definition, clearance angle is the angle of orientation of tool’s principal flank surface from the cutting velocity vector (Vc) and measured on some other plane. Sometime, instead of using cutting velocity vector (V c ), cutting plane (π C) is used in definition as cutting plane itself contains cutting velocity vector. WebIn geometry, a flat surface is also called a plane. Plane geometry deals in flat shapes that you can draw on a piece of paper, such as squares, circles, and triangles. A plane or flat figure has two dimensions: length and width. A solid or 3D shape is a shape that takes up space. The outer layer of a solid is called the surface of the solid.
