CNC Machining Features

Type	Description	Example of visual representation
MTKBase_Boss	A boss is a protrusion or raised area on a workpiece that is created by removing material around it using a milling cutter. The boss feature can be used for various purposes such as providing a location for fasteners, creating a bearing surface, or serving as a mounting point for other components.
Machining_Pocket	A pocket is a feature obtained by milling the material inside an arbitrarily closed boundary on a flat surface of a workpiece removed to a fixed depth.
Machining_Hole	Hole is a cylindrical feature that can be made by cutting from the workpiece by a rotating cutting tool. The hole can be either a through hole or a blind hole. A through hole is a complete hole that you can see on both sides of the object, while a blind hole is only drilled, milled or reamed to get a specific depth. The blind hole can have a flat bottom or pointed end due to the ending point of the tool. Also, holes can be made at the edge of the material – partial holes, in this case only part of the hole is in the material.
Machining_Countersink	A conical hole cut into a manufactured object, or the cutter used to cut such a hole. A common use is to allow the head of a countersunk bolt, screw or rivet, when placed in the hole, to sit flush with or below the surface of the surrounding material.
Machining_Face or Machining_TurningFace	A face is a feature produced by a milling or turning operation. The face type is associated with the process in which the face was machined.
