Which of the following is a junction of side and end cutting edge in single point cutting tool?

Explanation

Explanation: Single point cutting tool Nose It is the intersection of side cutting edge and end cutting edge Heel It is the intersection of the flank and base of the tool Shank It is the main body of a tool Base It is the bottom part of the shank. It takes the tangential force of cutting Face: Face is the surface of the tool on which chip impinges when separated from work-piece Side Cutting Edge Angle: The angle between side cutting edge and side of the tool shank is called side cutting edge angle. It is also called lead angle or principle cutting angle. End Cutting Edge Angle: The angle between the end cutting edge and a line perpendicular to the shank of the tool is called end cutting edge angle. Side Relief Angle: The angle between the portion of the side flank immediately below the side cutting edge and the line perpendicular to the base of the tool measured at right angles to the side flank is known as side relief angle. It is the angle that prevents interference, as the tool enters the work material. End Relief Angle: End relief angle is the angle between the portion of the end flank immediately below the end cutting edge and the line perpendicular to the base of the tool, measured at right angles to end flank. It is the angle that allows the tool to cut without rubbing on the work-piece. Back Rake Angle: The angle between the face of the tool and a line parallel with the base of the tool, measured in a perpendicular plane through the side cutting edge is called back rake angle. It is the angle that measures the slope of the face of the tool from the nose toward the rear. If the slope is downward toward the nose, it is a negative back rake angle. And if the slope is downward from the nose, it is a positive back rake angle. If there is not any slope, the back rake angle is zero. Side Rake Angle: The angle between the face of the tool and a line parallel with the base of the tool, measured in a plane perpendicular to the base and side cutting edge is called the side rake angle. It is the angle that measures the slope of the tool face from cutting edge. If the slope is towards the cutting edge, it is a negative side rake angle. If the slope is away from the cutting edge, it is a positive side rake angle.
