Nose radius is an important parameter in machining processes. It refers to the radius of the cutting edge of a tool. The following statement is true about nose radius:
Large nose radius results in chatter
Chatter is a phenomenon in machining where the tool vibrates excessively, causing surface irregularities and poor surface finish. Large nose radius can lead to chatter due to the following reasons:
• Reduced stiffness: Large nose radius reduces the stiffness of the cutting tool, making it more prone to vibrations. This is because a larger radius means less material in contact with the workpiece, resulting in reduced damping.
• Increased cutting forces: Large nose radius increases the cutting forces required to remove material, which can cause the tool to vibrate. This is because a larger radius means a larger area of contact between the tool and the workpiece, resulting in higher cutting forces.
• Poor chip evacuation: Large nose radius can lead to poor chip evacuation, which can cause chip accumulation and tool damage. This is because a larger radius means a larger volume of material to be removed, which can clog the cutting tool.
Therefore, it is important to choose the appropriate nose radius for a given machining operation to avoid chatter and ensure good surface finish.
