To understand why the ideal surface roughness produced on the components will increase by a factor of 4 when the feed rate is doubled, let's analyze the factors affecting surface roughness and how they are related to the feed rate.
Factors Affecting Surface Roughness:
1. Nose Radius: The nose radius of the cutting tool affects the depth of cut and the cutting forces. A larger nose radius will result in a smoother surface finish.
2. Feed Rate: The feed rate is the distance the cutting tool advances into the workpiece in one revolution. It directly affects the surface roughness, as a higher feed rate can lead to a rougher surface finish.
3. Depth of Cut: The depth of cut is the distance from the machined surface to the uncut material. It also influences the surface roughness, as a larger depth of cut can result in a rougher surface finish.
Effect of Feed Rate on Surface Roughness:
When the feed rate is doubled, the surface roughness will increase by a factor of 4. This can be understood by considering the following points:
1. Feed Rate and Depth of Cut: Increasing the feed rate while maintaining a constant depth of cut will result in a larger volume of material being removed per revolution. This increased material removal can lead to more significant variations in the machined surface, resulting in a rougher finish.
2. Feed Rate and Nose Radius: The feed rate and nose radius are inversely related when it comes to surface roughness. A larger nose radius can compensate for a higher feed rate, resulting in a smoother surface finish. However, when the feed rate is doubled, the effect of the nose radius becomes less significant, and the increased material removal dominates the surface roughness.
3. Surface Roughness Calculation: The ideal surface roughness (peak-to-valley height) is proportional to the square root of the feed rate. Therefore, when the feed rate is doubled, the ideal surface roughness will increase by a factor of √2. Since √2 ≈ 1.41, the ideal surface roughness will increase by a factor of approximately 1.41 × 1.41 = 1.99, which is approximately 2.
Hence, the ideal surface roughness will increase by a factor of 4 (2 × 2) when the feed rate is doubled. Therefore, the correct answer is option B.
