Explanation:
To improve surface finish without sacrificing material removal rate during turning of a low carbon steel bar with a TiN coated carbide insert, the nose radius of the cutting tool should be increased. This will help achieve a better surface finish by reducing the contact area between the tool and the workpiece, resulting in less friction and a smoother surface.
Reasoning:
When turning a low carbon steel bar, the main objective is to remove material efficiently while also achieving a good surface finish. The choice of cutting parameters and tool geometry plays a crucial role in achieving this balance.
Increasing nose radius:
Increasing the nose radius of the cutting tool has several advantages in improving surface finish without sacrificing material removal rate:
1. Reduced contact area: By increasing the nose radius, the contact area between the tool and the workpiece is reduced. This reduces the friction and heat generated during cutting, resulting in a smoother surface finish.
2. Reduced cutting forces: A larger nose radius helps reduce cutting forces, as it distributes the load over a larger area. This reduces the tendency for the tool to dig into the workpiece, resulting in a better surface finish.
3. Improved chip control: A larger nose radius allows for better chip control, as it provides more space for the chips to flow away from the cutting zone. This prevents chip recutting and the generation of built-up edge, which can negatively impact surface finish.
Other options:
The other options mentioned in the question are not the correct choices for achieving an improved surface finish without sacrificing material removal rate:
- Decreasing nose radius and increasing depth of cut: Decreasing the nose radius would increase the contact area and friction, resulting in a poorer surface finish. Increasing depth of cut may increase material removal rate, but it can also lead to higher cutting forces and poorer surface finish.
- Increasing feed and reducing nose radius: Increasing the feed rate may increase material removal rate, but it can also lead to higher cutting forces and a poorer surface finish. Reducing the nose radius would increase the contact area and friction, further deteriorating the surface finish.
- Increasing depth of cut and feed: Increasing both the depth of cut and feed rate may increase material removal rate, but it can also lead to higher cutting forces and a poorer surface finish.
Therefore, the correct option to achieve an improved surface finish without sacrificing material removal rate is to increase the nose radius of the cutting tool.
