Orthogonal Cutting and Friction Angle
Orthogonal cutting is a machining process in which a single-point cutting tool is used to remove material from a workpiece. The cutting action occurs at a 90-degree angle to the direction of tool motion, hence the term "orthogonal". The friction angle, also known as the rake angle, is an important parameter in orthogonal cutting.
Effect of Friction Angle on Cutting Force
Cutting force is the force required to cut and remove material during the machining process. The friction angle has a significant effect on the cutting force. The correct pair of statements regarding the effect of friction angle on cutting force is:
Q. Reduction in friction angle decreases cutting force.
This statement is correct because as the friction angle decreases, there is less resistance between the tool and the workpiece. This reduces the frictional forces acting on the tool, resulting in a decrease in cutting force.
D. Reduction in friction angle decreases cutting force.
This statement is also correct. The reduction in friction angle leads to a decrease in the tangential force component acting on the tool. As a result, the cutting force decreases.
Effect of Friction Angle on Chip Thickness
Chip thickness is the thickness of the material removed by the cutting tool. The friction angle also affects the chip thickness. The correct pair of statements regarding the effect of friction angle on chip thickness is:
R. Reduction in friction angle increases chip thickness.
This statement is incorrect. A reduction in the friction angle decreases the shear angle, which in turn decreases the chip thickness. Therefore, the correct statement would be that a reduction in friction angle decreases chip thickness.
S. Reduction in friction angle decreases chip thickness.
This statement is correct. As mentioned above, a reduction in friction angle decreases the shear angle, resulting in a decrease in chip thickness.
Conclusion
In summary, the correct pair of statements regarding orthogonal cutting using a single-point cutting tool are:
Q. Reduction in friction angle decreases cutting force.
S. Reduction in friction angle decreases chip thickness.
