Importance of Initial Diameter

1)Material Removal Rate (MRR): The initial diameter, along with the desired final diameter and length of the cut, helps in calculating the volume of material to be removed, which directly affects the material removal rate.
2)Cutting Parameters: It influences the selection of cutting parameters such as depth of cut, feed rate, and cutting speed. The depth of cut, in particular, is dependent on the difference between the initial and final diameters.
3)Machining Time: Knowing the initial diameter allows for the estimation of machining time. Larger initial diameters generally require longer machining times.
4)Tool Wear and Life: The initial diameter impacts tool wear and tool life, as larger initial diameters can result in more cutting forces and heat generation.
5)Dimensional Accuracy and Surface Finish: Accurate knowledge of the initial diameter is essential for achieving the required dimensional accuracy and surface finish in the final product.
