Abstract

Mechanistic models assume that cutting forces acting on reamer flutes, especially the tangential forces, are proportional to chip cross sectional area. The constant of proportionality relating the cutting force and chip area are obtained through experimentation. Drilling process was used to formulate the proportionality constant in terms of specific cutting energy coefficients. In this paper, an attempt has been made to determine specific cutting energy coefficients using drilling operation for different materials and obtaining proportionality constants for machining. The paper also includes static force modeling for reaming operation and graphical presentation of the results
