 · Ozturk et al. calculated boundary of CWE for milling by ball end mill analytically, and the method was proved to be more efficient than the ZMap method for CWE [12, 13]. But, the abovementioned methods are difficult to apply to 3D milling (the vector of tool axis is varied during machining). Sun and Guo used the Newton iteration method to calculate the boundary of CWE .

 · Traditional end milling formulas use Surface Footage (SFM) and Chip Load (IPT) to calculate Speed (RPM) and Feed (IPM) rates. These formulas dictate the correct machining parameters for use in a linear path in which the end mill's centerline is travelling in a straight line. Since not all parts are made of flat surfaces, end mills will invariably need to move in a nonlinear path. In the ...
