Abstract
A rifling angle calculating method according to the present invention expands a rifling angle by combining a Fourier function and a polynomial function to take only the advantages of the two functions, and thus boundary conditions at the start and end points of the rifling angle may be faithfully satisfied, and an optimum rifling angle for minimizing the maximum rifling force may be calculated.
