Which of the following expressions can determine the longitudinal feed rate in "Through Feed Centreless Grinding"?
(If the diameter of the regulating wheel = D, r.p.m. of the regulating wheel = N, angle of inclination of the regulating wheel = θ)
1
Longitudinal feed rate = Π x D x N x Sin (θ)
2
Longitudinal feed rate = [Π x D x N] / Sin (θ)
3
Longitudinal feed rate = Π x D x N x Cos (θ)
4
Longitudinal feed rate = [ Π x D x N] / Cos (θ)
