This paper presents a method on the determination of tool profile for internal grinding of ball nut. The solution is based on the so-called derivation theory, where the parameters of the tool (tilt angle, profile points, approximated profile curve) are determined by numerical methods. The final approximating tool profile is an ellipse-arc where the data points for the approximation are the intersection points of the surface intersection curves. Points of tool profile curves are determined by an initial value problem of ordinary differential equation system (ODE-IVP). The fitting method of approximating ellipses uses a numerically stable noniterative algorithm.
