Abstract
A new kind of rotational paraboloid end mill is proposed for the machining of sculptured surfaces in mould industry. Then
the mathematical models of continuous cutting edge curve with constant helix angle and the orthogonal spiral cutting edge of rotational paraboloid end mill is presented. Then
all curves are simulated based on MATLAB software. Finally
the rotational paraboloid end mill is manufactured using a SAACKE UWIF CNC grinding machine. The validity of the mathematical models and the feasibility of rotational paraboloid end mill are verified.
