Abstract: 

PAM (Principle Axis Machining) is introduced as an effective way of milling free-form surfaces on 5-axis machines. PAM matches the minimum principle curvature of Toroidal end mill to the maximum principle curvature of the surface at the machined points via tool inclination in two directions. An investigation is made, herein, for comparison of surface roughness in milling with 3 end mills (flat-bottom, ball-noise, and Toroidal). This is done, first, theoretically based on tool/surface geometry along and across feed directions, and then evaluated according to some typical test results.
