| Abstract: | The principle and algorithms for 4-axis machining are introduced in detail. A new method is proposed that generates tool axis by the intersection between the plane perpendicular to rotary axis and the cone formed in terms of the tangent direction and lead angle. The method is novel, clear, reliable and easy to realize on micro computer. It will be of practical value in manufacture of sculptured surfaces. |
