Abstract:
On the basis of
study on the mathematical model of 3-dimensional ruled surface
(RS), this paper introduces a new concept of distance parameter
(DP) and also puts forward that the method of modeling a RS
depends on not only two boundary curves but also DP. According
to above theory, the formulas to calculate corresponding point
coordinates to any kind of top and bottom profile of a workpiece
and formulas to calculate the maximum inclination angle of
ruling line have been obtained. Then a different top and bottom
RS machining method including profile with line-are combination
as well as parametric curves has been achieved by 4-axes
simultaneous control programming proposed.
Key words:
