The study deals with 5-axis control tool path generation for machining
sculptured surfaces by using a conicoid end mill. The sphere part of
a ball end mill is in general utilized in case of machining sculptured
surfaces having a wide variety of curvatures. However, it takes much
time to machining such complicated sculptured surfaces with high
accuracy because of the necessity of small amount of pick feed,
which causes the reduction in machining efficiency. To solve this problem,
we devised a conicoid end mill and developed the main processor of
machining a swept surface by use of paraboloid end mill, which is a kind
of conicoid end mills. The adequate selection of cutting edge part allows
a large amount of pick feed and a good surface roughness in finishing.
As a result, it is experimentally found that the conicoid end mill for
potential of machining a sculptured surface with high accuracy and
efficiency.
