The study deals with the development of control software to form
a so-called character line, which means an intersectional line
between two sculptured surfaces. The clear character line,
one of the most important elements to make high quality die and
mold products, is generally difficult to create by 3- to 5-axis
control machine tools with conventional rotational cutting tools
such as ball end mills, because there remains hardly removable
round on the character line. Thus, the round is normally removed
by hand lapping, which requires the skill and experience of workers.
In the study, a new approach is proposed to finish the character line
by using a non-rotational cutting tool, which is mounted on a
6-axis control machining center. Two machining methods to create
the character line are investigated from the viewpoint of surface
roughness and ease of creation, that is, one-path method and two-path
one. The former gives priority to removing remains formed in the
previous rough-finishing such as ball end milling. The latter places
emphasis on sharpening the character line. Based on these two methods,
6-axis control machining of character line was carried out. As a result,
it is experimentally found that 6-axis control machining enables the
creation of character line.
