The paper deals with the method of tool path generation for 5-axis
machining using a ball end mill. 5-axis machining has been used for
aircraft parts as well as for complicated shapes such as molds and dies.
However, most of the present CAM systems for 5-axis machining have limited
functions in terms of tool collision, workpiece shapes and machining methods.
For that reason, in many cases the optimal cutter location (CL) data cannot
be obtained or considerable time is consumed. To solve this problem,
we have applied a 3-dimensional configuration space (C-Space) and showed
the relationship between all tool positions and postures and the existence
of tool collision. The method of tool path generation devised in the study
enables users to generate CL data reflecting their own machining strategy
such as smooth change in tool posture and the state of machining without
considering the gouging. The validity of this method was experimentally
confirmed by successfully milling an impeller without tool collision
