The paper deals with the method of interference-free tool attitude
determination for five-axis machining. Most of the present five-axis CAM
systems have a lot of restrictions concerning tool interference, object shape,
machining method, and so on. In this paper, an effective method is proposed,
which can determine an interference-free tool attitude on the basis of
the original two-dimensional configuration space.
Our configuration space shows the relationship between tool attitudes
and the existence of tool interference, taking the tool shape into account.
Furthermore, the proposed method enables us to reflect machining strategies,
that is, the user's machining intention on the basis of empirical knowledge.
The method has been experimentally found effective for generating
five-axis tool paths.
