Some commercial 3-dimensional CAM software are already offered,
which consider the tool interference problem and allow us the
interference-free 5-axis controlled machining. However,
the policy of CAM software to the tool interference avoidance is
that the modification of tool attitude is done only at where the tool
interference is detected. Thus, the tool attitude suddenly changes
with the redundant movement, and causes the over and under cutting.
We have already proposed the tool path generation method using the
original configuration space. In the previous paper,
the interference-free cutter location with a minimum change
in tool attitude was generated while referring to all of the
configuration space information at several cutting points.
In this study, all tool attitudes are decided by referring to
the configuration space information of an entire machining surface.
The continuousness of tool attitude change in the direction of not
only tool feed but also pickfeed is considered, and the tool path
generation method for the optimum 5-axis controlled machining is
developed. As a result, the usefulness of the devised CAM software
is experimentally confirmed.
