This study deals with the method of collision avoidance in the automatic
tool path generation for 5-axis control machining. The 5-axis control
machining offers the potential of efficient and accurate machining,
while the collision between a tool and surrounding objects is still
a severe problem. The method devised in this study realizes the judgment
on the possibility of collision avoidance at the position where the
collision take place, and produces the direction of collision avoidance,
based on the 2-dimensional configuration space (C-Space) defined by two
parameters which determine the tool posture. This method allows a test
workpiece with overhanging parts to be actually milled without collision.
As a result, the validity of the method is experimentally confirmed.
