The study deals with the tool attitude determination for 5-axis control
machining, considering the interference between the tool and the workpiece.
CAM systems capable of interference-free tool path generation are strongly
required. To solve the problem, 2-D C-Space was proposed, which expresses
the relationship between the tool attitudes and the tool interference.
In this study, CAM system is improved to shorten the calculation time of
the interference and to increase the robustness in the calculation stability,
using linear C-Space. As a result, a new CAM system shows the potential of
producing complicated shapes like a closed impeller with overhanging parts.
