The 5-axis control machining is one of useful methods supporting
the reduction of production cost and delivery time. On the other hand,
there is a severe problem of interference between the tool and
the surrounding objects. In order to solve the tool interference problem,
we developed a path generation method using the concept of
the configuration space in our previous study. However,
the calculation of borderlines of areas in the configuration space
is based on the curve interpolation. Thus, the calculation requires
excessive time. In the present study, we modify the process by changing
the curve interpolation to the linear inter interpolation, which
results in shortening the calculation time of the interference-free
area and increasing the robustness of calculation. Moreover,
we propose the application of curved surface interpolation.
This method calculates all tool attitudes by interpolating some
representative attitudes at cutting points.
Thus, the cutter location data can be generated by a fewer information
in the short calculation time.
