Abstract
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, The process is modified 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, the application of curved surface interpolation is proposed, where all tool attitudes are calculated by interpolating some representative attitudes at cutting points. As a result, it is possible to generate the cutter location data by a fewer information in the short calculation time.
