In recent years, five-axis controlled machine tool attracts attention from the increase in demand for improvement of productivity. Five-axis controlled machine tool which is added two axes for rotating and tilting to three translational axes, and can give arbitrary tool attitudes for a workpiece. Therefore, it has advantages to show as follows.
(a) It can process a complicated shape including overhang parts.
(b) It can keep a constant tool attitude against machining surface.
(c) It can lengthen tool life by preventing to cut at tool top part.
In previous researches using the original two-dimensional configuration space (C-Space), the tool path generation method for five-axis controlled machining by using an end mill had been proposed. The two-dimensional C-Space can express one tool attitude in only one point on the two-dimensional space, and replace the complicated geometrical issue such as the tool interference avoidance in real space with a simple problem of moving plan for one point in C-Space. The techniques of previous researches can generate tool path that considered tool interference, movable range of driving axes of machine tool, and continuity of tool attitude change, etc. However, it supported only the process with a ball end mill, and was insufficient at a point of flexibility.
In this report, we extend the technique of previous researches and propose the tool path generation method for five-axis controlled machining which utilized the advantage of square end mill to have much cutting removal rate.
