Contouring Control of a Five-Axis Machine Tool with Equivalent Errors

In this study, the contouring control problem of a five-axis machine tool was examined. Due to rotation axes, there are two coordinate systems involved in tool, namely workpiece system and system. The is required follow given desired path with orientation specified However, dynamics described coordinates. Kinematic transformations exist between systems. One challenge design controller that will meet requirements Another minimize both position contour error error. method equivalent errors adopted controller. transformed into five-dimensional hyper-curve A designed using errors. Both numerical experimental results validate effectiveness proposed method.
