Functionality and cost are two key factors for open architecture machine tools. Dynamic reconfiguration technology provides a method to achieve more functions at low cost. Hardware dynamic reconfiguration is special feature of FPGA devices. In this paper, a dynamic reconfigurable interpolator with linear, circular and NURBS interpolations is presented. The functions of interpolator can be reconfigured during machining. The requirement for logic resource on-chip reduces evidently, which makes it feasible to implement complicated interpolations using a limited area. Experimental results are presented to verify the performance of the dynamic reconfigurable interpolator.
