ABSTRACT: This
paper introduces a reference-pulse interpolator motion control system, which
can be applied for computer numerical control (CNC) machine tools. The
interpolation is calculated in DSP and the independent pulse generator modules
are performed in FPGA, which can generate precise reference velocity profile
and eliminate the path error of reference pulse interpolation. The proposed
methodology has many advantages over existing reference-pulse interpolator
controller, such as: real-time, extensibility, high flexibility and high
precision motion profile planning.
