The interpolator plays the role of generator of axis movement data from the block data generated by the interpreter and is one of the key components of CNC, reflecting its accuracy. In this chapter, the various software interpolators will be introduced and their strengths and weaknesses will be described. In addition, a NURBS interpolator, which is an advanced interpolationmethod, will be described and the implementation algorithm will be introduced.
