Dimensional error analysis and its intelligent pre-compensation in cnc grinding

Dimensional error appears nonlinearly in the computer numerical control (CNC) grinding process. The analysis of dimensional error variation for CNC grinding of cutter inserts is presented in this paper. A new intelligent error pre-compensation technique, the intelligent CNC system structure with which this is implemented, and the algorithm are introduced. The input-output response and the simulation of the intelligent error compensation system are also presented, and show the superiority of the technique.
