Temperature change surrounding the machine tool causes complex thermal deformation of the structures such as bed and column, consequently causing machining error. We have developed unique and highly precise thermal error estimation method based on FEM. The method can calculate complex thermal deformation of the structures in real-time on CNC. We have applied the world's first real-time thermal error compensation system which features FEM analysis function to CNC on machining center and succeeded to dramatically decrease the machining error caused by temperature change.
