A NOVEL TWO-MODE INTEGRAL APPROACH FOR THERMAL ERROR MODELING IN CNC MILLING-TURNING MACHINING CENTER

Thermal errors have the largest contribution, as much as about 70%, to the machining inaccuracy of computer-numerical-controlled (CNC) machining centers. The error compensation method so far plays the most popular and effective way to minimize the thermal error. How to accurately and quickly build an applicable thermal error model (TEM) is the kern...
