Thermal Error Modeling of a Horizontal Machining Center Using Fuzzy Logic Strategy
2001
Thermally induced errors originating from machine tool errors have received significant attention recently because high speed and precise machining is now the principal trend in manufacturing processes using CNC machine tools. The performance of a thermal error compensation system basically depends on the accuracy and robustness of the thermal error model. This paper presents a thermal error model using a fuzzy logic strategy, which does not require any complex procedure such as multiregression or information about the characteristics of the plant. Accordingly, the proposed modeling method can be applied to any type of CNC machine tool as the error model parameters are only calculated mathematically, plus the error model provides good accuracy and robustness.
