HOREJŠ, O., M. MAREŠ, and J. HORNYCH. Real-time compensation of Machine Tool Thermal Errors Including Cutting Process. Journal of Machine Engineering. 2015, 15(3), 5-18. ISSN 1895-7595.
This paper presents a real-time compensation of three-axis vertical milling centre thermal errors including the cutting process effect. The simulation is based on dynamic modelling using transfer functions. The model was implemented into a standard CNC controller of a three-axis vertical milling centre to compensate for thermal errors in real time. The inputs of the compensation algorithm are the spindle rotational speed, the 5 temperatures of the machine structure and spindle power. A reduction of thermal errors achieved by using the new approximation TF model including cutting process impact is up to 79% for steel cutting tests with different cutting conditions.
