Approach to Compensation of Machine Tool Angular Thermal Errors Using Controlled Internal Heat Sinks and Sources
Original language description
Thermal errors caused by internal (motors, bearings, ball screws and their nuts, gear box, etc.) and external heat sources (effect of environment, machine operator, radiation etc.) can cause more than 70% of machine tool (MT) total error. Direct (measuring between tool and work-piece) and indirect (predictive models) approaches to compensation of thermo-dependent tool center point (TCP) displacement can be classified besides expensive redesign of a MT structure. Thermal error indirect compensation is one of the widely employed techniques to reduce the thermal errors. This contribution is a summary of recent scientific work on the modeling of highly nonlinear MT thermal errors with close attention to angular deformational elements occurring at the TCP.Thermal transfer functions (TTF) are used for the identification and control of additional internal heat sinks and sources. The applied method is dynamic and its modeling and calculation speed is suitable for real-time applications. The m
