THERMONY
Thermal displacement correction system
The machined dimension values change as the machine temperature changes due to the user’s conditions of use (machining conditions) and the environmental conditions (factory temperature, etc.). This system predicts the amount of thermal displacement based on the temperature changes at various sections of the machine and provides compensation values to the CNC controller in order to minimize affects on the machining dimension values. When Thermony is not applied, the amount of change in the machined diameter over 8 hours is 15 μm, but when it is applied the amount of change is suppressed to 6 μm, exhibiting an improvement of 60%.
