The Inaccuracy of Compensation System of Spindle Thermal Growth in Machine Tool Application and Its Solution

The development of machine tool is toward high-speed, high-precision and smarter with high-end compensation techniques. The sensor and the data acquiring system are required in compensation system. However, the aliasing phenomenon can be observed in the existing data acquiring system in machine tool application. In this paper, one solution is proposed to overcome signal aliasing. The phenomenon which appears in spindle thermal growth compensation system is carried, and the improved system. is validated.
