One of the important trends of precision machining is the development of real-time error compensation technology. By drawing on the mature experience of foreign countries and combining the research work of the R&D team in this field.

This technology has been applied to more than ten different types of machines, including: turning centers and machining centers; small, medium and large machines; new products and modified machines. The accuracy is improved by 3 to 10 times. Error sources for compensation include machine geometry and thermal errors, errors caused by cutting forces, and workpiece thermal errors.

The technology mainly involves the following aspects: general method of developing real-time error compensation system; formulation of error comprehensive model; machine error mapping; optimal modeling; thermal error mode analysis; optimization of sensor position; error compensation caused by cutting force; Implementation of compensation control; and other key issues in real-time error compensation technology.

These technological advances can better solve the problems that cannot be overcome by humans, and thus provide technical support for processing more high-precision non-standard products.
