Problems solved by technology

However, the above models are usually used for thermal error compensation in medium-sized or large-scale processing machine tools, and have not been studied for high-speed precision machining processes. Due to the different hardware structures, the distribution of the temperature field and thermal performance of the machine tools will be very different. Directly apply the original compensation model to the high-speed precision machining process, otherwise the inappropriate compensation function will reduce the machining accuracy

Description

technical field [0001] The invention relates to a device and method in the technical field of numerical control machine tool processing, in particular to a thermal error real-time compensation system and compensation method for high-speed precision machining. Background technique [0002] Precision and ultra-precision machining technology was formed and developed in the United States in the early 1960s due to the development of aerospace technology and military technology. With the increasing role of precision machining technology in promoting military technology, all countries have focused on funding and researching and developing it as a national key technology. The United States took the lead in promulgating the "Advanced Manufacturing Technology Plan" and "Manufacturing Technology Center Plan", and Germany formulated the "Manufacturing Plan". Japan also paid attention to the basic research of precision machining technology in the 1980s and applied it to the civilian hig...
