Abstract:
Precision machinery is an emerging industry that countries around the world value, but what is precision machinery? What is the difference between precision machinery and general machinery? Why is China still unable to produce high-precision processing machines, precision instruments, robotic arms and precision positioning platforms? This is not enough to understand the precision of precision machinery! Precision measurement technology should not only be used for product quality inspection, but also for product manufacturing equipment, sensing geometric errors caused by improper assembly of each axis, and compensating for spatial errors through the controller to improve accuracy. This report will provide an in-depth analysis of the causes of error in precision machinery. It will introduce the spatial error detection and compensation schemes of domestic CNC machine tools and robot arms, and introduce several innovative precision measuring instruments. I hope that you can accurately measure precision machinery. The importance of the above is known.
