Description
【Technical field】 [0001] The invention relates to the technical field of precision machining, in particular to the technical field of precision machining precision monitoring systems. 【Background technique】 [0002] Precision machining has extremely high requirements for precision. Modern high-precision machining generally requires online monitoring. Various sensors are used to monitor the processing size parameters, and the data is integrated through the main controller to compare with the theoretical size. Processing Processing problems can be corrected in time during the process. However, on the one hand, too many sensors bring pressure on the equipment space. In the process of processing complex parts, the narrow space often causes spatial interference to the sensors. At the same time, too many sensors cause pressure on the multi-channel power output of the controller. , needs a more advanced multi-channel regulated power supply to supply power to meet the demand, which...
