[0002] Internal electrolytic grinding is a special electrochemical machining method, which is usually used to process inner circular holes and metal workpieces with complex shapes. Internal electrolytic grinding mainly uses the combined action of electrochemical dissolution and mechanical grinding to efficiently and accurately process inner circular holes and metal workpieces with complex shapes.

[0003] At present, in traditional processing, the wear state of the grinding wheel is usually judged based on the subjective experience of the machine tool operator. This method cannot qualitatively evaluate the grinding process, and it is difficult to make an accurate judgment on the wear state of the grinding wheel, and cannot ensure high-quality and efficient grinding processing. As a result, in actual production and processing, machine tool operators often dress the grinding wheel in advance or frequently based on their own processing experience, so as to reduce the impact of grinding wheel wear on grinding quality. However, this grinding wheel dressing method will inevitably lead to excessive wear of the grinding wheel, thereby affecting processing efficiency. Utility Model Content
