Description

technical field [0001] The invention relates to numerical control machining technology, in particular to a method for automatically measuring the angle of numerical control machining. Background technique [0002] The online measurement technology currently used on CNC machine tools is mainly based on three-coordinate measurement, while most parts on aero-engines are mainly ring parts, with many centripetal angle features, and most of them are parts processed by four-axis or more than four-axis , it is necessary to measure the angle data of the part. More and more parts are produced using existing processing technology, and the ability to control the rotation angle of machine tools and the measurement of part angle features is relatively limited. Traditional processing technology must use manual measurement methods to ensure the processing quality of parts, low processing efficiency, and human influence. The factors are large and the labor cost is high. With the continuous...
