Researching Of The Determination Method Of Honing Workpiece's Inside Surface Sharp

Honing grinding is a kind of special form, is one of the high precision processing method. This process is not only can purify larger machining allowance, and is a kind of improving parts size precision, geometry precision and surface roughness effective processing method. The non-contact pneumatic measurement technology is introduced into the inner hole diameter size online measurement of nangjing, through inner hole diameter size change feedback to nangjing control system for further analysis and control, thus help improve the machining honing honing machines for processing precision.Because the honing processing technology, is deficient in the machining process, workpiece will appear different process defect. Judgment of the type of process defect, the subsequent process of honing lamilloy. In view of the above process defect, use contactless pneumatic measurement data acquisition, processing, complete honing the inner surface of workpiece shape judgement. This paper made the following two aspects of research:1. Choose contactless pneumatic measurement, and based on the measurement of non-contact pneumatic head design parameters of nangjing. Establish machine tools, measuring system was proposed for honing the establishment of the online measurement methods. Coordinate Through the analysis of the technology of nangjing process defect, according to different types of reason, this paper puts forward a kind of defects judge method, namely three section measuring determinant method. And puts forward its mathematical model algorithm, in order to verify the effectiveness of the algorithm, use Java, compiling simulation program within three section method workpiece surface shape judge judge simulation.2. The surface of workpiece honing within the cylindricity evaluation in cartesian coordinate system, under the cylindricity error evaluation model of the launched a detailed research. Before the cylindricity error with approximate method. By using least square method, through the model established the roundness error cartesian coordinate system, the straightness error evaluation the inner surface of workpiece cylindricity.
