Research On Variable Speed Grinding Roll Based On Adaptive Fuzzy Control

Traditional effective for increasing accuracy of roll surface and roll grinding methods are mainly focus on the change of the grinding wheel and work piece during the process of grinding, Mainly include axial stiffness at the weak point, considering the work piece center frame is designed in order to improve the stiffness of artifacts; Adopting grinding chatter suppression, error compensation and analysis of the mechanism of variable speed grinding machine tool, the measure such as variable speed grinding. Based on the analysis of the mechanism of variable speed grinding, variable speed grinding and grinding chatter suppression, on the basis of the relationship between the grinding accuracy, according to the specific material of the roll and roll profile structure, reasonable of the grinding wheel itself used grinding characteristics and specific grinding process parameters, Based on the direct adaptive fuzzy control of roll shifting micro feed grinding technology strategy. And give full consideration to roll grinder, roll system along the rolling roller to the change of stiffness and control of grinding roll deformation is proposed based on adaptive fuzzy control on the basis of variable speed grinding micro feed optimal adaptive control strategy,To improve the precision of the roll grinding is proposed a new method is a breakthrough,effectively solve.At present the application of the on-line measurement technology has been mature,and has wide application in the field of mechanical processing, to provide real-time processing parameters for machining, and to improve the efficiency, to protect the work piece and machine tool processing, reduce the machining error. On the basis of the advanced technical support, analyses the importance of rigid plank roll grinding test in the production process of and the roll profile and surface roughness detection method of limitations, Designed a kind of roll profile on-line measuring instrument, overcome the roll grinding curve movement of synthesis, And real-time measurement, feedback the main grinding roll grinding parameters, is proposed based on fuzzy control theory of on-line roll profile measurement method, realizes the intelligent measurement system of test in the application of the roll grinding.Online measurement data of acquisition and grinding are synchronous, and position prior to grinding system. Into the normal measurement processing operations, online measurement system for roll grinding system is the processing of roll surface roughness,roll profile and relevant data transmission to the fuzzy control system, fuzzy control systemwill measure data compared with ideal model, calculation. The final out put roll grinding the optimal grinding speed and grinding force, to obtain the ideal roll profile and roll surface roughness, realize the online measurement and adaptive control.
