Embodiment Construction

[0008] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0009] Such as figure 1 As shown, the roll grinding motion is a special grinding process formed between the CNC roll grinder, the grinding wheel, and the roll. Therefore, in the study of roll grinding mechanism, the influence of roll grinding motion parameters on grinding accuracy is considered based on the grinding geometric relationship.

[0010] In constructing adaptive systems (such as figure 2 Under the premise of the dotted line box), the parameters are initialized, and the optimal roll speed is output through the adaptive control system calculation. In the micro-feed formula The optimal feed speed is output under control, so that the motor movement and machine tool work are controlled, and then the cutting force of the grinding wheel and the roughness of the roll are fed back during the processing, and then the optimal output is controlled ...

Abstract

The invention aims at providing a roller variable-speed grinding scheme, particularly a self-adaptive micro-feeding roller variable-speed grinding intelligent control scheme. On the basis of analysis of the relationship between a variable-speed grinding mechanism, the variable-speed grinding and grinding chatter suppression, and the grinding precision, the invention provides a variable-speed grinding technological strategy based on self-adaptive fuzzy control, and the variable-speed grinding technological strategy is used for reasonably determining the characteristic and grinding technological parameters of a grinding wheel according to the texture and the structure of a roller. The method has the advantages that direct self-adaptive control is adopted, a fuzzy logic system for a self-adaptive learning algorithm is provided, the learning algorithm adjusts the parameters of the fuzzy logic system according to data information, the stability and the approximate intelligence of a control system can be guaranteed, and the grinding precision of the surface of a roller grind is effectively improved; the system is simple, operation is convenient, application and popularization are easy, the practicability is high, and good industrial benefits and social benefits are achieved.

Description

technical field [0001] The technical invention relates to self-adaptive fuzzy controlled micro-feed roll variable speed grinding, especially the intelligent control grinding of the surface roughness and roll shape of large sticks. Background technique [0002] The traditional method to improve the grinding precision is mainly to consider the changes of the workpiece and the grinding wheel during the grinding process, including: considering the weakest axial stiffness of the workpiece; using the steady rest to improve the stiffness of the workpiece; taking error compensation and analyzing the variable speed grinding grinding mechanism, variable speed grinding and grinding chatter suppression measures. The traditional grinding method cannot meet the ideal requirement of micro-feed intelligent control grinding, and there are large errors. Contents of the invention [0003] The purpose of this technical invention is to provide an adaptive micro-feed roll variable speed grindi...
