Influence Of Topography Of Diamond Circular Saw Blade Segments On Its Cutting Performance Based On Pattern Recognition

Possesses with sound cutting performance, the diamond circular saw blade iswidely used in stone processing. Since the abrasion of cutting tool is inevitableduring the cutting process, the saw-blade shall be timely dressed to ensure cuttingefficiency and quality. Dressing can also aggravate the abrasion, shorten its servicelife and increase the cost. The optimum cutting state is to reduce abrasion as possiblewhen dressing on the premise of ensuring efficiency and quality. And effectivelyassess the sawing capacity is the key to solve above question.This topic mainly studies the extraction and analysis process of topographycharacteristic quantity of diamond saw blade, evaluation of blade sawing capacity,relationships between topography characteristic quantity and sawing capacity. It alsoestablishes the corresponding relation between topography characteristics quantityand sawing capacity, achieving the effectively evaluation to blade’s cutting capacity.The main content is as follows:(1) The topic raises the characteristic quantity of reaction topography informationaccording to three frequency information of cutting topography (LF, MF, HF)respectively, and analyzes the significance and calculation method of eachcharacteristic quantity.(2) The BP neural network algorithm is applied to recognize diamond saw bladeabrasive grains for improving its recognition efficiency and quality. The height,gradient and second-order difference of three-dimensional topography acting asneural network input, grinding grain, binding agent acting as two types of output ofneural network to establish the network model, achieving the automatic recognitionto three-dimensional diamond grits. The example shows above method caneffectively recognize the grinding grain.(3) The operation interface of topography processing is designed in MATLABrunning environment, which is more convenient and efficient to process data. Inorder to obtain more topography data, the stitching algorithm is studied in my topic. And template matching method is used for topography data, obtaining a bettereffect.(4) Select a sawing force acts as an indicator to evaluate the cutting state. First,select the required quantity through related analysis between sawing force andtopography characteristic quantity; then, divide the topography data into four patterncategories which is relative blunt, general, relative sharp and sharp according tocertain principles. And the four pattern categories also represent four differentsawing capacities.(5) The application of algorithm of pattern recognition in identifying the cuttingstate first verifies the separability of sample data; then introduces the merits anddemerits of various discrimination function and criteria, chooses the appropriateform of discrimination function and discrimination criteria; finally, verifies theeffectiveness of discrimination function.
