Embodiment Construction

[0015] After grinding, the surface processing damage caused by the grinding force and grinding temperature on the ceramic surface will directly affect the fatigue strength, fracture strength, surface hardness and wear resistance of the part, and it is also an important cause of surface cracks and surface breakage. When discussing the two important factors that affect the integrity of the surface, the surface mechanical performance index and surface morphology are analyzed. Experiments are designed to grind a variety of ceramic materials under different grinding conditions to obtain the ground surfaces under different conditions. Systematic theoretical analysis and experimental research on the processing damage of the ceramic surface after grinding are done.

[0016] The invention uses computer digital image processing technology and development tools to process the collected surface images of workpieces for various defects of the processed surface / subsurface in the high-effici...

Abstract

The invention discloses a ceramic processing surface damage detection system, which collects the processing status of the processing surface in the high-efficiency precision grinding process and the characteristic data of the grinding surface topography by the computer, and performs classification processing to obtain the edge contour characteristics of the damage, and identify The macro-quantitative index surface breakage rate, stability, diffusion and damage characteristic parameters that characterize the damage degree of the processed surface are extracted, combined with computer digital image processing technology and algorithms, to complete the detection and evaluation of ceramic surface processing damage. Compared with the existing technology, the system can effectively detect the surface damage type, characteristics, and surface damage degree of advanced ceramics and other related materials, and can be used as an important reference index for comprehensively evaluating the surface quality of ceramic processing. The detection software written in the system is simple and practical, low in cost, more conducive to popularization, reliable and effective, and has greater economic benefits.

Description

technical field [0001] The invention relates to a computer digital image processing technology, in particular to a system for realizing the damage detection of the ceramic processing surface by using the computer image processing technology. Background technique [0002] After grinding, the surface processing damage caused by the grinding force and grinding temperature directly affects the fatigue strength, fracture strength, surface hardness and wear resistance of the part, and is also an important factor that causes surface cracks and surface breakage. reason. Due to the damage or defect on the surface during processing or use, it is very easy to cause damage to the surface structure, resulting in a reduction in the strength of the part, or even scrapping. Therefore, it is necessary to identify and evaluate the damage degree of the machined surface, and the damage detection technology of engineering ceramic grinding surface is born from this. [0003] In order to solve t...
