{"title":"On the Relationship between Micropitting and Friction/Wear of Rolling-Sliding Steel/Steel Contacts","authors":"Xiaojing Wang, Yang Dong, Jingjing Zhang, Dan Bai, Hui Cen","doi":"10.1145/3560453.3560465","DOIUrl":"https://doi.org/10.1145/3560453.3560465","url":null,"abstract":"Micropitting phenomenon has been extensively studied in previous studies while the mechanism of micropitting formation process with relationship to friction and wear performance is scarcely researched. In this paper, two commercial lubricants were tested in a micropitting rig at different slide to roll ratios and relative humidities to evaluate the relationship between tribological performance and micropitting level. An optical microscope was applied to obtain the micropitting level on the contacting surface after tribological tests. The results showed higher relative humidity and slide to roll ratio always leaded to higher wear, while the friction change did not have a universe trend. The micropitting level was a combined effect of friction and wear. To explain this complex phenomenon, two mechanisms of the relationship between wear and micropitting performance were introduced. The two mechanisms were highly related to the propagation speed of micropits formed from small etching cracks and the removal speed of micropits due to wear. The outcome of this paper is beneficial to the evaluation of the performance of lubricants applied in rolling-sliding contacts.","PeriodicalId":345436,"journal":{"name":"Proceedings of the 2022 3rd International Conference on Robotics Systems and Vehicle Technology","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116552300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CNC technology is the development of new high-tech industries and cutting-edge industrial enabling technology and the most basic equipment. Manufacturing technology and equipment is the most basic means of production of human production activities, and CNC technology is today's advanced manufacturing technology and the most core technology of equipment. Therefore, the competition of machinery manufacturing is the competition of CNC technology. CNC technology is the use of digital information on mechanical motion and work process control technology; is the manufacturing industry to achieve automation, flexibility, integrated production basis; is to improve product quality, improve labor productivity essential material means; is an important strategic material for national defense modernization; is related to the country's strategic position and reflects the level of national comprehensive national power important basic industry. Today, the world's manufacturing industry widely used CNC technology to improve the manufacturing capacity and level, to improve the dynamic and changing market adaptability and competitiveness. Vigorous development of CNC technology as the core of advanced manufacturing technology has become the world's developed countries to accelerate economic development, improve comprehensive national power and national status of an important way. In addition, the world's industrial countries will also be CNC technology and CNC equipment as the country's strategic materials, not only to take significant measures to develop their own CNC technology and its industry, but also in the \"high precision\" CNC key technology and equipment to China to implement blockade and restrictive policies. Numerical control machining is one of the core production technologies of today's machinery manufacturing enterprises. Numerical control tool is an important part of numerical control processing, whether to choose and reasonable use, effective protection of the appropriate numerical control tool, directly affect the numerical control processing process, thereby determining the economic benefits and core competitiveness of numerical control manufacturing enterprises. Based on the analysis of the present situation and development trend of tool protection at home and abroad, combined with the present situation of small and medium-sized enterprises in our country and the needs of the protection of CNC tools, a set of suitable for the development of enterprise CNC tool selection and protection system is developed.","PeriodicalId":345436,"journal":{"name":"Proceedings of the 2022 3rd International Conference on Robotics Systems and Vehicle Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114630464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, real-time recognition of obstacles in constant motion is important. Considering the processing resources of the robot, it is difficult to achieve real-time recognition by using conventional computational methods. Therefore, inspired by the mechanism of selective attention in the human visual system, we developed an obstacle-recognition method. With this method, multiple obstacles can be recognized, and successful real-time recognition of multiple obstacles is possible by significantly reducing the required processing resources.","PeriodicalId":345436,"journal":{"name":"Proceedings of the 2022 3rd International Conference on Robotics Systems and Vehicle Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129769836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
