Peoples pay more and more attention to the performance changes of mechanical system caused by reasonable wear model use. In this paper, combining with the development of the wear model, introduces the numerical simulation of wear model by using the integration size as a principal character. The forms, characteristics and applicability of these models are discussed. The numerical simulation model shows that the wear coefficient as a specific parameters in the system, which can be determined by experiment. The main factors affecting wear accuracy is the dynamic changing of the contact pressure which changes because of the geometry update, should be obtained by the numerical method. Using the numerical simulation method in the treatment of time-consuming problem, by selecting the different integration size, obtaining to the simulation results. Numerical simulation model of high accuracy, but more expensive, need to find a special measure to solve the problem of computing time, mathematical models can provide solutions for this.","PeriodicalId":354924,"journal":{"name":"2018 IEEE 9th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117219803","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}

Milling was conducted in dry and flood condition while varying spindle speed from 120 to 180 rev/min, depth of cut ranging from 1 to 2 mm as the feed rate was kept constant at 4.6 mm/min. The surface temperature was also measured during milling operation. It was found that during dry milling the surface roughness increased with increment of spindle speed where a maximum surface roughness value of 0.35 μm was recorded at 180 rev/min. During flood milling dry milling, the surface roughness increased with the increase of spindle speed, reaching a maximum of 0.25 μm at 180 rev/min. The depth of cut also had the same impact as spindle speed as it was found that during both dry and flood milling, the surface roughness increased with increment of depth of cut. Flood milling generated smoother milled surface as opposed to dry milling.","PeriodicalId":354924,"journal":{"name":"2018 IEEE 9th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115209248","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}

This paper proposes a novel approach to realize the panoramic navigation of the underwater cleaning robot. First, we select several feature points manually to calculate the images' relative location. Second, we solve the transformation matrix from the original view to the front view. Third, we build a matrix library marked by the robot's attitude. Fourth, the panoramic navigation system makes the real-time image projection and stitching based on the attitude of the robot. We use the fade-out fusion to eliminate the image stitching gap, which is time-efficient. This panoramic system uses the pre-set parameters to make the real-time image process, instead of doing the feature detection or matching, which could increase the efficiency significantly.","PeriodicalId":354924,"journal":{"name":"2018 IEEE 9th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116907721","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}

It becomes a critical issue for corporates pursuing the profits and maintaining the competitiveness through an appropriate technology transfer method in new materials field. Technology transfer is a part of innovation process. Technology transfer is the process let the technology from individual or organization transfer to the other. However, little has been done in discussing the topic. Consequently, the main purposes of this research are to evaluate the critical criteria and select the most suitable technology transfer method in the new materials by Fuzzy AHP approach. Two major findings can be shown as follow: Firstly, the criterion “characteristics of technology” win the highest weight, followed by the criteria “features of technology provider”, and “features of technology receiver”. Secondly, licensing method and joint venture of R&D are the two most appropriate technology transfer methods in the new materials field.","PeriodicalId":354924,"journal":{"name":"2018 IEEE 9th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129075807","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}
