This paper presents a scientific framework of a design tool that is capable of objectively registering development progression of new process modules for RMS. It uses `Qualitative Analysis' based on `Coding' combined with the method of `Structured Analysis Design Technique'. In five consecutive stages, the development progression is indexed.

In EHL theory, it is generally assumed that the rolling element is subject to a constant load, but in the dynamic analysis of rolling bearings, the load is unknown. Based on geometry and position relation of rolling elements, the convergence criterion of EHL theory is modified to meet the need of dynamic analysis of rolling bearings. Then the multi-grid method is employed to study the EHL of a ball bearing. This method is proved by the results and it can be used in the dynamic analysis of rolling bearings.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121521973","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}

Based on the proposed model, the effects of ball off size under different working conditions were investigated. In combination with machining error distribution theory, statistical analysis of bearing life was conducted. At last, 16008 deep groove ball bearing was selected to illustrate the modified life model. Through numerical calculation, the following conclusions can be drawn : 1) The life factors are normally distributed when the ball off sizes have normal distribution; 2) With the increasing of external load, the effect of ball off size on bearing fatigue life is weakened; 3) The effect of ball off size on bearing fatigue life is most obvious when bearing operates in a small negative radial clearance.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128853","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}

There are conventional methods to fabricate the micro channels such as lithography, etching and laser processing; however, they have some demerits of high cost, limitation of materials and complex processes. Machining molds with micro channel structures for mixers using micro end-mills have been studied. According to recent study, ultra micro end-milling technology is required in order to improve the efficiency of mixers because the micro structures are double-layered channels. Tool breakage and micro burrs are issues due to diameter of the micro end-mill getting smaller. Machining characteristics using Φ 50 and 30 μm end-mill on 64 brass and STAVAX were studied in order to machine the micro complex channels. Tool stability and burrs were studied through analysis of the cutting force and cutting conditions. A micro-mixer mold with double-layered channel structures was machined.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"41 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113983733","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}
