It takes a long time to determine the proper EDM conditions for the finish cut because many test cuts of the workpiece are required. In this study, we investigate and discuss the EDM conditions and servo feed functions of the finish cut, by examining relationships between the wire behaviors and the wall straightness of the workpiece. A method of determining EDM conditions for the finish cut is described, based on a balance model of electrostatic force and discharge force acting on the wire. A servo feed function responding to the variation of skimmed depth is investigated. Control methods for responding to the height variation of the workpiece at the finish cut are discussed.","PeriodicalId":269071,"journal":{"name":"Journal of the Japan Society of Electrical-machining Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128140784","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}

With powder mixed oil, the removal rate was improved due to discharge dispersion. However, contrary to expectations, the surface roughness was not sufficiently improved by using only the powder mixed oil, since a long pulse discharge that exceeded the settled pulse duration was generated. This phenomenon is often observed in the case of EDM of a high-resistivity material. In order to obtain a smooth surface, the machining was carried out under limited pulse duration with powder mixed oil so that the long pulse could not be generated. Tests revealed that the removal rate in drilling Si3N4 by EDM was almost the same as that by the grinding process and the surface roughness was reduced to 4μmRy.","PeriodicalId":269071,"journal":{"name":"Journal of the Japan Society of Electrical-machining Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420810","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}

Since the development of WEDG (wire electro discharge) technology, micro-EDM has become an excellent method for machining microholes on metals and alloys.

In this paper a new system is proposed for machining microholes, called the Tandem micro-EDM system. The new system is not only for machining microtools but also for machining microholes at the same time. As a result, the Tandem micro-EDM system can machine a great number of microholes continuously after spindle setup.","PeriodicalId":269071,"journal":{"name":"Journal of the Japan Society of Electrical-machining Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127697237","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}

Die steels are sparked with electrodes of cermets containing both borides (TiB2, ZrB2) and metals (Co, Ni) in argon atmosphere. A conventional NC EDM machine is used as a pulsed arc generator. A transistor-controlled capacitor circuit is adopted to obtain steep and high current electrical pulses promoting transfer of the electrode materials. Coatings of borides, which are difficult to build up, are deposited onto the substrates. Surfaces of the coatings are irregular and thickness varies in the range of 10 to 50um. No cracks are observed in interfaces between the coatings and the substrates. Vickers hardness value (0.098N load) changes between 1,000 to 3,200 Hv depending on both thickness of the coating and the electrode materials. Wear-out test is performed to investigate wear resistance of the coatings. Although the substrates without a coating are severely worn, the wear impression of the coated substrates is terminated in the coatings. An electrode mass transfer mechanism is observed. The electrode material is not transferred by a single discharge but by a highly concentrated discharge that occurs occasionally at arbitrary locations. key words: EDM, surface modification, electrode transfer, boride 1. はじめに 近年, 放電加工法を表面改質へ応用する様々な 試みがなされている1)4). なかでも, 放電加工油 中で電極材を放電により溶融 ・飛散させ改質層を 形成する手法においては, 硬質な皮膜が形成 され ている. 実用面でも, プレス金型, 冷間鍛造金型 および切削工具へ適用し, 優れた耐摩耗性を有す ることが確認されている5). しかしながら, 放電 加工油中で改質を行っているため, 加工油が放電 により分解 して生 じた炭化雰囲気中で改質を行 う ことになり, この手法では形成できる改質層は炭 化物に限定されている. 一方, 放電加工油を用いずアルゴンなどの不活 性な気中で放電を発生させ電極材を移行 し改質層 を形成するならば, 用いる電極材に応 じて, 炭化 物のみならず金属, 窒化物, およびホウ化物など 様々な組成の改質層を形成可能 と思われる. 気中放電を用いた表面改質法 としては, 古くか ら放電被覆法が知 られており, 超硬合金成分をは じめとする様々な組成からなる改質層が形成 され ている6). 奥宮らは酸窒化物を含む改質層が形成 可能なことを報告している7). さらに, 表面改質 ではないが, 早川 らにより電極の移行 ・付着現象 * 電 気加 工 学会 全 国大 会(1999)に て 発表 **神奈 川 県産 業 技術 総合 研 究所(海 老 名 市 下 今 泉705-1) E-mail: satsuta@kanagawa-iri.go.jp","PeriodicalId":269071,"journal":{"name":"Journal of the Japan Society of Electrical-machining Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115746583","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}

Since the development of WEDG (wire electro discharge grinding), micro-EDM has been an excellent process for machining microholes in metals and alloys. However problems remain in machining the high-aspect-ratio holes. As the depth of microholes becomes deeper, drilling through the microholes becomes more difficult. In addition, the removal of debris and renewal of dielectric from the machining gap are difficult because unstable discharge and arcing usually result. In this study, the jump flushing system is proposed for drilling microholes with high aspect ratios, by inducing an intermittent jump of the workpiece. The system is assisted by the horizontal main spindle and pure water dielectric. As a result, a 1.5mm-deep hole with the diameter of 100μm was successfully machined in to stainless steel which is one of the more difficult materials in which to drill deep microholes.","PeriodicalId":269071,"journal":{"name":"Journal of the Japan Society of Electrical-machining Engineers","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133633672","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}
