The WEDM workcenter used in this research is a JAPAX 4G. The unit uses nozzles to guide the wire and apply the dielectric fluid to the workpiece. The wire is the conductive electrode and the dielectric fluid produces a localized ionized field between the workpiece and the wire. The dielectric fluid also, clears the debris and cools the wire. The most common problem in WEDM is the optimization of cycle times. The amount of time needed to produce a finished part determines the profitability of the workcenter. Industry is continually searching for procedures to decrease cycle times and increase profit. This research uses a design of experiments (DOE) method to optimize the WEDM process.\u0000 The key parameters of the WEDM process are modified during the DOE trials. The results are applied to produce an optimal machining condition. The three conditions: Manufacturers Settings, E-Chip Settings, and Optimized Settings are used to produce the rough-cut of three identical designs. The rough-cut is the first pass to produce a finished workpiece. It is during this pass that material removal rate and the risk of wire rupture are the greatest. The overall cycle time is mainly impacted by the time required to perform the rough-cut. The three designs produced are examined for surface finish. The key parameter settings that are used during the rough-cut must not produce a surface finish that requires the addition of cutting passes to produce the final design. Also, the risk of wire rupture during the rough-cut must be acceptable. If wire rupture were to occur during the rough-cut then all benefits of increased speed are lost.","PeriodicalId":383495,"journal":{"name":"Applications of Design for Manufacturing","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129104688","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 was accomplished utilizing rules based on known machining practices developed in conjunction with Cadkey and Cutting Edge designers. The rules used for designing this software consist of fundamental principles of machining. In the conventional approach, these are the rules that are supplied by the designer and applied to the problem using a programs such as Cutting Edge. The basic set of rules and the original Computer-Aided Design (CAD) design were sufficient to create the needed tool paths with the user’s time and input replaced by a computer algorithm. A developed computer algorithm is much less flexible, but significantly quicker than a designer, so where applicable more robust rules which required greater time or iterations were chosen. The algorithm is general but can be applied to any CAD system. However, the specific design work was performed with Cadkey as the target low cost system and a Roland desk-top Computer-Aided Modeling Machine (CAMM-3) as the target cutting device. All assumptions made for this test case were based on the criteria of user’s convenience and economy. All the tests performed proved that the algorithm works and is capable of adding one more output device — a cutter as an output system.","PeriodicalId":383495,"journal":{"name":"Applications of Design for Manufacturing","volume":"728 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127208629","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}

Out of specifications surface parameters will often be confined to less than quality making features and hence affect manufacturability. There is an eminent need for a methodology that enables process designers to evaluate and improve the quality manufacturability of the milling process before machining. This paper describes a methodology of design for quality manufacturability that enables product designers to evaluate, quantify and improve surface roughness in the design stage for milling operations. Different experiments have been conducted to measure cutting forces and surface roughness parameters under dry cutting conditions. The relationships between different operating parameters to the cutting force and surface roughness parameters were examined through extensive experimental work. Different relationships have been developed between five surface roughness parameters and three operating parameters. Further analysis has been conducted on the cutting force pattern: seasonal pattern, nonlinear trend and peak. The results generated from the study are very important for the parameters’ design of manufacturability for the milling operation. The basis for the design for quality is a set of common classes of quality defects (errors), and a set of factors that influence the occurrence of the less quality. The concept of quality errors and the derivation of the index matrix are presented.","PeriodicalId":383495,"journal":{"name":"Applications of Design for Manufacturing","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123318579","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}
