The controller circuit is supported with multi-task and efficient algorithms. The proposed controller circuit surpasses the existing controller boards in terms of its lower power consumption, low cost, and compact size.

Based on the ideas described, a pilot system for use in interactive surface modelling (ISM) on a personal computer CAD system has been implemented. The ISM system combines company and national standards with geometric representation of 2-D and 3-D surfaces. The system allows the user to interactively construct and simualte 3-D surfaces in the CAD-system with the use of the surface's “key” function parameters. Separation of function components makes it possible to simulate 3-D surfaces with desired properties interactively by the method of “mathematical machining” presented in this paper.</p></div>","PeriodicalId":100666,"journal":{"name":"Industrial Metrology","volume":"2 2","pages":"Pages 107-119"},"PeriodicalIF":0.0,"publicationDate":"1992-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0921-5956(92)80024-N","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91680913","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}

Compared with traditional methods, which normally employ a variety of separate instruments, CMMs are fast in operation and are adequately accurate for many applications. However, accuracy limitations often inhibit their use for high precision metrology. Accuracy is limited by such factors as straightness and orthogonality of the CMM movements; established techniques exist for determining these factors. In many cases, the errors introduced by the probes are very significant and often exceed the errors from other sources. This paper describes an investigation into the nature of probe errors, the factors that influence their performance and proposes a method of verifying the probe performance. Results from a number of probes used in different modes are presented. The application of the work to linking CAD systems to CMMs is briefly described.</p></div>","PeriodicalId":100666,"journal":{"name":"Industrial Metrology","volume":"2 1","pages":"Pages 59-70"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0921-5956(91)80025-B","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91759065","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}
