In order to do a skilled job, the programmer and / or the operator from the CNC centres will apply an operational management through which all the programming and operating instructions for making a part will reproduce the practical actions that a worker classically does. The paper presents the 10 stages of computer-aided processing. The applied research showed that it is more and more necessary to shorten the programming time to make a part by switching from G code to high level code as shown intuitively in the Sinu Train application. At the same time, the management of the processing technology on the CNC centres imposes more and more, through the new working conditions given by the pandemic, work from home (home-work) and programming from home. Therefore, the online simulation of the program created is the new method of \"cold testing\" of a processing process. Finally, by operating on CNC centres, the compliance with the quality requirements given by the total quality management will always be pursued.","PeriodicalId":31066,"journal":{"name":"Robotica Management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69193234","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}
