These errors determine the forming of the dimensional and shape accuracy of a machine tool. Diagnostically evaluated were: the deviation of the axis squareness, reversal spike, and backlash. The program was developed using BASIC 6.0 programming language while the material and cutting tool database were and supported with the help of ACCESS 7.0.ĭIAGNOSTIC OF CNC LATHE WITH QC 20 BALLBAR SYSTEMįull Text Available This paper presents the evaluation of the influence of the feedmotion speed on the value of selected geometric errors of CNC lathe CTX 310 eco by DMG, indentified by QC 20 Ballbar system.

The developed program made CNC part program generation process easy. By using geometric definition methods, tool path was generated and CNC part program was developed for FANUC control unit. Initially, CNC lathes turning methods and tool path development techniques were reviewed briefly. The cutting forces occurring during the turning operation have been determined for different depth of' cut, feed rate and cutting speed as well as different cutting tools and related data base has been obtained.ĬNC LATHE MACHINE PRODUCING NC CODE BY USING DIALOG METHODįull Text Available In this study, an NC code generation program utilising Dialog Method was developed for turning centres. The measurement of cutting forces exerted on the cutting tool of CNC lathe has been performed. In the present study, a BOXFORD 250 B CNC lathe has been used for experiment and optimization process. Also, failure probabilistic model of CNC lathes was analyzed by fuzzy multicriteria comprehensive evaluationĪNALYSIS OF CUTTING FORCES ON CNC LATHES EXPERIMENTAL APPROACHįull Text Available Objective of this study is to make use easy programming of CNC lathes and to achieve the optimization of part program prepared considering the limiting parameters of the machine.

The failure position and subsystem, failure mode and cause were analyzed to indicate the weak subsystem of a CNC lathe. A coding system to code failure data was devised and a failure analysis data bank of CNC lathes was established. Field failure data was collected over a period of two years on approximately 80 CNC lathes. Wang Yiqiang Jia Yazhou Yu Junyi Zheng Yuhua Yi ShangfengĪ field failure analysis of computerized numerical control ( CNC) lathes is described. International Nuclear Information System (INIS) The whole system is controlled from a PC using adequate CNC control software.įailure probabilistic model of CNC lathes This machine is composed of a ASIST mini- lathe and a two-degrees-of-freedom XZ stage designed specifically for this application. Directory of Open Access Journals (Sweden)įull Text Available This paper presents the adaptation of a mechanical mini- lathing machine to a computerized numerical control ( CNC lathing machine.
