Abstract

The article deals with the design of new technology for the treatment of thinwalled house for carrier pipe conveyor drive roller. Production on conventional machine tool is unsatisfactory because of the failure of the machine tool and the actual production inaccuracies. Conventional machine tools are being replaced by numerically controlled machines CNC OS which allow reuse through production and higher labor productivity. They were designed and compared the new CNC axes of different structures, appropriate tools, optimum cutting data. Were selected following CNC OS, three-axis horizontal machining center Pinnacle LH 500 A three-axis horizontal machining center Pinnacle LH 500 B with the added fourth axis and 5 - axis machining center Hermle C400. It was also made economic and performance evaluation of all alternatives. [ABSTRACT FROM AUTHOR]

2. The Fault Diagnostic Method of Numerical Controlled Machine Based on Sugeno Fuzzy Model.

Author

SONG Gang and HU De-jin

Abstract

During the process of fault diagnosis for computer numerically controlled (CNC) machine, the diagnostic rules describing the fault symptom are all diagnostic expert's experience. They are much random. This paper uses the Sugeno fuzzy model for fault auto diagnosis of CNC machine, and realizes fuzzy synthesis of different diagnostic expert's diagnostic conclusion. Sugeno model can eliminate random properties of expert's diagnostic conclusion and assure the accuracy of diagnostic conclusion. The method can be used to realize auto diagnosis of CNC machine based on diagnostic expert system, and the diagnostic conclusion is accurate and reliable. [ABSTRACT FROM AUTHOR]

Abstract

Baigiamajame darbe projektuojamos ir tiriamos skaitmeninio programinio valdymo frezavimo staklės (SPV). Darbe pateikta SPV staklių konstrukcijos literatūros apžvalga. Išanalizuoti pagrindiniai staklių konstrukciniai elementai ir naudojamų pavarų valdymas. Projektuojamoje dalyje, pasirinkta staklių konstrukcija. Parengta techninė užduotis, projekto algoritmas. Apskaičiuota suklio reikalinga galia. Atlikti skaičiavimai Y ašies pavarai parinkti. Atlikta suklio poslinkių įvertinimas baigtinių elementų metodu, apkrovus jas pastovia jėga. sudaryta principinė staklių ŽEV valdymo schema. Pagamintas prototipas SPV staklių, su kuriuo tiriamojoje dalyje atlikti tyrimai ašių , X Y, Z pozicionavimo paklaidoms nustatyti. Išmatuoti virpesiai tvirtinimo stalo X ašies kryptimi, nustatyta judesio dinamika. Nustatytas tvirtinimo stalo pavaros sraigto, laisvojo galo radialinis mušimas. Ištirta ŽEV valdymo signalas. Atlikus tyrimus, pagal matavimus įvertinta pagamintų staklių būklė, padarytos išvados., This final project presents a design and analysis of a 3-axis numerically controlled milling machine (CNC). The thesis also includes literature review of CNC milling machine construction. The main machine construction elements and gear management have been analyzed. The design part chooses construction type of the machine. The technical task has been completed and the algorithm of the project has been created. The power needed to the spindle has been calculated. The right gear of the Y-axis has been determined. The deformation of framesupporting columns has been evaluated using the method of finite elements, by loading them with constant force. A fundamental controller scheme for a stepper motor has been created. A prototype for CNC milling machine has been made and used to determine positioning errors of X, Y, and Z axis. Vibrations towards the X axis of the table have been measured; motion dynamics have been determined. The radial run-out of the table gear's lead screws open end has been determined. The controlling signal of the stepper motor has been analyzed. After the analysis, the machine condition has been evaluated and conclusions have been drawn using the measurements.
