Abstract: The right choice of cutting date and the reducing time of NC-program processing are some of the main focus by production optimization. This work presents several methods for cutting data input into the NC-program. The optimal cutting parameters have been selected from a data base after specification of cutting tools and operations. This data base contains not only catalogue information but also the process parameters obtained within production.

3. Karakostopulo О., Marina Mrkonjić, Möglichkeiten der heutigen CAM Systeme (CATIA V5) als Mittel in der Arbeitsvorbereitung, wissenschaftliche Konferenz „Innovationen und Wettbewerbsfähigkeit“, – 25. November 2011, Sofia, Bulgaria

Abstrakt. Durch Unterstützung der CAD/CAM-Systeme wird die NC-Arbeitsvorbereitung optimiert und somit die Durchlaufzeiten und die Fertigungskosten reduziert. Der Artikel beschreibt die Rolle der CAM-Systeme in der Fertigung und die Vorteile des in CATIA V5 integrierten CAM-Tools zur NC-Programmierung. Die Funktionen des CAM-Tools bei der Werkstückfertigungs-, Werkzeug- und Werkmaschinensimulation, sowie Postprocessing werden beschrieben. Anschließend werden Möglichkeiten und Grenzen, sowie Handhabung des CAM-Tools ausgewertet.

Abstract: The use of statistical methods is a way to ensure a production process with minimum rejects. The paper presents process capability index and process performance index and how they are used for monitoring of  technology processes. The use of quality assurance software to ensure quality is present.

Abstract: This work presents the more commend potential failures of process by small serial manufacturing and propose for them defection. The stages by manufacture from inquiry to transport are described. As result is Process FMEA generated including the based potential failures, cause and necessary measures for defection. This Process FMEA can be used for all parts in the company and for comparing differently production processes.
