Influence of constructive and geometric parameters of the end cutters on the microprofile characteristics of casting surfaces

The object of research is the technological route machining an aluminum alloy casting. carried out based on basic principles functionally oriented design processes in manufacture products. main hypothesis study need for a systematic approach to effect cutting modes certain method provision quality parameters system (machine – device tool workpiece). In traditional automated systems preparation production, object-oriented principle designing implemented, which provides step-by-step implementation interrelated stages prototyping algorithm without functional analysis operational characteristics product. processing functional, mating surfaces, ensuring that product performs its service purpose, must be implemented according function-oriented (FODT). A characteristic feature FOT effective compliance with accuracy and surface layer intended by designer. paper deals influence structural geometric end mills manufactured Sandvick (Sandviken, Sweden) formation microrelief casting profile during numerically controlled vertical milling center (CNC) HAAS MINIMILL (USA). An atypical option surfaces workpieces machine-building products has been applied. Its ignoring requirements manufacturer metal-cutting tools, important element workpiece), regarding use particular machine at transition machining. performance criteria were height step workpiece being processed. operating conditions have determined, make it possible establish, case deviation from manufacturer's recommendations stage rational elements system: ensure necessary characteristics.
