Abstract
Si possono impiegare utensili da taglio più grandi che hanno una resistenza intrinsecamente più grande per formare delle scanalature di montaggio per palette di rotore ad entrata laterale in cui la strozzatura nel punto più in basso della scanalatura viene aumentata di larghezza nel procedimento di lavorazione a macchina. La larghezza più grande lascia un intervallo su entrambi i lati della strozzatura più in basso della radice in una posizione lontana dalle superfici di sopporto del carico.
