mill has to be calculated through a heat balance. The maximum admissible mill inlet temperature is < 450 [C]. Gas speeds: The mill has to be sized to meet the required speed ranges: e Nozzle ring: = 30 [m/s], higher speeds can be adjusted by covering nozzles e Mill casing: 7 [m/s] for vertical transport

When high spindle speeds were attempted in producing the slots, excessive runout and chatter caused match line problems while roughing with three cutting passes using a .75inch indexable insert end mill. By using the same end mill with a SinoT toolholder, the HMC's spindle speed could be increased from 8,000 to 14,000 revolutions per minute.
