SCHEMATIC DIAGRAM

 

  1. The Indicated speeds and feeds are
  • For side milling with 2‐fluted end mill to a depth=0.1xD and a width of cut=1.5xD
  • For milling with 4‐fluted, the feed should be twice that listed above.
  • For finishing operations, the feed should be increased by 30â€?0%. 3.Use a rigid and precise machine and holder.
  • Use suitable cutting fluids
