Guidelines for Success
  • Minimize overhang and have a rigid set-up
  • Keep cutting engagement at 1/2 to 5/8 of the cutter diameter
  • Reduce feed by 25% upon entrance and exit of the cut
  • Use air blast, do not use coolant
  • Use helical interpolation to ramp down into a cavity
  • Increase feed rates in corners to compensate for heat loss
  • Use climb milling
  • Use shrink fit holders whenever possible
  • Safety first – machine within recommended conditions
  • As DOC gets smaller, speed should increase to compensate for heat loss
  • Ajusta la velocidad para maximizar la deformación plástica
