Speeds and Feeds

Instructions:

  • rpm = use speed from INCH or METRIC Baseline chart
  • ipm = INCH Baseline Feed (ipm) x Feed Multiplier [from selected chart below]
  • mm/min = METRIC Baseline Feed (mm/min) x Feed Multiplier [from selected chart below]
  • Reduce speed and feed 30 percent when using uncoated tools
  • Find Width of Cut (Ae) and Depth of Cut (Ap) recommendations on chart below
  • refer to the KYOCERA SGS Tool Wizard® or sgsmicrotools.com for detailed technical charts by series

Note:

  • Bhn (Brinell) HRc (Rockwell C)
  • reduce speed and feed 30 percent when using uncoated tools
  • Fz x No. of Flutes x max available rpm when recommendation exceeds machine limit
  • helical ramp at 1 degrees or less, using slotting speed and feed rates (plunging is not recommended)
  • reduce speed and feed for materials harder than listed
  • reduce feed and Ae when finish milling (.02 x DC maximum)
