FRACTIONAL & METRIC 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 Ap Ae Ae INCH Flute Length 1.5 x DC 3 x DC 2-Flute, Square, Feed Multiplier 1 0.9 Corner Radius& Ball Width/Depth Ae x DC Ap x DC Ae x DC Ap x DC Without Reach Diameter (DC) ≤0.0312 >0.0312 ≤0.0312 >0.0312 P H Profile ≤.30 ≤.50 ≤1 ≤.10 ≤.25 ≤2 K ALL M S Slot 1 ≤.20 ≤.50 1 ≤.15 ≤.35 N INCH Flute Length 1.5 x DC 3 x DC 5 x DC 8 x DC 12 x DC 3-Flute, Square, Feed Multiplier 1.35 1.22 0.65 0.33 0.2 Corner Radius& Ball Width/Depth Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Without Reach Diameter (DC) ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 P H Profile ≤.30 ≤.50 ≤1 ≤.10 ≤.25 ≤2 ≤.10 ≤.25 ≤3 ≤.05 ≤.10 ≤4 ≤.03 ≤.06 ≤6 K ALL M S Slot 1 ≤.20 ≤.50 1 ≤.15 ≤.35 1 ≤.10 ≤.20 N INCH Flute Length 1.5 x DC 3 x DC 5 x DC 8 x DC 12 x DC 4-Flute, Square, Feed Multiplier 1.57 1.41 0.59 0.59 0.36 Corner Radius& Ball Width/Depth Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Ae x DC Ap x DC Without Reach Diameter (DC) ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 ≤0.0312 >0.0312 P H Profile ≤.30 ≤.50 ≤1 ≤.10 ≤.25 ≤2 ≤.05 ≤.10 ≤3 ≤.05 ≤.10 ≤4 ≤.03 ≤.06 ≤6 K ALL M S Slot 1 ≤.20 ≤.50 1 ≤.15 ≤.35 N Flute Length 1.5 x DC 3 x DC Flute Length 1.5 x DC 3 x DC METRIC Feed Multiplier 1 0.9 METRIC Feed Multiplier 1.57 1.41 2-FluteSquare & BallWidth/Depth Ae x DC Ap x DC Ae x DC Ap x DC 4-FluteSquare & BallWidth/Depth Ae x DC Ap x DC Ae x DC Ap x DC Without Reach Diameter (DC) ≤0.0312 >0.0312 ≤0.0312 >0.0312 Without Reach Diameter (DC) ≤0.0312 >0.0312 ≤0.0312 >0.0312 P P H Profile ≤.30 ≤.50 ≤1 ≤.10 ≤.25 ≤2 H Profile ≤.30 ≤.50 ≤1 ≤.10 ≤.25 ≤2 K K ALL ALL M M S Slot 1 ≤.20 ≤.50 1 ≤.15 ≤.35 S Slot 1 ≤.20 ≤.50 1 ≤.15 ≤.35 N N 94 END MILLS wwEwN.DsgMsImLLicSrotools.com
