    Depth of Cut
    Recommendations and Adjustments
    -Slotting
    -

    Axial Depth of Cut = AD
    For Tool Diameters 1/8" and Under: AD=Dia. of Tool X 0.25 to 0.05. For Diameters above 1/8" AD=Dia. X .05 to 1.5

    SFM and Feed
    For AD between 0.25 to 0.5 of Tool Dia. SFM=0.8 Lowest Range Value. Feed at Suggested Value. For AD equal and above Tool Dia.
    SFM=0.8 X Highest Speed Range. Feed should be 0.5 X Suggested Value.


    Depth of Cut
    Recommendations and Adjustments
    -Profiling-

    Axial Depth of Cut = AD
    Axial Depth of Cut= 1.5 X Tool Dia.

    SFM and Feed
    For Radial Depth of Cut use 0.25 X Tool Dia. Use Higher SFM Range. For Long and Extra Carbide Reduce Feed by 50%.
