GENERAL RECOMMENDATIONS

SPEEDS & FEEDS are suggested starting points & may be increased or decreased depending on actual material and Machine conditions.
Reduce SFM as material hardness increases.
White chips indicate speed should be increased.
For lighter cuts use higher range of recommended SFM.
For greater radial cut use lower range of recommended SFM.
Axial depth of cut should not exceed 1-1/2 times the cutter diameter.
Extra long end mills, FPT should be reduced by 50%.
In slotting applications, SFM should be reduced by 20% of lowest range.
For Tin & TiCN coated tool – increase speed by up to 20% w/ feed rate unchanged.
For TiALN coated tools – speeds may be increased by up to 50% w/ feed rate unchanged.
