Calculation of the average chip thickness in relation with the ae (Radial Engagement) if ae is less than 50% of dia.
Formula: Programme Feed Rate (fz) hm = Average chip thickness Formula: Average Chip Thickness (hm)
ae = Radial engagement
fz = hm x d fz = Feed per tooth hm = fz x ae
ae d = Cutter diameter d
