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 7745VT16 Technical Information Chamfering Mills Feed rate compensation: For 45° cutting, divide the hm value by the sine of the approach angle (the sine of 45° = 0,707) i.e.: hm or 0,08mm 0,707 0,707 = 0,11mm programmed feed rate 7760VT11 Technical Information Feed rate compensation: For 60° cutting, divide the hm value by the sine of the approach angle (the sine of 60° = 0,866) i.e.: hm or 0,08mm 0,866 0,866 = 0,092mm programmed feed rate A270 www.kennametal.com
