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 (f )		h	= Average chip thickness	Formula: Average Chip Thickness (h	)

d f = Feed per tooth a

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

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
