For other groups, adjust the cutting depth according to the cutting depth factors in the above table. ^(2) When performing cutting where cutting chips may cause clogging, such as for rib cutting, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value. ^(3) Adjust by setting ae to (5 or less)x(ap)x(cutting depth ratio). When performing finishing cutting, calculate the theoretical cusp height...
