Work material Sf(1) ap is shown as the criteria for Group 1 workpieces. 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. Sf(3) Adjust by setting ae to (3 to 5)x(ap)x(cutting depth ratio). When performing finishing processing, calculate the theoretical...
