The cutting conditions above are a guide. Actual conditions will need to be adjusted according to machine rigidity, work clamp rigidity, depth of cut and other factors.
For DNHS Type, insert heights are alternatively placed, so the actual feed rate per tooth is double. Use with f z = 0. 5 mm/t (actual feed rate 1.0 mm/t) as the upper limit. The cutting conditions above are a guide. Actual conditions will need to be adjusted according to machine rigidity, work clamp rigidity, depth of cut and other factors.
