■NOTE
1) In case of side face finishing for improved productivity & efficiency, please increase ap and reduce ae. This will
also help to reduce the heat generation.
2) In case of bottom face finishing for improved productivity & efficiency, recommended to use lower (shallow) depth
of cut and increase feed speed.
B184 3) Recommend to use internal coolant supply to reduce cutting heat and built up edge problem.
