1) The entered values apply for a chipping depth of up to 2.24 mm. From 2.24 mm to 7.1 mm the values must be reduced by 1 stage of the row R10 by approximately 20%. From 7.1 mm to 22.4
mm the values must be reduced by 1 stage of the row R5 by approximately 40%.
2) The values v must be reduced by 30 .... to 50% for turning a crust, for removal of cast skin or for sand inclusions.
