SOLID END MILLS  1)	Supply cutting fluid sufficiently during cutting. For dry-cutting, decrease the revolution and feed rate proportionately by 20  50%.
                 2)	When the diameter exceeds 30 and the metal removal is less than the quantity shown in the table, the revolution and feed rate may be

                    increased proportionately by 10  40%.
                 3)	If the rigidity of the machine or the work materials installation is very low, or chattering and noise are generated, reduce the revolution and

                    feed rate proportionately.
