Cutting speed formulas �Efficient cutting speed Veff = π× Deff × n/1000 (n = min-1) �When slope increasing, Deff also increasing. �Efficient diameter Deff calculation formula : Deff = (2 ap(D-ap) × α) D = ∅(Tool diameter) �Efficient cutting speed formulas : When slope ∅ is 0�Veff = π× Deff × n/1000, Deff = Efficient diameter Calculate Deff as ap with various ball endmills.
α:
α= 1 α= 1.2 α= 1.5 α= 1.7 α= 2.17 α= 2.3
Slope θ= 0� Slope θ= 7� Slope θ= 15� Slope θ= 30� Slope θ= 45� Slope θ= 60�
Graph for efficient diameter calculation (Efficient diameter graph as Ф with various ap)
Ex) When ∅6 Ball endmill’s ap is 0.3. Efficient diameter Deff becomes 2.6. Therefore, when n is 14,000 efficient cutting speed, Veff, becomes 113.7[m/min]. The graph above is relation between axial depth of 1~16∅ ball endmills and efficient diameter.
