Turning calculator
Enter the diameter, cutting speed and feed you find in the insert data sheet: we give you spindle speed, machine feed, pass time and theoretical roughness.

Formulas: n = 1000·Vc / (π·D) · Vf = n·fn · t = L / Vf · Q = Vc·ap·fn · Ra ≈ fn² / (32·RE) (theoretical value; actual roughness depends on machine, wear and material). Start from the average Vc given in the insert data sheet and adjust according to wear.
