Estimate the Cutting Time
A surface 115 mm wide and 250 mm long is to be rough milled with a depth of cut of 6 mm by a 16-tooth cemented carbide face mill 150 mm in diameter. The work material is alloy steel (200 BHN). Estimate the cutting time.
(Cutting speed = 60 m/min, f = 0.18mm/tooth).
Solution
Given: Numbers of teeth on cut, Z = 16
Diameter of cut, D = 150 mm
Depth of cut, d = 6 mm
Width of cut, W = 115 mm
Cutting speed, V = 60 m/min
Feed rate f = 0.18 mm/tooth
Spindle speed
= 127.32 ≈ 125 rev/min
Since
W = D /2,
Approach distance,
= 63.44 ≈ 65 mm.
