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,
