Determine the Machining Time in Milling Operation

An HSS slab mill of 100 mm diameter and 150 mm width is used on a Horizontal milling machine to mill C50 steel. The milling cutter has 8 teeth. Determine the machining time assuming that the entire stock can be removed in one depth of 2 mm. The cutting speed V = 20 m/min and feed rate f = 0.13 mm/tooth. The cut length = 150 mm.

Solution

Given  Z = 8

D = 100 mm

d = 2 mm

V = 20 m/min

f = 0.13 mm/tooth

Approach distance   A =

Spindle speed

N = (1000 × 20) / (π× 100 )= 63.66 ≅ 65 rev/min

Time for machining t = (l + 2 × A)/ f z n = (150 + 2 × 14) / (0.13 × 8 × 65)

                                   = 2.633 min.
