Determine the machining time for plain milling a rectangular surface of length 100 mm and
width 50 mm by a helical fluted plain HSS milling cutter of diameter 50 mm,
length 75 mm and 10 teeth. Assume A = O = 5 mm, VC = 40 m/min and so = 0.1
mm/tooth.
H.W.
The face milling cutter of D= 200 mm used to cut a block which is 200 mm = H, 1=480 mm, if f=
0.7 mm/rev is used and the overrun of the cutter is 12 mm and cutting speed 320 mm/min. Calculate
the machining time.
thickness is HW3.A block of steel has a length L-600mm and a width W-450mm. The
Machined 10mm, once by Peripheral Milling and once by planing Machine.Calculate
:Machining time for each operation if you know the following
For peripheral milling: cutting speed V =80 m/min, Feed f-0.15mm/rev, the cutter .1
diameter D =50 mm with five teeth and depth of cut d =3mm
For planing: clearance on both sides
c =25mm, cutting speed V =36.56 m/min, retum to .2
cutting ratio m =0.25, feed f=5 mm/stroke and depth of cut d =5 mm
.Calculate Material removal rate in both processes .3

- Nonearrow_forwardWhats the answer for this please ?arrow_forwardAn end milling operation is carried out along a straight line path that is 325 mm long. The cut is in a direction parallel to the x‑axis on a CNC machining center. Cutting speed = 30 m/min, and chip load = 0.06 mm. The end milling cutter has two teeth and its diameter = 16.0 mm. The x‑axis uses a DC servomotor connected directly to a leadscrew whose pitch = 6.0 mm. The optical encoder emits 400 pulses per revolution of the screw. Determine (a) feed rate during the cut, (b) rotational speed of the motor, and (c) pulse rate of the encoder at the feed rate indicated.arrow_forward
