26. Describe kind of milling machine
27. A workbar with 5.0 in diameter and 48 in length is chucked in an engine lathe and supported
at the opposite end using a live center. A 40.0 in portion of the length is to be turned to a
diameter of 4.75 in one pass at a speed = 400 ft/min and a feed = 0.012 in/rev. Determine:
(a) the required depth of cut, (b) cutting time, and (c) metal removal rate.
28. The end of a large tubular workpart is to be faced on a NC vertical boring mill. The part has
an outside diameter = 45.0 in and inside diameter = 25 in. If the facing operation is
performed at a rotational speed = 30 rev/min, feed = 0.020 in/rev, and depth = 0.150 in,
determine: (a) the cutting time to complete the facing operation, (b) the cutting speeds and
metal removal rates at the beginning and end of the cut.
29. Arrange list of script to make workpart using milling machine, according to this criterion:
a. Material stock (LxWxH) : 100 x 80 x 60
b. Tools availables (unit: mm) :
- T01
: Ø 50
- T02
: Ø 40
- T03
: Ø 10
- T04
:Ø5
c. Zero point and reference point define by your self (must state)
d. Unit, mode of movement, coordinate system, spindle speed, feedrate, spindle
orientation, coolant function (if needed) please define your self.
e. Kind of material, machine specification, allowance and tollerance are ignored.
f. Calculate CSS for Ø 50 (spindle speed according to your script that you already define
before)
