4.1 Correctly Load And Unload Parts -
Basic Mill Operator
Cleaning the fixture or workholding device is critical. By not properly cleaning the
workholding, you run the risk of: - ANS-Putting a dent or a ding in the surface of your
next part(s), or possibly causing the workpiece to be out of position in the vise
Every workpiece in a job run needs to be located in the same position every time you
load the vise. - ANS-True
It is important to spend time in front of an actual CNC machine to become familiar with
what they do and how they operate. A good place to do this is: - ANS-Your local Haas
Factory Outlet
Once you have the new workpiece loaded into the vise, and have verified it is in the
correct position, the next step is: - ANS-While keeping an eye on the part in the vise, hit
the Cycle Start button. Keep your hands near the Feed Hold and E-Stop buttons in case
there is a problem. Watch and listen to the cutter engage with the part. If all seems OK,
you can take your hands off the keypad panel.
The best position for the Operator when blowing off the part and the workholding fixture
is: - ANS-Standing behind one of the doors while it's in the closed position, and using
only one arm and the airgun in the machine enclosure to blow off the fixture and
workpiece
The bottom of the vise locates the workpiece for which axis? - ANS-Z axis
There are 3 steps to keep in mind when blowing off the workpiece and fixture. What are
the correct 3 steps for this process? - ANS-Open the doors of the machine. First, blow
off the part in the fixture; second, remove the workpiece and blow it off; and third, open
the fixture or workholding and blow it off, to make sure there are no chips or debris on
any locating surface.
Vise jaws come in a number of different configurations. There is a straight, hard Jaw for
clamping a part that sits all the way down in the vise. We call these hard jaws because:
- ANS-They are made from hardened steel, and are more durable
