HAAS MILL UPDATED END OF COURSE QUESTIONS AND
SOLUTIONS GUARANTEE A+
✔✔When establishing work offsets, it is important to know the exact location of the
cutting tool tip in relation to the face of the spindle. The length between the tip of the tool
and the face of the spindle is called: - ✔✔Tool coordinate or tool offset
✔✔Another useful display of coordinates is the Program Coordinate Display. The
Program Coordinate Display will treat our workpiece as our new zero starting point.
True or False - ✔✔True
✔✔The common language used to tell computerized machine tools how to make things
is: - ✔✔G-code
✔✔There are two basic types of function codes used in CNC programming. Those code
types are G and M codes. True or False - ✔✔True
✔✔G-codes tell the machine how to behave or what to do. What do the M-codes do? -
✔✔Act as switches that turn a function On or Off
✔✔Both G- and M-codes can have letter addresses in the line of code that provide
additional instructions to the machine. True or False - ✔✔True
✔✔Each line of code in the program gives the machine instructions what to do. The
combination of codes M03 S2000 simply tells the machine to start the spindle rotating in
the clockwise direction, at a speed of 2000 rpm. - ✔✔True
✔✔There are 3 basic G-codes that we mention in the video. Those 3 codes are: -
✔✔G01, G02, G03
✔✔The number 1 cause of injury in a machine shop is: - ✔✔Inattention by the Operator
✔✔There are many ways to stop a machine. The next couple of questions all focus on
the various ways to stop a machine. Which answer below best describes what the
Reset button does? - ✔✔Stops a program, and returns it to the first line of code in the
program
✔✔Which answer below best describes what the Feed Hold button does? - ✔✔Stops
axis movement, but keeps the spindle turning
✔✔Which answer below is the best description of what the Emergency Stop Button
does? - ✔✔Stops all machine motion, including the spindle rotation.
, ✔✔If anyone needs to work inside the machine enclosure, the E-Stop Button should
always be engaged. True or False - ✔✔True
✔✔If the machine looks like it is about to crash, or it has already crashed, you should: -
✔✔Immediately press the E-Stop Button
✔✔At the back of the machine is the control cabinet. This is where the majority of the
electronics for the machine are. You should NEVER open the control cabinet. - ✔✔True
✔✔The coolant tank is commonly behind or to the side of the machine. It is common to
see coolant leaks around the tank, and not anything to be concerned about. True or
False - ✔✔False
✔✔Inside the machine, you will often find an auger or a conveyor for removing chips.
Never put your hands near either of these devices. - ✔✔True
✔✔Cutting tools are razor sharp. When handling the cutting tool, you should firmly wrap
your hand around the cutting tool surface. True or False - ✔✔False
✔✔If you are leaning into the machine enclosure to check a part in the vise, never rest
your hand on the spindle head cover. If pushed, the button on the head cover will: -
✔✔Drop the tool out of the spindle; this is the tool-release button
✔✔When clamping a part into a vise, you need to be 100% sure the part is clamped
tight enough to ensure it will not come out while the machine is cutting. True or False -
✔✔True
✔✔While we recommend that you wear safety glasses at all times, it is extremely
important to have your glasses on when blowing off parts and chips in the machine.
True or False - ✔✔True
✔✔Many shops will power down the machines each night. The main circuit breaker will
commonly be left in the ON position when the machine is powered down. Where is the
main circuit breaker located on the machine? - ✔✔In the door of the control cabinet at
the rear of the machine
✔✔When starting up the Haas machine, it is important to check that the air pressure is
in the correct range. That range is 50-65 psi. True or False - ✔✔False
✔✔When it is time turn on the machine, the Operator will press the Power On button.
