AND SOLUTIONS GUARANTEE A+
✔✔On a manual milling machine, the operator does not need to be precise with the
handle movements to control the distance and the depth of each cut? True or False -
✔✔False

✔✔The CNC machine was created to provide accurate production parts. What does
CNC stand for? - ✔✔Computer Numerical Control

✔✔On CNC equipment, the machine is following a program that tells the machine what
to do. True or False - ✔✔True

✔✔One of the most popular machines that Haas builds today is: - ✔✔VF-2

✔✔The CNC machine allows modern manufacturers to repeatedly make parts that are
essentially identical. This concept is known as "component or part interchangeability." -
✔✔True

✔✔An important element of a CNC machine is that the parts made today, will be
identical to the parts made yesterday, for any one program being run in the machine.
True or False - ✔✔True

✔✔When the part being made is going to be rectangular in shape, the shape of the raw
material from which the part will be made most likely is? - ✔✔Rectangular stock

✔✔It is not important to do a quick check on the raw material for basic shape and
overall size to make sure the material is correct. True or False - ✔✔False

✔✔When we say the machine is "set up," we mean: - ✔✔The machine is prepared to
make a particular part

✔✔Once the machine is set up, and the machine knows where the vise, tools, and
workpiece are, we need a _____ to get started. - ✔✔A CNC program to be loaded into
the machine to tell the machine what to do

✔✔When it is time to get started running parts, which four items are best matched to the
correct steps? - ✔✔Load the raw material, keep it square, reference the part stop, and
tighten the vise

✔✔It is very important that the Operator watch the first part being machined. True or
False - ✔✔True

, ✔✔If the Operator hears a strange noise coming from the machine, it is recommended
to: - ✔✔Press Feed Hold and get the Supervisor

✔✔There are a variety of cutting tools used in a CNC machine. The function of the face
mill is? - ✔✔To make the top of the workpiece very flat, and prepare it for additional
machining

✔✔Another popular cutting tool for CNC machining is the Endmill. The primary function
of an Endmill is for profiling a part, or creating pockets in a part. True or False - ✔✔True

✔✔Two more cutting tools that the machinist commonly uses are the drill and the tap.
These tools often work in combination, first to drill the holes, and then to tap the holes.
True or False - ✔✔True

✔✔When the part is complete, what are the next steps that the operator will take? -
✔✔Open the doors, loosen the vise and blow the part off with the airgun

✔✔The benefit of a CNC machine comes into play in production, because we can keep
making the same part, one after the other, until we have made as many as we need.
True or False - ✔✔True

✔✔When the first part is completed, the Operator needs to load the next blank into the
vise. What are the steps the Operator will take? - ✔✔The Operator loads the next blank,
makes sure it is correctly seated in the vise, tightens the vise, closes the machine
doors, and then hits Cycle Start

✔✔The basic milling machine is capable of moving in how many directions? - ✔✔3
directions or axes

✔✔When the machine moves, we describe the machine as moving in a specific axis.
What direction is the X-axis movement? - ✔✔Side to side

✔✔The Machine Coordinate System defines where the axes can move, and how far
they have moved. True or False - ✔✔True

✔✔The 3 axes are X, Y, and Z. When all 3 axes are at 0.000 in the Machine Coordinate
System, we call that position: - ✔✔The Home Position

✔✔When the table is positioned with both X and Y axes at the Zero position, table
movement in either the X or the Y axis is in the positive direction. True or False -
✔✔False
