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 Answer - False
The CNC machine was created to provide accurate production parts. What does
CNC stand for? Answer - Computer Numerical Control
,On CNC equipment, the machine is following a program that tells the machine
what to do. True or False Answer - True
One of the most popular machines that Haas builds today is: Answer - 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." Answer - 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 Answer - 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? Answer -
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 Answer - False
When we say the machine is "set up," we mean: Answer - 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. Answer - 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? Answer - 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

tap the holes. True or False Answer - True
When the part is complete, what are the next steps that the operator will take?
Answer - 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 Answer - 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? Answer - 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
