ANSWERS LATEST UPDATE 2025
What must a programmer do to calculate the X-axis location of the start of the partial arc
shown? The programmer must find the length of - ANSWER Side a, double it, and
subtract that amount from the workpiece face diameter.
A standard twist drill has a 0.50 in. (12.70 mm) diameter. What trigonometric
calculations can be used to find the accurate drill depth? - ANSWER Find the length of
the shortest side of the right triangle, side b, that is formed at the drill tip, using the ratio
tan 59°=0.25 in. (6.35mm)/a.
What is the purpose of adding an approach to a cut? - ANSWER It increases safety.
What is the difference between the R method and the I and K method of programming
arc motions? - ANSWER The R method uses the radius size, while the I and K method
uses the arc center coordinates.
What is the function of codes G41 and G42 in cutting an arc into a part? - ANSWER
They tell the control whether the tool is to the left or right of the feed direction.
What steps are necessary to find the Z axis coordinate for the end point of the partial
arc shown? To find the Z axis location for the end of the partial arc, find the length of -
ANSWER Side a, then subtract it from the arc radius.
Which of the following will correctly calculate the X axis location for the center of a
concave full arc, when using TNRC? - ANSWER Double the arc radius and add it to the
value of X at the start of the cut (X at arc center = 2 x radius + X at start).
In addition to the dimensions of the radius itself, what information must a programmer
know in order to utilize tool nose radius compensation? - ANSWER Tool orientation and
programmed path
Why do most cutting operations on the lathe begin with a facing cut? - ANSWER
Program zero is usually located on the face of the part.
Which trigonometric function of a right triangle is the side opposite the angle divided by
the side adjacent to the angle? - ANSWER Tangent
Which of the following do standards dictate? Standards dictate the: - ANSWER
Language used by CNC machines and part programs.
What does a T code communicate? - ANSWER Which tool to use
, Which word in a part program communicates the feed of a cutting operation? -
ANSWER F code
What component of a part program combines an address letter and a number? -
ANSWER Word
What CAD/CAM function creates route sheets, documents that guide and organize
steps in manufacturing parts? - ANSWER Process planning
What is the first step in the CAM process? - ANSWER Determining tools and
workholding
During what stage in the CAM process are coded machine instructions created and then
converted into machine control data specific to a CNC machine? - ANSWER Post-
processing
In modern CAD processes, parts are designed: - ANSWER Internally, using the design
abilities of the CAD software itself.
What allows designers to see how multiple parts move together? - ANSWER 3D
assembly modeling
What type of geometric model consists of planes that fit together to form a hollow
object? - ANSWER Surface model
The use of CAD/CAM reduces cycle time. Cycle time is: - ANSWER The total time from
the beginning to the end of your process
In CAD, what is a hard copy? A hard copy is: - ANSWER A physical part drawing that is
printed on paper.
What is the name of the storage method used for CAD/CAM data? - ANSWER
Database
What is the purpose of the Standard for the Exchange of Product Model Data (STEP)?
The purpose of STEP is to: - ANSWER Exchange CAD/CAM data internationally.
Which of the following is used by CNC machines to machine workpieces? - ANSWER
Part program
Which step of part program creation should happen before the part programmer
determines the sequence of cutting operations? - ANSWER Select the appropriate
machine.
