Exam Questions and CORRECT Answers
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 - CORRECT 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? - CORRECT 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? - CORRECT ANSWER✔✔- It increases
safety.
What is the difference between the R method and the I and K method of programming arc
motions? - CORRECT 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? - CORRECT
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 -
CORRECT 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? - CORRECT 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
