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

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
