Tooling U Test 1 Questions and Answers Already Passed 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 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? 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? It increases safety. What is the difference between the R method and the I and K method of programming arc motions? 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? 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 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? 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? Tool orientation and programmed path Why do most cutting operations on the lathe begin with a facing cut? 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? Tangent Which of the following do standards dictate? Standards dictate the: Language used by CNC machines and part programs. What does a T code communicate? Which tool to use Which word in a part program communicates the feed of a cutting operation? F code What component of a part program combines an address letter and a number? Word What is the function of a G code? A G code: Describes a toolpath's cutting operation. Which of the following is true about computer-aided manufacturing (CAM)? CAM: Asks the programmer a series of questions to create a program. Which of the following is the series of movements made by a single cutting tool? Toolpath What word in a part program tells the machine where to perform a cutting operation? X code What does an N code communicate? Block Number When creating a part program, which of the following should the programmer do before recording the sequence of cutting operations? Determine Program Zero What term describes the sequence of commands necessary to machine a part? Part Program Which of the following refers to the use of computers to create scale-model drawings of parts? Computer-aided design (CAD) What standard allows CAD data to be translated back and forth between different vendors' CAD systems? Initial Graphics Exchange Specifications
