Tooling U Test 1 Questions with All Correct Answers (1) 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 is the function of a G code? A G code: - Answer-Describes a toolpath's cutting operation. Which of the following is true about computer-aided manufacturing (CAM)? CAM: - Answer-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? - Answer-Toolpath What word in a part program tells the machine where to perform a cutting operation? - Answer-X code What does an N code communicate? - Answer-Block Number When creating a part program, which of the following should the programmer do before recording the sequence of cutting operations? - Answer-Determine Program Zero What term describes the sequence of commands necessary to machine a part? - Answer-Part Program Which of the following refers to the use of computers to create scale-model drawings of parts? - Answer-Computer-aided design (CAD) What standard allows CAD data to be translated back and forth between different vendors' CAD systems? - Answer-Initial Graphics Exchange Specifications (IGES) In what form are toolpath instructions input into the CNC machine? Toolpath instructions are input into the CNC machine as a: - Answer-Part program 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
