Estimate the manufacturing cost for a simple machined component: a. Compare the costs for manufacturing volumes of 1, 10, 100, 1000, and 10,000 pieces with an intermediate tolerance and surface finish. Explain why there is a great change between 1 and 10 and a small change between 1000 and 10,000 pieces. b. Compare the costs for fit, intermediate, and rough tolerances with a volume of 100 pieces. c. Compare the costs of manufacturing the component out of various materials.

- Explain How to use layers and what you can do with layers on your CAD drawing.arrow_forward8. A note in the comment section of a title block mentions that all faces should have a +.10 tolerance before heat treatment. The machinist follows the instructions but for diameters he leaves a tolerance of +.20. Why? O A. The machinist may have committed an error, and the part must be returned prior to heat treatment. OB. Diameter dimensions usually change by twice as much as the faces. OC. The tolerances for diameters aren't as critical as face tolerances. D. It's easier for the machinist to adopt MMC for diameters.arrow_forwardProblem 1: Find the average, and average deviation for the following data on the length of a pen, L. We have 5 measurements, (12.2, 12.5, 11.9,12.3, 12.2) cm. Problem 2: Find the average and the average deviation of the following measurements of a mass. (4.32, 4.35, 4.31, 4.36, 4.37, 4.34) grams.arrow_forward
- List four industries that depend on machining. How do you understand English and metric(SI) measurement systems and perform conversions between the two? List the two most common methods for measuring surface finish. what is the difference between ferrous and nonferrous metal. What is purpose of the layout? Briefly contrast the difference between drilling and reaming operations. How do you understand this class of Precision Machining Technology?arrow_forwardIn the context of our teaching and learning, which one of the below statements is mostly correct about in drawing and communication of detailed design of a component? I do not know SolidWorks well enough, so I will ask my fried to do it for me. Using a pencil and rule to show the key dimensions for the key functions and their tolerances is adequate for this course work. I do not know the SolidWorks well enough, so I must learn and use AutoCAD for drawing. I must use SolidWorks to draw the competent and for its dimensioning.arrow_forwardDescribe a use of lettering machines.arrow_forward
- In one sentence, explain the difference between straightness and flatness.arrow_forwardI need some help with this problem. On the drawing below, calculate the virtual sizes for the identified features. Remember when calculating virtual with MMC, holes appear smaller and pins appear larger. I've attached an image to go with this question.arrow_forwardWrite TRUE is the statement/s is True. If the statement is false, identify the word/s that makes the sentence incorrect and write its corresponding correct answer. 7. In planning, the tool travels along the workpiece during the removal of the material on the workpiece. 8. The factors that can be manipulated in cutting process are cutting speed, feed and depth of cut. 9.In thermally assisted machining, the tool is heated which reduces the required cutting force.arrow_forward

What flow rate (in gpm) is required to extend the press in 6 seconds?arrow_forwardSclect an appropriate manufacturing process where dimension accuracy and precisions are critical. Assume the material is aluminum alloy and the part is to be used for automotive power transmission device. Produce a manufacturing drawing with a list of tools require to manufacture the part.arrow_forwardTandem drawing of wires and tubes is necessary because; Surface finish improves after every drawing stage OIt is not possible to reduce at one stage O Annealing is needed between stages Accuracy in dimensions is not possible otherwise Which of the following abrasive materials is most appropriate for grinding nonferrous metals?
