Que.10 _______for industrial CT scanning allow measurements even of hidden part.
- Software programs
- Flat panel X-ray detector
- Cone beam X-ray source
- X-ray line detector
✔ View Answer
Option 1: Software programs
Explanation:Some software programs for industrial CT scanning allow measurements even of hidden part.The ability of CT scanning to provide very accurate measurements of a part is used for research and development.
Que.11 Which of the following is not an advantage of ICT?
- The internal structure of the object can be obtained without destroying it.
- It is compatible with all shapes and sizes.
- Quick analysis of object materials with higher density is possible.
- Extremely accurate internal dimensions are obtained.
✔ View Answer
Option 3: Quick analysis of object materials with higher density is possible.
Que.12 Which of the following is not a disadvantage of ICT?
- Expert handling is necessary to handle CT scan and to remove noise.
- Comparison with the reference model is not possible.
- The radiation from CT scanning may harm to machine operators.
- A potential drawback with CT imaging is the possibility of artifacts in the data.
✔ View Answer
Option 2: Comparison with the reference model is not possible.
Explanation: Read the tutorial on ICT for advantages and disadvantages in details. Link is given at the end.Que.13 ______ is a potential drawback with CT imaging.
- The possibility of artifacts in the data
- Measurement of voids
- Inability to measure thickness of wall
- Inability to detect cracks in plastic
✔ View Answer
Option 1: The possibility of artifacts in the data
Explanation:Disadvantages of ICT
1. Expert handling is necessary to handle CT scan and to remove noise.
2. X-rays take longer to pass through materials with higher density therefore the CT scan will take more time to complete.
3. The radiation from CT scanning may harm to machine operators.
4. A potential drawback with CT imaging is the possibility of artifacts in the data. An artifact is anything in the image that does not accurately reflect the true geometry in the part being inspected.
Que.14 The CT scan is very useful, in reverse engineering
- when a manufactured object is available but design of the object is not available.
- if a manufactured part is available, but not the original prints or design data.
- When the object available is very expensive so as to destroy.
- All of the above.
✔ View Answer
Option 4: All of the above.
Explanation:Sometimes is a process in which manufactured products are deconstructed to extract design information from them. Often, reverse engineering involves deconstructing individual components of larger products. Reverse engineering process enables you to determine how a part was designed so that it can be recreated.
The CT scan is very useful, when a manufactured object is available but design of the object is not available.
Using CT scanning an existing part or object is measured and then an exact copy of that object is created.
This technology is extremely useful, when a manufactured part or object is available, but not the original prints or design data.
Que.15 Industrial CT scan is a non-contact measurement method.
- True
- False
✔ View Answer
Option 1: True
