(5:00)\nquestion 5
Answer
Explanation:
Step1: Define material - warp defects
Twist: The material is twisted along its length, like a corkscrew. A drawing could show a long - bar shaped material with a spiral pattern indicating the twist. Bow: The material curves along its length in a convex or concave shape in the plane of its width. A drawing would show a long bar with a gentle curve along its length. Cup: The material curves in a concave or convex shape across its width. A drawing could depict a rectangular piece of material with a curved surface across the width. Crook: The material has a side - to - side curve along its length. A drawing would show a long bar curving from side to side.
Step2: Answer Question 4
When cutting a board on a jointer, the concave side should face down against the jointer. This is because the convex side would not make proper contact with the flat surface of the jointer, while the concave side can be flattened out during the cutting process.
Answer:
| Material Warp (defects) | Create a drawing to represent the defect | Description of the defect |
|---|---|---|
| Twist | A long - bar with a spiral pattern | Twisted along its length |
| Bow | A long bar with a gentle length - wise curve | Curved along its length in the plane of its width |
| Cup | A rectangular piece with a curved surface across the width | Curved across its width |
| Crook | A long bar curving from side to side | Side - to - side curve along its length |
| Question 4 | The concave side should face down against the jointer. |
