This topic covers orthogonal drawing techniques and drawing standard. Particular attention is given to examples of dimensioned assembly drawings and methods of representing threads and threaded components.
- The purpose of assembly drawings
- The types of assembly drawings
- Visualizing the shape and proportions of an object when viewing assembly drawings
- The ability to make a freehand sketch of an object using a pictorial to accurate scaled size and dimension
- Apply AS1100 drawing standards
- The AS1100 rules that apply with screw thread representation
- Representing a threaded rod/bolt
- Representing a threaded hole/nut
- Sectioning threaded components
- Describe the purpose of an assembly drawing.
- Name examples of where assembly drawings are likely to be used.
- Can assembly drawings be either orthogonal or pictorial?
- Do the rules of projection apply with assembly drawings?
- Why are threads represented rather than drawn exactly as they appear?
- Discuss the use of ‘line types’ to represent features of a V thread
- Discuss terms used for parts of a thread:
- thread depth
- V and Square
- M for Metric
- How is the length of a bolt determined?
- How is a hexagon drawn?
- What is measured to determine the diameter of a bolt?
- What size are washers?
- What is a run-out?
- What s a tap and die?
- How is a thread correctly labelled using AS1100 standards?
- Do you section threaded parts?
