Unit 2 Interpreting and Using Engineering Information - BTEC Level 2 Diploma In Engineering

Assessment - Engineering Drawings and Documentation

Part 1 You are given a drawing. The drawing's title is "Aligned Shaft, Date: 10/01/07"

The drawing shows a shaft connected to a base at the flange. This is identified as (A) on the individual drawings for each component.

i. Calculate the total height of the assembled components.
ii. Which size bolts are used to assemble the products and what is the tap drill size for it?
iii. If the shaft is made to its biggest diameter and the hole in the base is made to its smallest diameter, what clearance will there be between the shaft and the hole?

P1 Extract suitable information from engineering drawings and related documentation to enable a given task to be carried out.

Part 2 Study the two main components that make up the product shown in the drawing in Part 1. Identify any reasons why the product could not be made using this drawing. This may be because important information is missing.

Write down three reasons why the product could not be made because of missing or deficient information.

M1 Explain gaps or deficiencies in the information obtained that need to be resolved to enable a given Part to be carried out.

Part 3 Where you have found that information is missing from the drawing in Part 1, identify solutions.

i. Write down the solutions you have decided on for each missing piece of information and show how these should be marked on the drawing.

ii. The two sections of shaft at (B) need to be concentric with each other, within 0.02 mm. Show on the drawing how this geometric tolerance should be representeiv.

D1 Justify valid solutions to meet identified gaps or deficiencies with the information obtaineiv.

Part 4 The sketch of the electrical circuit drawing shown below needs to be converted into an electrical engineering drawing.

Research standard symbols used in electronic engineering, then produce a new circuit drawing using standard electronic component symbols.

P3 Select other information sources to support and check engineering drawings and related documentation.

Part 5 When you are working with drawing and documentation, you need to take good care of the documents.
i. Describe the care that must be taken when handling drawings, from removal from files to return to files.
ii. Describe the importance of safe storage of documents such as job cards.
iii. Describe some security features that may be used to protect documents in a drawing office.

M2 Specify the care and control procedures for the drawings and related documentation used when carrying out and checking own work output.
