ASSIGNMENT INTRODUCTION The ability to access and use information is probably one of the most critical skills required in engineering. This unit will enable learners to understand how to make effective use of textual, numeric and graphical information when working with engineering drawings, technical manuals, reference tables, specifications, charts or electronic displays, in accordance with approved procedures. Learners will consider how best to extract information from engineering drawings and related documents and also how to use drawings and related documentation to establish the work that needs to be done, carry out the work requirements and check their own work output. A good, well-documented product, is generally more useful and more successful than an excellent product that has been poorly documented. But simply creating engineering drawings and recording engineering data is insufficient. To be useful, engineering drawings and related documentation must be stored, reviewed and approved, published and maintained. Document control for engineering drawings comprises document attributes as well as a clearly defined control process.

This unit will enable learners to identify, work within and comply with appropriate organisational policies and procedures for obtaining and using the documentation that applies to given activities. It is expected that learners will be able do this with minimum supervision, taking responsibility for their own actions and the quality and accuracy of the work that they undertake.

ASSIGNMENT BRIEF

You are a recently qualified Engineer now working for a Small company that makes products for an Engineering Merchants

You have been asked to manufacture a prototype for a clamping device.

Your task is to now carefully study the drawing pack given to you with this assignment brief, then, answer the questions requiring you to extract information from the Engineering drawings and other sources in order to be able to begin to manufacture the clamping device.







1. Extracting information from the G Clamp assembly drawing, complete the parts table below by adding the part names and the quantity required for each part

2. What is the drawing number for the G Clamp assembly drawing?

………………………………………………………………………………………

3. Dimension the rectangle below to show the minimum size of material blank required in order too manufacture the G Clamp body



1. Explain why it is necessary to create two Datum edges (datum A & datum b) in order to accurately mark out the G Clamp Body.

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

2. What is the overall finished length and width of the G Clamp Body Part

………………………………………………………………………………………

3. What is the tolerance given on the length and width dimensions? Explain what this means?

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

4. Using the extract from the Zeus tapping drill chart state what is the recommended drill size for an M8 threaded hole.

………………………………………………………………………………………

Explain why the hole diameter recommended smaller than 8mm? ………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

5. Using the extract from the Zeus tapping drill chart state what is the recommended drill size for the following threaded holes.

a. M2.0 x pitch 0.25 …………………………………………………….

b. M4.0 x pitch 0.50 …………………………………………………….

c. M6.0 x pitch 1.00 …………………………………………………….

d. M10 x pitch 1.50 …………………………………………………….

6. What material should the ‘Thread Foot’ part be manufactured from?

………………………………………………………………………………………………………………………………………………………………………………

7. From the list below choose the most suitable diameter stock bar required to produce the part

10mm 15mm 25mm 19mm

8. The drawing has been drawn by the draftsman in a scale of 2:1, explain what this means.

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

9. What is the tolerance on the final external diameter of the part?

………………………………………………………………………………………

10. The drawing requests a chamfer of 1mm X 45, what does the number 45 represent?

………………………………………………………………………………………

11.Explain what is meant by the hatched lines seen in the view labelled section A-A

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

12.What do the dotted lines on the top views represent?

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………





13.What material is the part ‘Handle End’ to be manufactured from?

………………………………………………………………………………………

14.From the list below choose the most suitable diameter stock bar required to produce the part

10mm 15mm 25mm 19mm

15.What is the issue number of this drawing?

………………………………………………………………………………………

TASK TWO (M1 & D1)

Study the following images of drawings found in the Engineering Drawing workshop & identify any reasons why the product may not be able to be made using them. This may be that some important information is missing or that the drawing is damaged or has graffiti covering important dimensions

For each of the examples given, state the key issue found and a valid solution to this problem.
