Assignment: 1: Measuring and Marking Out
Measuring and Marking Out
Whilst you are in the workshop, you are required to select suitable measuring and marking out methods and equipment for three different applications. You will be making a Drill Drift, a Drill Gauge and a Tool Tray.
This means that you are expected to use your knowledge and understanding of the methods and equipment for measuring and marking out discussed in Task 1a.
During your sessions in the workshop, you will be observed working in this way. Use photos and notes in the space below
to demonstrate your skills.
YOU MUST MAKE SURE YOU GET YOUR OBSERVATION SHEET SIGNED TO ACHIEVE THIS GRADE CRITERIA.

Sheet 1
Surface plate Drill gauge, Drill Drift
Providing a large flat surface on which to place the work piece – small portable plate in workshop
Provides a datum flat surface on which to place the work piece. A scribing block or height gauge can then be used from the datum. Sometimes an angle plate is placed onto the plate.
Drill GaugeAngle plate Providing a flat surface on which to place the work piece at 90 degrees to the surface plate
Irregular shapes without flat surfaces can be clamped to the angle plate and marked out using a scribing block – Is also used to keep thin material vertical when marking out
Drill gauge, Drill Drift
Scribing Block Used for scribing lines parallel to the surface plate and transferring heights
When placed onto the surface plate, adjust the height and scribe along the work piece. Adjust to the datum and transfer height to another part of the work piece.
Drill gauge, Drill Drift, Tool tray
Steel Rule Measuring to an accuracy of 0.5 millimetres
Used for measuring on work piece or setting other tools such as height gauge

Assignment: 2 - Recommend corrective action for unsafe or defective marking out equipment
Defective Measuring and Marking Out Equipment
Reporting defective and/or unsafe equipment
During your work, marking out each of your three components, you may come across ‘defective’ equipment. What should you do with it?
• it may be defective in that it is totally un-usable
• it may be useable but inaccurate
• It may be un-safe to the user
Using a ‘Defective Equipment Report sheet’, you will produce a report for three pieces of faulty equipment stating:
• the correct name of the piece of faulty equipment
• the defect/fault (what is the problem)
• the implications of the fault if it was continued to be used
• the appropriate remedial/corrective action to make the equipment non-defective/safe

Assignment: 3 - Mark out the three different applications to the prepared work plan
For this task, you will be observed carrying out the task of marking out the three components to your work plan.
Ensure that you have the correct tools and equipment available.
You will be observed throughout the process and will be assessed on the following:
Processes: Correct processes used
Tools & Equipment: Correct tools and equipment used and used correctly
Health & Safety: Suitable H&S measures used throughout
Quality Check: That you are constantly checking you work throughout.
Time Check: You are aware of the time constraints and work within them

Assignment: 3 - Mark out the three different applications to the prepared work plan
For this task, you will be observed carrying out the task of marking out the three components to your work plan.
To gain a ‘Merit’ grade for this task, you will need to carry out appropriate checks to ensure that your marking out of the components are to the requirements of the drawings provided and that the appropriate machining and material removal techniques are considered. Again, you will be observed for this – you should ask questions about the drawings if you feel that not enough information is provided.

Unit 18: Engineering Marking Out Task: 3d Grading Criteria: D1 Key Skills:
Assignment 3: - justify the choices of datum, work-holding equipment and measurement techniques used to mark out the three different applications.
For each of the three work pieces covered in the previous tasks, you must ‘JUSTIFY’ your CHOICE of measuring and marking out
equipment.
Justify ( GIVE REASONS WHY) you decided to mark out your first ’DATUMN LINE’, the EQUIPMENT chosen (its use) and the TECHNIQUES used.
CRITICALLY EVALUATE your decisions giving good reasons and EXPLAIN these (why you chose them), say WHAT you
did, and HOW you did it.

Assignment: 4 - leaving the work area in a safe condition; cleaning of equipment; disposal of waste; storage of measuring and marking out equipment
Leaving the work area in a safe condition; cleaning of equipment; disposal of waste; storage of measuring and marking out
equipment is an important part of an engineers job.
You must give ‘SIX’ examples of where the above practice has taken place and explain the implications of NOT doing it
correctly. Use headings for each of the examples and bullet points for your examples of ‘Good Practice’. (Continue on
