Planning your manufacture
Before you make, make a plan...
This section is your opportunity to demonstrate that you know how your prototype is going to be manufactured in college. There is no room for guess work or bodging here.
Where to start?
Look at your final/ refined design solution and consider the following stages:
-
plan out what you need to do to manufacture it - in a simple structure (list or table)
-
break down each of the things you need to do, looking at each component individually
-
look at each component and outline what tools, equipment and materials you will need for its manufacture
-
look at any health and safety implications at each stage of manufacturing
-
Include details of any Quality assurance or quality control you will include
scroll to the bottom of section 4 (4.3)
Assessment criteria says - PLANNING
Exceptional and fully relevant, covering all requirements and safety considerations identified from the technical specification to convincingly manage the making process..
Assessment criteria says
Risk Assessments
Exceptional analysis and evaluation that result in perceptive and appropriate considerations of health and safety risks.
Be mindful of the materials, tools and equipment that are available to you - you are planning what you will use to make your prototype, not what would be used in industry for commercial manufacture.
How much time do you have?

Things you should consider:
> Stages of manufacture
> Materials
> Tools
> Equipment
> PPE
> Risk Assessments
> Quality Assurance
> Quality Control
> Wastage
> Jig/ template use
> Tolerances
> Timings
> Other help/ assistance
This is the introduction/ outline to your planning. Keep it general and outline your estimated times for manufacturing your product - stage by stage. This may well get updated as you go along as you might not stick to the times (errors/ issues do occur)
Consider breaking it down and setting it up like this (a simple gannt chart):

Once you have broken down the basics of what you need to do in order to manufacture your prototype, its time to look at the details. (depending on how much detail you went into in the table above, you might not need to use the following)

Description of activity
Now with a focus on each of the individual components its time to outline what you need to do to manufacture it, stage-by-stage/ step-by-step
Now you've outlined a general time plan for manufacture and looked at each of the parts/ components the product consists of, it's time to consider further details for each part/ component - what health & safety requirements there are at each stage and how you will ensure a high quality/ accurate component is created.

This is the next level of detail, outlining the following:
-
Material - what material you will use for each part of the component
-
tools & equipment - what tools and equipment will you need at each stage of the component manufacture. from start (marking out with a pencil) to finish (applying a finish)
-
Health &Safety implication - what are the dangers of manufacturing this part or component? Which risk assessments do you need to look at?
-
QA & QC - what are you doing at each stage to ensure there is a high quality outcome?
Quality assurance - what are you putting in place before you stare to ensure the quality and accuracy is high?
Quality control - what are you going to check along the way to ensure its being made to the highest standard?
!
To work alongside your GANTT chart, a flow diagram wroks really well to indentify the quality control measures you have put in place. Including decisions/ questions in your plan shows that you are considering the quality checks you will make alone the way to ensure your product is made with quality, within tolerance and to a high standard of safety. See this basic example.
Consider the use of and inclusion of tinkgs like this:
> Making jigs and templates
> checking measurements
> checking processes before moving onto the next stage
> checking against your drawings
> Using depth gauges/ purposeful pieces of equipment
Ensure you are working accurately and using the appropriate equipment for the job you are doing.

You could also use the following methods to support your planning:
Project management tools:
-
Critical path analysis
-
Six sigma
-
scrum
Use what is appropriate for your project and the ones you are most comfortable using
