Plan / Diary of Manufacture

Diary of Manufacture – 2 - 3 slides

A ‘Diary of Manufacture’ means demonstrating the justification for the selection of appropriate materials and components (using your CAD parts) and proposed techniques and processes to make those parts i.e. The neck of the main product should be manufactured from an extruded Aluminium tube because the part needs to be strong yet light in weight and should be resistant to moisture and not rust. As the part will move a surface painted finish would not be appropriate however I could consider using anodised aluminium to add an aesthetic effect. the best way to control product quality. 

A diary of manufacture documents each stage of manufacture. This enables checks to be made for quality, so each component of the product is made to the same standard. A diary of manufacture also enables faults to be identified and provides feedback, so that changes can be made, if necessary.

The work that you have already done on modelling, prototyping and testing (Further Development / Concept Modelling) should help. 

Other planning decisions may involve:

• Reflecting on how easy the product was to manufacture in the time available, if it is necessary to simplify anything or if any special materials or tools are required

• How were the components manufactured – CADCAM, Hand tools / workshop 

• Estimating costs of materials, production costs and a possible selling price

Your record / diary should provide clear and detailed instructions for making your product. You should identify:

• The order of assembly of the different components

• Tools and equipment to be used

• Assembly processes

• The time each stage of manufacture / process took

• Key stages of manufacture where quality is checked (QA/QC) - FEEDBACK

• Safety requirements and/or procedures

This should be detailed, listing the planning and making of each component of your product. It is therefore vital that you record / write every step where possible. This ‘Diary of Manufacture’ can be produced using screenshots & photos (Onshape - Parts - sanded parts - sprayed (primer) parts - sprayed (final colour) parts - assembled model).
