The design process

In this chapter we describe the steps of the development process. Mentioning all the necessary steps, how to come to a first time right proto part.
We will take the V-model as methodology to use.

Concept of Operations:

During this phase all the high level specifications are described. These specifications form the basis for the ultimate design.
   It is important to properly discuss these specifications with the relevant stakeholders till everything is clear.

Requirements & Architecture:

During this phase the high level specifications are translate to sub-specifications where some different designers can start with translating them to a concept design.
  It is important to properly discuss these specifications with the relevant stakeholders before starting to create a concept design.

Detailed Design:

During this phase the designer is busy with solving al the deferent detail solutions within his design. Also he has to translate al the deferent constrains of al chosen manufacturing processes into his design.
    It is important to properly discuss all the design details in a critical design review.

Implementation:

During this phase the first parts have to be made by the chosen supplier. Producing will take place after a properly review of all the delivered files.
   It is important to properly check and discuss all the parts before accepting products. First parts have to be measured completely to understand the complete quality.

Integration, Test & Verification:

During this phase the individual parts have to put together and the assembly have to be tested by using the already defined test specifications.
  It is important to properly check the outcome of all the testing and agree about the results.

System Verification & Validation

During this phase the complete machine is build-up and all machine tests can be performed.

  It is important to properly check the outcome of all the testing and agree about the results.

Operation & Maintenance

During this phase all the necessary steps must be done to come to release for volume (R4V) for the complete machine.

  It is important to properly check all the steps with all different apartments.

 


The overview below you can see all detail steps how to come to a manufactured mono-part.

Specification

During this phase all the high level specifications are described. These specifications form the basis for the ultimate design.

It is important to properly discuss these specifications with the relevant stakeholders till everything is clear.

Design

Concept

During this phase the designer will make a concept model with computer aided design (CAD) software  to come to the first expression of a possible solution. Taken in account all the specifications written down in the previous phase.
It is important to properly discuss the concept, with all stakeholders, before going to the next phase. All constrains (manufacturing, cost, tooling, measuring, design) can be examined. The CAD model can be used as a common shared document.

Detail

During this phase the designer will implement in the CAD model all feedback obtained by all stakeholders.

Dimensions

During this phase the designer will add manufacturing content onto the CAD model. Nowadays it is customary to link this directly to the virtual CAD model.

Geometric DfX

With the use of DXF software manufacturing simulation, based on the CAD model can be performed. Validating the 3D CAD models for various downstream issues related to manufacturing, cost, quality, supplier capability, assembly, serviceability and environment right at the design stage.

Proto

Although nowadays more and more virtual validation is performed, creating a physical proto part still gives added value. Some physical testing can only be performed on real parts.

Production

If the design is complete validated then it can be released for series production.
