Once the overall design is determined, the Accudyne team begins to aggressively spec out integral components. For each particular component this specification process includes research of the various types of those components and the vendors that supply them. This research may consist of assembling information about past experience with a product or vendor, collecting input from others who have experience with the product or vendor, comparing product literature, discussing components with vendor personnel, or visiting sites. Other selection criteria are lead time, pricing, and interaction with other components.

Using these chosen parts, the engineers design the skeleton of the equipment. The CAD designers then create preliminary drawings of the mechanical, electrical and pneumatic systems.

For the preliminary design, a parametric Autodesk Inventor Professional 2012, mechanical desktop model is developed that models all functions of the innovative, engineering solution.From these drawings, a parametric AutoCAD/Mechanical Desktop model is developed to model the functions of the engineered solution and check for component interactions.

By this stage a comprehensive design notebook has been assembled. It contains everything from initial concepts to cut sheets for individual components.

In a rigorous design review at the end of this stage, the customer and Accudyne engineers review all aspects of the proposed design. Concerns are quickly and efficiently addressed to prepare for the detailed design phase.
