CAD Design and Engineering of Complex Machined Parts
CED Services CAD design and part engineering focuses on combining innovative creativity with function-improving design. Working with your specifications and initial ideas, our highly trained CAD/CAM software designers can work with you through a collaborative process that will begin with detailed variations of the part or prototype you have in mind—and end with realization of a working prototype or part.
CED’s 9-step CAD design process for machined parts:
1. Strategy Planning
We begin by working with you to define performance goals and important design parameters. We then brainstorm to come up with innovative ways to address any machining and design issues. This can include improving machined part appearance, improving part life, or even modifying a design as needed to avoid potential patent infringement.
2. Preliminary Modeling
Sometimes, pre-approval of a concept may be necessary, requiring a concept model to demonstrate or validate a design. Creating a preliminary model can help to clearly communicate an design direction, while ALSO providing a development structure for fitting proposed ancillary part components like gears, wires, tubes, springs, and more.
3. Concept-Approved CAD Design
With an initial design concept reviewed and approved, we deploy the latest CAD design technology to create a balanced first-pass design. Our abilities to design an aesthetically pleasing machined part is matched by our experience in engineering solutions that deliver you maximum production efficiencies.
Following our approved CAD design, we create tooling-ready CAD models that include perspective drawings, 3-D styled renderings, and cross section views as needed to better communicate structural details.
5. Prototype Development
A dimensionally accurate, functioning prototype of your part is then created using 3-D Rapid Prototype Printing or one-off CNC machining as applicable. From there, secondary and more critical design assessment can be conducted to ensure the design delivers the performance characteristics and structural integrity desired.
6. Prototype Evaluation & Refinement
Feedback from you and our designers is combined with a functional evaluation of the prototype that includes manufacturability. We then implement any warranted design improvements to arrive at a final, approved design ready for machining.
7. Design Documentation
Careful recording of the design process and final manufacturing strategy ensures repeatability and accountability. These records include a materials bill, description of process and details, elevation and 3-D CAD drawings, perspective drawings, CAD data, interior details, surface specifications, and animated video clips if necessary to illustrate crucial function.
8. Machine Tooling
Our proven expertise in complex machining and tooling ensures your design is translated into parts manufactured as efficiently and quickly as possible, while adhering to any applicable industry-mandated guidelines or requirements.
9. Quality Assurance Adjustments
Once machining of your part begins, first-run inventory is reviewed, measured, tested, and evaluated to detect any problems. We also investigate to determine is any additional cost-reduction or part enhancement is possible. Our quality commitment to you promises that we never stop looking to make your part better, faster, and for less.
