001) Explain the design process you follow when developing a new product

New product development involves several key steps. The first step is to understand the requirements and constraints. Then a few concept designs are created. Next, the concept designs are evaluated for feasibility and market potential. Once the concept design is finalized, detail design starts, which includes finalizing the geometry, dimensions, material, etc. FEA is also part of the detailed design where the strength of the product is substantiated. Once the detailed design is completed, the 2d manufacturing drawings that include the views, dimensions, tolerances, and GD&T are created. Next, a few prototypes are manufactured and tested. Then, the detailed design and manufacturing drawings are revised based on the results from testing the prototypes. Finally, the production starts, and the product is launched.

002) How do you approach design for manufacturability?

Designing for manufacturability ensures a design can be efficiently and cost-effectively manufactured. Therefore, I believe in creating a DFM guidelines document and a DFM checklist with the manufacturing and production engineers. The DFM guidelines document contains the recommended criteria for product geometry, material selection, and selection of manufacturing processes, including assembly methods, tolerances, standard parts, etc. The DFM checklist has to be filled by the designer and then cross-checked by the supervisor to ensure the designs are manufacturable.

The preferred corner radius of machined pockets is decided based on the milling cutters used in the machine shop. The wall thickness of machined pockets, fastener pitch, edge distance of holes, and preferred fastener sizes are a few more examples of DFM.
