CAD drafting for sheet metal products as per DFMA guidelines reduce TAT by 56%

Once the team received input PDF drawings, it defined the scope of work and initiated developing manufacturing drawings.

• Initial calls were set up to clear off queries related to tooling capabilities and other RFIs in input drawings
• Sometimes the team would also receive SolidWorks and other CAD models to correct the design details like dimensions and other features
• Both, corrections and new drawing development were done after primary training by the design head at the client’s end to get acquainted with their drawing styles
• Based on our previous experience with DFMA guidelines we began with sheet metal modeling in SolidWorks
• Part drawings, assemblies, manufacturing drawings, BOMs were also created alongside
• Team developed 3D parametric models with a top-down approach for repetitive products. This enabled the interlinking of parts and assembles to auto-update properties and design parameters
• All work was allocated to assigned team members on a priority basis to ensure meeting delivery timelines
• A work log was maintained to address the concern of remarks while multiple engineers worked on the same work order
• The team gradually built the library of all product mixes for the client after three man-months, about 70% of the product library is readily available
• Once the final sheet metal fabrication drawings with parts and assemblies were ready, they were QC-ed against the checklist and shared with the client through secure email
• Additionally, in case of logo drawing 2D AutoCAD files were also generated and shared with the client
