Engineering Support & DFM Services
Fix It on Paper.
Not on the Floor.
The most expensive place to discover a manufacturability problem is during first article inspection — or worse, at your incoming dock. Delta's engineering team reviews every new program drawing before production begins, identifying features that will drive cost, risk dimensional conformance, or complicate inspection — and providing concrete recommendations to your engineering team before a single part is made.
This DFM collaboration is not a sales pitch — it's a genuine engineering service included with every new program at Delta. Our machinists and programmers have decades of experience across aerospace, defense, and industrial OEM programs, and they bring that knowledge to your part before the clock starts on your program. The result is fewer surprises, better parts, and lower unit costs — all backed by our AS9100 Rev D quality system.

Engineering that Pays
for Itself on Part One
Delta's DFM review is a structured engineering analysis of your drawing against our manufacturing capabilities, tooling constraints, and AS9100 quality system requirements. Every review examines:
- Tolerance stack analysis: Identifying GD&T callouts that are tighter than the manufacturing process can reliably hold — and recommending relaxation where function permits
- Feature accessibility: Spotting deep pockets, undercuts, and thin walls that require special tooling or drive up cycle time — with alternatives suggested where possible
- Process selection: Recommending the right machining process — milling, turning, multi-axis — for each feature based on geometry and tolerance
- Inspection planning: (NEED NEW DESCRIPTION) Identifying features that require CMM verification and flagging any that are ambiguously dimensioned or will be difficult to measure to print
- Material and finishing review: Confirming specified material is appropriate for the application and that finish requirements are achievable with our approved processor network
DFM review doesn't slow your program down. The time investment pays back immediately: cleaner first articles, fewer non-conformances, and lower per-unit production cost across the life of the program.
