Send your 3D models and 2D drawings for a comprehensive DFM review. Both files required — the STEP gives geometry, the drawing gives tolerances.
Full solid geometry. Used to review features, tool access, wall thickness, pocket ratios, undercuts, and machining setups.
Dimensions, GD&T callouts, surface finish symbols, material notes. This is where I find the real risk — over-tight tolerances on non-functional features, conflicting datums, unreachable surface finish on deep bores.
From your files to a report you can act on the same day. Four steps.
Submit your 3D models and 2D drawings for a comprehensive DFM review. Both files are required.
We analyze your designs for manufacturability, cross-referencing geometry against the drawing to flag every risk.
Receive a detailed report with numbered findings, annotated screenshots, and specific geometry changes. Not generic advice.
Many clients run us as their external DFM engineer — reviewing every new part before it goes to the shop floor.
Every review covers these six areas. The 2D drawing is what makes most of this possible.
Thin walls, deep pockets, undercuts, tool access issues, minimum radius violations — flagged with feature location from your STEP.
Over-specified tolerances, conflicting datums, unreachable surface finish on deep bores. All from your actual 2D drawing.
Datum selection, clamping approach, setup count. How many ops and where the hardest fixturing problems are.
Changes ranked by cost-reduction potential. Your engineers know what to fix first, backed by cycle time reasoning.
Different advice for 10 pcs vs 10,000 pcs. Process selection tied to your stated required quantity.
Every geometry change is checked against what you told us the part does. No simplifications that compromise function.
NNMachining is a DFM and toolshop engineering practice for manufacturers. We work as your external manufacturing engineer — reviewing designs, recommending process changes, and making sure parts are manufacturable before they hit the floor.
Every report is written by a human engineer who opened your actual files. You get specific findings with your part's feature names and drawing callout numbers.
Your IP is protected before we discuss a single feature.
Feedback within one business day, every time.
Every callout written by hand from your actual files.
STEP + 2D drawing. Without the drawing there's no real DFM.
Upload your STEP and 2D drawing. Get a numbered findings report within 24 hours.
