Flawless Manufacturability in Sheet Metal & CNC Machining
Prevent CAD assemblies that look perfect on screen from turning into scrap metal on the shop floor. Optimize CNC and press brake workflows before production to slash manufacturing costs, cycle times, and revision overhead.
The Costly Gap Between R&D and the Shop Floor
Unnecessarily Tight Tolerances
Overly strict tolerances (e.g., ±0.01mm) where functionally unneeded exponentially increase CNC machining and inspection costs.
With Celdor → Tolerance stack-up analysis identifies and relaxes non-critical dimensions to save money.
Incorrect Bending Radiuses
Internal bend radiuses incompatible with sheet thickness and grain direction cause cracking, severe springback, and dimensional drift.
With Celdor → Material-specific bend simulations ensure first-time-right fabrication.
Inaccessible Machining Zones
Deep pockets, sharp internal corners, and non-standard angles require expensive custom tooling or 5-axis setups for simple parts.
With Celdor → Tool accessibility is verified, modifying geometries to fit standard 3-axis end-mills.
Miscommunication with Suppliers
Ambiguous or incomplete technical drawings leave critical decisions to contract manufacturers, leading to delays and scrap.
With Celdor → A standardized 3D DFM report provides contract manufacturers with zero-ambiguity data.
Deep-Dive Analysis Across Two Critical Manufacturing Disciplines
We evaluate your parts geometrically, mechanically, and economically for both subtractive machining and sheet forming.
Sheet Metal Optimization
Bend Radius & K-Factor
Determining exact bend allowances and minimum crack-free radiuses based on specific material grades (steel, stainless, aluminum).
Hole-to-Bend Distances
Analyzing critical proximity to prevent deformation of holes, slots, and features during press brake clamping.
Corner Relief Verification
Implementing proper relief geometry at flange intersections to prevent material tearing and stacking.
Nesting & Yield Efficiency
Optimizing blank profiles and dimensions to minimize raw material waste during laser/plasma cutting.
CNC Milling & Turning Optimization
Internal Corner Radius Ratios
Balancing depth-to-radius ratios to prevent end-mill deflection, breakage, and excessively slow feed rates.
Setup Reduction & Clamping
Modifying geometry to reduce the number of machine setups, eliminating re-indexing errors and labor costs.
Deep Pockets & Wall Thickness
Identifying and reinforcing thin walls prone to severe vibration (chatter) and deflection during machining.
Thread & Tap Clearances
Ensuring adequate bottom clearance in blind holes to prevent tap binding and tool breakage.
What the DFM Report Includes
The delivered report brings together every piece of engineering data you need before committing to production.
NDA-Protected Data Review
Your single parts or assemblies (STEP, IGES, SolidWorks, etc.) are reviewed under a strict NDA — no data is ever shared with third parties.
Virtual Manufacturing Simulation
Parts are digitally simulated for tool paths, press brake bending, and cumulative tolerance stack-ups to flag high-risk geometry.
3D-Tagged Cost & Revision Report
High-cost, high-risk zones are marked with visual tags in a PDF/3D report, each paired with an actionable, lower-cost alternative.
Production-Ready Revised CAD Data
Upon your approval, finalized production data (STEP/native format) is delivered — engineered to minimize machine hours and scrap risk.
Enterprise Return on Engineering Investment
100% elimination of 'surprise' assembly interferences and expensive tooling revisions during prototype runs.
An average 30% reduction in per-part manufacturing costs by eliminating wasted CNC cycle times and custom tooling.
Empowering your procurement team with indisputable engineering data when negotiating with contract manufacturers.
Accelerating Time-to-Market by weeks through the removal of trial-and-error physical fabrication cycles.
