Sheet Metal & CNC Design
Parts designed specifically for sheet metal forming and CNC machining
Designed for the machine — not just the screen.
What This Service
Actually Covers
Sheet metal and CNC machining are two of the most cost-effective manufacturing processes for custom hardware — when parts are designed correctly for the process. We design sheet metal components using the K-factor bending model, DFM rules for laser cutting and press braking, and CNC parts with correct stock allowances, cutter accessibility, and fixturing considerations.

Thread design and hardware insertion specification
How We Approach
This Service
A clear, structured methodology tailored specifically to this engagement.
Process Selection & Constraints
Confirm manufacturing process, supplier capabilities, material, and cost targets before modelling begins.
DFM-Led 3D Modelling
Model parts with DFM rules embedded — correct bend radii, CNC tool access, draft angles, and hardware inserts.
Flat Pattern & CAM Preparation
Generate flat patterns, DXFs for laser cutting, or toolpaths for CNC, and verify against supplier capabilities.
Prototype & Production Handover
Order and inspect prototypes, document any changes, and prepare the complete production drawing set.
Ideal For
Products requiring custom sheet metal chassis, brackets, mounting plates, or CNC-machined structural or aesthetic components.
What You Receive
CAD models, flat pattern DXFs, CNC toolpath files, 2D drawings, and process/finish specifications.
Often Combined With
These services frequently complement Sheet Metal & CNC Design in the same project.
