Rubberfit

Rubberfit is a manufacturing operations platform built specifically for rubber-roll fabricators. It runs the cutting floor end to end: receive rolls at the dock, plan cuts with a Rust-powered nesting engine, track every offcut, ship branded customer PDFs, and keep a full audit trail behind every cut.

It is one product, one bill, one source of truth — replacing the typical stack of a CAD nesting plugin (ProNest, SigmaNEST) plus a generic MRP (Plex, Epicor, E2) plus a CRM bolt-on.

What Rubberfit is

• A real Rust nesting engine. Polygon bin packing via jagua-rs, guided local search via a sparrow-style metaheuristic. Produces optimal layouts in seconds — not generic shape arrangement.
• A full operations suite. Rolls, offcuts, jobs, customers, suppliers, POs, barcodes, notifications, audit log. Every workflow on the floor maps to one place in the app.
• Audit-ready by default. Every cut is recorded with full layout JSON. Every admin action is captured with before/after snapshots, IP, user agent.
• Operator-grade UX. Built for the floor — barcode-driven receiving, scan-to-load at the cut table, no live-load latency, no hidden state.

What Rubberfit is not

• Not a CAD plugin. Rubberfit doesn’t run inside Rhino or Fusion. It’s the operating system above the cutting machine, not the drawing tool below it.
• Not generic MRP. Rubberfit is opinionated about rubber-roll workflows. If you cut sheet metal or laminate, look elsewhere.
• Not a chatbot. No AI conversation interface. The AI capabilities (Max tier) augment the planner workflow — they don’t replace it.

Where things live

The four-step spine

Every job rides the same spine — receive, plan, cut, ship — and every step is one query away.

1. Receive. Trucks arrive. Operators scan rolls in at the dock. Length, width, durometer, and lot are captured at receipt — no manual entry. Each roll gets a barcode label printed before it leaves the receiving area.
2. Plan. Operators select parts from the queue, dial in stock, and press Pack. The Rust engine returns an optimized layout in under three seconds. Free-roam is one click away when the spec demands manual placement.
3. Cut. Layouts print to the floor as a numbered cut list. Operators tick parts off as they cut. Offcuts auto-record to offcuts with parent_roll_id lineage.
4. Ship. Finished parts roll into shipping with their barcode lineage intact. Customer PDFs auto-generate without internal artifacts — no nesting diagrams, no operator notes, no yield numbers visible to the customer.
