FIG.01 Drawing → release-gated program

Drawing in.
G-code out.
With evidence.

CNCFlow AI turns DXF, PNG and PDF drawings into FANUC or GRBL programs. Deterministic CAM writes every line, a strict interpreter checks the exact bytes against your machine, stock and tool, and download unlocks only when they pass.

( 01 ) The principle

The AI never touches your G-code.

  1. ( 01 )

    Deterministic CAM generates every line. A strict interpreter re-reads the exact bytes it would hand to your controller. The language model only reviews, and its opinion can never change the release verdict.

  2. ( 02 )

    A program becomes eligible for download only when its final validation passes, and that verdict is bound to the program's SHA-256. Anything unknown, stale or malformed fails closed.

( 02 ) The challenge

Why small shops still hand-write G-code.

( CHALLENGE 01 )

CAM is built for CAM engineers.

Full CAM suites take weeks to learn and a seat licence to run. A bracket plate should not need a training course.

( CHALLENGE 02 )

Hand-edited code has no witness.

A typo in a Z value, a forgotten G43, a wrong work offset. Nothing checks the file that actually reaches the controller.

( CHALLENGE 03 )

‘Looks right’ is not evidence.

A toolpath preview shows intent. It does not prove the final bytes respect your stock, clearance plane or spindle limits.

( 03 ) The pipeline

From drawing to release-gated program.

CNCFlow AI owns everything between the drawing and the controller: geometry, toolpaths, posts, validation and evidence.

( 04 ) Release gate

What the gate checks on the exact bytes.

Not the toolpath plan. Not the preview. The program you would download, parsed line by line by a stateful interpreter that fails closed.

01

Modal state

Units, G90 and feed mode set before any motion.
MS-01 · EZ-VAL
02

Spindle & program end

M03 before a cut, M05 and M30 to finish.
SP-02 · EZ-VAL
03

Feed & spindle limits

At or below the machine profile maximum.
LM-03 · EZ-VAL
04

Tool registers

T, H and D agree; G43 and G41/G42 are consistent.
TR-04 · EZ-VAL
05

Canned cycles

G81/G83 parameters complete and sane.
CC-05 · EZ-VAL
06

Clearance plane

No XY rapid below safe Z.
CL-06 · EZ-VAL
07

Work offset & Z datum

G54–G59 and the chosen Z0 applied consistently.
WO-07 · EZ-VAL
08

Depth vs stock

Cut depth and swept extents stay inside the stock.
ST-08 · EZ-VAL
09

Arc geometry

I/J/R values describe a real arc.
AR-09 · EZ-VAL
10

Provenance

Generator, catalog version and SHA-256 all match.
PV-10 · EZ-VAL
Not checked

Clamp or fixture collisions · Tool-holder collisions · Machine-coordinate travel limits · Physical offset values

Scope

Software-qualified for generic FANUC and GRBL 2D programs. Not a substitute for a first-article dry run.

( 05 ) The workbench

See it before you cut it.

Operation review, a 3D toolpath viewer and a material-removal simulation, all in the browser. Diagnostic tools that explain the verdict without ever changing it.

Book a demo
WB-01
Operation review
Know what will be cut.
Layer-aware classification into contour, pocket and drill. Override depth and tool per operation before anything is generated.
WB-02
3D toolpath viewer
Every move, colour-coded.
Rapids, cuts and arcs by operation, depth or feed. Click a finding and the offending G-code lines light up.
WB-03
Material-removal simulation
Watch the stock disappear.
Real-time heightmap simulation in the browser with feed-proportional playback. Diagnostic only: it never changes the verdict.

( 06 ) The team

Two founders, one rule: evidence first.

We build the pipeline we would trust with our own machines. Every claim on this page is backed by the validator's code, its tests and its documented limits.
