CNC tools
22 tools for the shop floor. Free with an account. The ones marked Beta are in closed beta.
G-code from drawingBetaAI
Upload the drawing and review the program the AI proposes.
Drawing to STEP 3DBetaAI
From drawing to 3D part with editable dimensions, as STEP or STL.
Process assistantBetaAI
Programming, maintenance and quality questions.
Control plansBetaAI
Dimensions and GD&T taken from the drawing, as PDF or CSV.
CNC simulator & editorAI
Edit G-code and see the toolpath in 2D and 3D.
Cycle timeAI
How long a program takes, before it goes on the machine.
Guided CNC programmingAI
Write G-code with lathe and mill examples and see it in the viewer.
Twin-spindle lathesAI
Time for both channels and the transfer routine.
Machining quote
Material, time and margin: price per part and per batch.
Cutting parameters
Vc, rpm, feed and roughness by material and operation.
CNC alarms
Cause and fix for each alarm, by control and by code.
G and M codes
What each code does and which controls support it.
Hole circle (PCD)
X/Y coordinates for holes spaced around a circle.
Machining slide rule
Move Vc, diameter or feed and watch everything change at once.
Shop trigonometry
Triangles, chamfers, tapers and polar coordinates for programming.
ISO fits
Fits like H7/g6 and deviations per ISO 286.
GD&T symbols
What each drawing symbol means and how to measure it.
Threading
Tap drill, thread identification, G76/G84 cycles and repair.
Parts per bar
How many parts you get from a bar, with parting and end trim.
Hardness converter
HRC, HB, HV and more, with a table per material family.
Materials catalog
EN, DIN, AISI and JIS equivalents, with machining data.
Thermal expansion
How much the part grows or shrinks with temperature.
Frequently asked questions
What free CNC tools does GetGCode offer?
Cutting parameter calculators (Vc), ISO fits, threading, material equivalents, GD&T symbols, G/M code list, CNC alarms guide and the automatic job quoter. The GetGCode Viewer edits and simulates G-code; AI features are part of Pro.
What does Pro / AI mean in this hub?
Features that use language models: generate G-code from a drawing, process chat, control plans from drawings, Viewer AI tips/conversion and the CNC dialect converter. The Pro AI beta is closed; sign up to receive an email when it opens.
How do I go from a calculator to the full workflow?
From the hub you can open the quoter, drawing→G-code generator or assistant. Many tools link into those products so you keep working inside GetGCode.
