## What is CNC VMC Simulator?

The CNC milling machine simulator is a multimedia application designed to provide a basic introduction to beginner mechanical engineering professionals with the principles of programming operations for milling parts using a standard (ISO) G-code.

The main task of the application is syntactic analysis (parsing) of the code of control programs in order to build a graphical model of cutting tool trajectories in three-dimensional space.

The main functions of the application: editing the code of the control programs of the milling machine, operations with files of control programs, setting the geometric parameters of the cutting tool, continuous/step-by-step execution of blocks of control programs, three-dimensional visualization of tool movements in the working space of the machine, simplified visualization of the machined surface of the part, calculation of processing modes, a quick reference guide to using G-code.

The main limitations of the application are: low accuracy of cutting surface modeling, the impossibility of using polygonal geometry as a workpiece, a simplified model of machine tooling elements.

## Key features

- G-code programming editor
- 3D tool path visualization
- Control program execution
- Geometric tool parameter settings
- Machined surface visualization
- G-code reference guide

### 3/5 — Request to the dev

*2026-08-08*

Very good sim, but there is a need to add more tools like slot mill, and there is no option for a second round after the first round of operation on the workpeice. Small tools are not possible. Optional M01 Switch is missing. Thank you.

### 3/5 — Its not fully finished app

*2026-06-20*

App doesn’t allow you to copy paste or open the nc file from phone folder we need to write whole long program which consumes lot of time. If developer can improve this features then it would be worth of buying paid version or else for limited use no purpose.

### 2/5 — Impossible de sauvegarder

*2026-01-27*

Bon jeu, mais impossible de sauvegarder son programme, crash au moment d’inscrire un nom

### 3/5 — Много багов

*2026-01-10*

Баги относительно текстового редактора. После работы в нем остальные функции перестают работать, вплоть до вылета приложения

### 1/5 — Buggy, unfinished

*2025-11-27*

Has an annoying bug (not sure what’s causing it) where it basically breaks the whole game, offsets don’t work, manual stops working, doesn’t let you save…. Very annoying considering I paid money for this

### 3/5 — Corrijam os bugs

*2025-06-28*

fecha sozinho, não permite colar códigos (até permite mas tem um segredo), arquivos somem depois de usar o aplicativo por alguns minutos, impossibilitando salvar ou carregar algum arquivo, seria muito melhor deixarem o teclado nativo do celular, para programar manual ou fazer alterações em programa gerado, fora isso, aplicativo excelente, melhorando o que é necessário seria nota 10.

### 1/5 — Useless

*2025-06-03*

The app does not allow you to copy paste code from outside or to open a txt file from inside the app. That means you have to manually write all the G code which makes this app useless. Waste of money, do not buy this. The Dev knows about it but they don’t do anything.

### 4/5 — Good for machinist starting out

*2025-05-29*

Everything that you can do on a mill with MDI commands you can almost do here! Really helps for people getting into machining like me to learn all i need about programming and G-codes and allowing you to experiment and visualize without potentially losing your job! But please update the app for the iphones with the dynamic island as it covers buttons and keys that i need to press having me constantly rotate the phone to access them. other than that i love it.

### 5/5 — Great Simulator..

*2025-03-30*

This simulator is a great way to learn, or improve your knowledge of program reading/writing/understanding of G and M codes, macros, etc.

### 4/5 — 強制終了します。

*2025-02-10*

サブコードを使ったプログラムをデバッグすると
Message
Array index out of bounds, Index: 5, Array Length: 4 in gcode_parser.agc at line 872
