## What is CNC Lathe Simulator Lite?

CNC Lathe Simulator is a software simulator of a numerical control lathe is an educational methodological development intended for basic familiarization of novice machine building specialists with the principles of programming parts turning operations using standard G-code (ISO).

The three-dimensional simulation model is based on a lathe with an inclined bed, equipped with a CNC system, a twelve-position turret head, a three-jaw chuck, a tailstock, a system for supplying lubricating and cooling liquid, and other units. The material is processed along two controlled axes.

Field of application of the software product: educational process using computer technology: laboratory lessons of students in computer classes, distance learning, demonstration support of lecture material in the group of areas of training and specialties: «Metallurgy, Engineering and Material Processing».

The main functions of the application: editing the code of control programs of a lathe, operations with control program files, setting up geometric parameters of a cutting tool, continuous/step-by-step execution of control program blocks, three-dimensional visualization of tool movements in the machine’s workspace, simplified visualization of the workpiece surface, calculation of processing modes, a brief reference guide on using G-code.

The graphics component of the software uses the OpenGL 2.0 component base. The graphical user interface of the program is implemented in English.

Limitations of the Light version: it is impossible to change the length of the workpiece, only two positions of the turret head are available.

## Key features

- G-code programming practice
- 3D simulation of lathe operations
- Control program file management
- Cutting tool parameter setup

### 1/5 — Наитупейшее

*2026-08-01*

Элементарно даже не могу написать программу с клавиатуры, только с экранной что в 10 раз медленнее и неудобнее, так же когда вставляю готовую программу из буфера обмена приложение сразу же багуется и не дает перемещаться между строчками для корректировки, короче не рабочее приложение которое потратит ваше время и нервы. Буду искать альтернативу, но рабочую!

### 2/5 — Revert

*2026-03-28*

Change the app back to how it was before

### 5/5 — Amazing

*2026-01-10*

Best for beginners.

### 3/5 — Language Support

*2026-01-07, version 3.0.5*

Please add turkish language support.

### 2/5 — บันทึกทึกไม่ได้

*2025-12-23, version 3.0.5*

บันทึกแล้วเด้งออก

### 4/5 — It’s in 2d not 3d

*2025-12-18*

In the pictures it shows it in 3d but when I try it’s in 2d

### 4/5 — Good but writing code is difficult

*2025-12-16, version 3.0.5*

Program is very good but it is very hard to write a gcode because letters and numbers are in different pages it is hard to go letters and numbers every time if you make a writing panel with all numbers, point sign “.” , and letters F G S M T X Z U R W P Q N and in the other page other letters paranthesis and etc then it will be very good I am advising my students to purchase program but they all say hard to write gcode thnx for your attention

### 4/5 — .

*2025-11-10, version 3.0.4*

ดี แต่อยากให้เพิ่มใช้toolsอื่นๆหลายๆtoolsได้ในโปรแกรมเดียว และอยากให้มีการset toolsด้วย

### 1/5 — ESKİ HALİ GERİ GELSİN!

*2025-10-26, version 3.0.4*

Yeni hali berbat olmuş

### 2/5 — App

*2025-10-18*

App Crashes to much
