## What is G Code Generator CNC OD ID?

A handy tool to generate CNC G codes with just a few number inputs. It works with different OD and ID machining scenarios: 

OD:
- OD Angle into Radius, 
- OD Radius into Angle, 
- Angle to Angle Compensation, 
- OD Chamfer, 
- OD Radius, 
- OD into Radius to Step

ID:
- ID Angle into Radius,
- ID Radius into Angle CW,
- ID Radius into Angle CCW,
- ID Chamfer
- ID Radius into Shoulder,
- ID Radius

User can choose to copy and paste generated G codes to clipboard or email the G codes or save a screenshot by simply tapping a button.

## Key features

- Generate G-codes for OD machining
- Generate G-codes for ID machining
- Input numerical values for calculations
- Supports angle and radius conversions
- Handles chamfer and step operations
- Copy G-codes to clipboard
- Email generated G-codes

### 1/5 — Limited to only the 3-D models you see

*2024-09-06*

This does not generate generic g-code for anything you want to create; it only generates code for the objects shown in the app thumbnail. Granted, it would be a lifesaver if you needed code to mill or turn the objects shown. But, if you need code for something else (e.g., a laser cutter), this isn’t the app you can use for that.

### 1/5 — Неверные рассчеты

*2023-04-12*

Автор исправляй рассчеты, по формулам не сходится абсолютно никак, не вводи людей в заблуждение

### 4/5 — Could be better

*2022-05-21*

Works good but would be better if developer would’ve had radius to angle to radius option

### 5/5 — Works great!

*2022-01-02*

Please add threading cycle next!

### 1/5 — Useless for anyone with more than a grade-school education

*2021-11-02*

If you know how a G03/G02 works this app is 100% useless. It “generates” GCode for angles and radius. If you cant do that without an app you have no business writing code.

### 1/5 — Poor app

*2021-09-27*

App is so poor can’t change way of chamfer not recommend

### 5/5 — Absolutely worth it. Best $4 I ever spent

*2020-12-20*

I really really like the app I do wish that there was a OD “radius into angle into radius” It’s capable of doing this but there 2 separate functions I think there should be a option that you can do both in the same section. Also would like it on the ID as  well. But you can make it work iv had to program stuff for the ID using the OD function and then flop the numbers but hey it’s way easier then figuring it all out by hand. Wish I woulda had this 10 years ago. Very well done and would definitely spend the money on it again and again. Well worth it.

### 1/5 — Diese App erfühlt nicht seine Funktion

*2020-11-03*

Diese App erfühl nicht seine Funktion ...

### 5/5 — Turning

*2020-09-03*

Добавьте обработку канавок под резьбы, внутренние и наружние. Ну и обработку самой резьбы тоже было бы не плохо иметь. Ещё прошу добавить обработку винтовых канавок.

### 1/5 — No communication  with cnc

*2020-06-04*

It doesn’t talk with cnc other then sending the gcode to an email. Waste of money

## Frequently asked questions about G Code Generator CNC OD ID

### What does the G Code Generator CNC OD ID app do?

This app is a utility tool designed to generate CNC G-codes for both Outer Diameter (OD) and Inner Diameter (ID) machining scenarios. Users input numerical values for specific operations like angles, radii, and chamfers, and the app produces the corresponding G-code.

### What types of machining operations can this app generate G-codes for?

The app supports a variety of OD operations including angle into radius, radius into angle, angle compensation, chamfers, and radius into step. For ID operations, it covers angle into radius, radius into angle (clockwise and counter-clockwise), chamfers, radius into shoulder, and basic radius operations.

### Is this app free to use?

Yes, based on the provided information, the app is available for free. There are no mentions of in-app purchases or advertisements, suggesting a completely free user experience.

### How can I use the generated G-codes?

Once the G-codes are generated, you have several convenient options. You can directly copy the code to your clipboard for pasting into your CNC machine's programming interface, email the codes to yourself or colleagues, or save a screenshot of the generated code for documentation purposes.

### Who would benefit from using this app?

This app is ideal for machinists, CNC operators, and engineers who frequently work with CNC machines. It's particularly useful for those who need to quickly calculate and generate G-codes for common turning operations without complex manual programming.
