## What is iNC?

iNC-Mill is a local-first CNC workspace for iPhone and iPad. Edit NC/G-code, inspect 3D toolpaths, simulate FANUC macros, and watch lathe stock change during material-removal playback—without uploading machining files.

BUILT FOR THE SHOP FLOOR
• Open NC files from Files, AirDrop, or other apps
• Edit with line navigation, search, and replace
• Review very large programs in a focused read-only mode
• Inspect 3-axis and 5-axis toolpaths with rapid, feed, and arc motion clearly distinguished
• Visualize lathe stock changing as material is removed during turning playback
• Trace FANUC macro execution flow and machine state
• Organize machine and tool definitions
• Calculate feeds, speeds, scallop height, and surface-finish references
• Browse practical G/M-code reference content

LOCAL-FIRST WORKFLOW
Core editing, parsing, preview, simulation, library, and calculator workflows run on device. Your NC files do not need to be uploaded for these tools.

USE IT FOR
• Shop-floor program checks before machining
• On-site edits and troubleshooting
• Training and toolpath review
• Keeping machining references close at hand

iNC-Mill supports human review and visualization. It does not replace professional verification, collision checking, or your machine, tooling, fixture, and workplace safety procedures.

Subscriptions and free trials can be managed or canceled within your device's settings. Navigate to Settings > Apple ID > Subscriptions. It's important to cancel at least 24 hours before the end of the current period to avoid automatic renewal.

### What file formats does iNC-Mill support for NC programs?

iNC-Mill supports common NC program file formats, including .nc, .txt, and .gcode. The application is optimized for loading and browsing even very large programs, making it suitable for extensive CAM-generated files.

### Can iNC-Mill be used offline?

Yes, iNC-Mill is designed for confidential machining and works without an internet connection. Files are processed on the device, eliminating cloud dependency and ensuring usability in environments without reliable internet access.

### What are the age restrictions for iNC-Mill?

iNC-Mill has an age rating of 4+. This indicates that the content is generally suitable for all ages, with no mature themes or potentially disturbing material.

## Version history (last 5 releases)

### 1.0.11 — 2026-08-29

• New lathe material removal shows stock changing as turning programs play.
• Browse project folders more naturally, with each workspace restored where you left it.
• Each editor tab now remembers its cursor and visible position.
• Large milling programs begin showing toolpaths sooner as they load.
• FANUC macro previews now find referenced subprograms in the same folder.
• Additional stability and workflow improvements.

### 1.0.10 — 2026-06-18

This release focuses on improving CNC simulation, the file workspace, the NC editor, and the 3D toolpath preview experience.

Added FANUC macro program simulation, including session mode, batch expansion, pause, step execution, Step Over, Step Out, breakpoints, conditional breakpoints, variable inspection, call stack, and diagnostic information. Expanded programs can also be sent directly to the 3D toolpath preview for further checking.

Rebuilt the file workspace to improve local directory management, with more reliable file creation, import, move, rename, delete, and project directory state handling. More NC sample programs have also been added.

Improved NC editor performance and stability, including faster input, smoother scrolling, better syntax highlighting, and improved line number display. Fixed issues related to comment editing, IME composition input, file switching, and line navigation.

Enhanced the connection between the 3D toolpath preview and the editor, adding toolpath sync status, one-tap update, content change detection, caching, and an incremental update foundation to improve synchronization between source lines and highlighted toolpath segments.

Improved multilingual support by adding and organizing localization resources for 10 languages, covering the workspace, editor, CNC simulation, knowledge base, settings, and related interfaces.

This version also fixes issues related to UI behavior, dark mode, subscription access, tool libraries, machine kinematics, file import flow, and tab bar display, further improving overall stability.

### 1.0.9 — 2026-05-05

In this version, we’re introducing the new Quick Calculator feature. It includes basic and engineering calculation components, along with a range of convenient operations. Download and try it today.

### 1.0.8 — 2026-04-29

In this version, we introduced the all-new iNC Agent module. You can chat to get answers about CNC systems, machining processes, and CAM—powering your CNC journey. We also improved parts of the UI. Welcome to download and try it out.

### 1.0.7 — 2026-04-24

In this version, we introduced a brand-new milling calculation module with six calculators: Milling Speed Recommendation, Spindle Speed Converter, Feed Rate Converter, MRR/Power & Torque, Radial Chip Thinning, and Scallop Height/Step-over. We also fixed known issues in the NC editor module. Welcome to download and try it out.
