iNC-Mill brings NC/G-code editing, 3D toolpath review, and cutting simulation to iPhone and iPad. Preview material removal for 3-axis milling and turning, inspect FANUC macros, and work with machining files locally. Cutting simulation requires an active subscription. CLOSER, CLEARER 3D TOOLPATH REVIEW • Pick two points on a toolpath to inspect 3D distance, coordinate differences, and path length, with endpoint snapping • Select a precise path position to seek playback, or navigate by move, Z change, cutting section, or tool section • Switch to a tool view and independently lock the viewing direction • Adjust X/Y/Z display scales independently to reveal small variations • Play toolpaths forward or in reverse, with speed controlled independently of play/pause • See the associated code line when available, alongside feed F and spindle S values • Customize path colors, inspect motion counts and travel-distance shares in the legend, and filter paths by playback range Measurements describe toolpath geometry. Curves use the published path segments; these are not measurements of the physical workpiece. BUILT FOR THE SHOP FLOOR • Preview stock material removal during 3-axis milling playback • 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.
