NC.js is the Web interface for the Digital Thread. This provides a rich REST API for process and models as well as a matching client that displays the 3D part models for the machining workpiece, tools, CNC, as well as removal simulation, PMI annotations, MTConnect positional data, QIF face status, and other aspects of a Digital Twin on the Digital Thread.
This software uses Javascript under the Apache license, so that you can customize the client and REST API as desired. On the server, the REST API uses the STEPNode native Node.js wrapper for the STEP Tools commercial technology stack, which handles STEP and STEP-NC read/write, analysis, geometry manipulation, and material removal simulation.
