A Visual Representation of CNC Machining.

The CNC Periodic Table of Elements is a knowledge-sharing project, designed to visually represent some of the most foundational elements of CNC machining.

Table Architecture

The table is designed to be intuitive and scannable, especially for engineers navigating multiple design and manufacturing decisions at once. It’s color-coded to group different aspects of machining into clear categories:

  • Materials: Metals and plastics commonly used in CNC machining
  • Finishes: Surface treatments and coatings applied after machining
  • Machine Types: Equipment used to produce machined parts
  • Cutting Tools: Tools that remove material during machining
  • Manufacturers: Examples of well-known CNC machine builders
  • Roles: The people involved in the machining process
  • Common Parts: Components frequently produced with CNC
  • Design Rules: Key Design for Manufacturability (DFM) guidelines

Each “element” includes a short description and often indicates whether it primarily applies to milling, turning, or both—helping users quickly connect concepts to real-world processes.
