The following steps are used to program a part using TNC:

  1. Program the part to finished dimensions.
  2. Approach and Departure – Ensure that there is an approach move for each compensated path and determine which direction (G41 or G42) is used. Ensure that there is also a departure move for each compensated path.
  3. Tool Nose Radius and Wear – Select a standard insert (tool with radius) to be used for each tool. Set the tool nose radius of each compensated tool. Clear the corresponding tool nose wear offset to zero for each tool.
  4. Tool Tip Direction – Input the tool tip direction for each tool that is using compensation, G41 or G42.
  5. Tool Geometry Offset – Set the tool length geometry and clear the length wear offsets of each tool.
  6. Check Compensation Geometry – Debug the program in graphics mode and correct any tool nose compensation geometry problems that may occur. A problem can be detected in two ways: an alarm is generated indicating compensation interference, or the incorrect geometry is seen generated in graphics mode.
  7. Run and Inspect First Article – Adjust compensated wear for the setup part.
