CNC Programming

STEPS IN CNC PROCESS (Manual Programming)

  1. Review part drawing
  2. Decide which machine will produce the part
  3. Choose the tooling required
  4. Decide on the machining sequence
  5. Do math calculations to find part coordinates
  6. Calculate the spindle speeds and feed rates required for the tooling and     part material
  7. Write the CNC program
  8. Prepare setup sheets and tool lists
  9. Verify the program using a CNC simulator or the actual machine
  10. Edit the program if necessary
  11. Run the program and produce the part

STEPS IN THE CNC PROCESS (CAM)

  1. Develop the three-dimensional geometric model of the part using CAD
  2. Decide which machining operations are required to produce the part
  3. Choose the tooling to be used
  4. Run a CAM software program to generate the CNC part program, including the setup sheets and list of tools
  5. Verify the program on a machine simulator
  6. Download the part program(s) to the appropriate machine(s)
  7. Verify the program(s) on the actual machine(s) and edit if necessary
  8. Run the program(s) and produce the part
