What Is The Sequence of CNC Router Operations?

General Procedure for CNC Operation:

1. Preparation

• Check the machine's condition: power supply, air supply, lubrication system, etc.

• Clean the worktable and check safety protection devices

• Wear proper personal protective equipment (PPE), such as safety glasses and steel-toe shoes

2. Workpiece and Tool Setup

• Clamp the workpiece securely using fixtures or a chuck, ensuring correct positioning

• Install and calibrate tools (using a tool presetter or manual tool setting)

• Set the workpiece zero point (work coordinate system), such as G54

3. Program Preparation

• Load or input the machining program (G-code) via USB, network, or manual input

• Check the program for correctness (coordinates, paths, tool numbers, etc.)

• Perform a dry run (simulation) to ensure there is no risk of collision

4. Parameter Setup

• Set spindle speed, feed rate, coolant switch, and other relevant parameters

• Verify tool compensation (offsets), length offsets, etc.

• Set up the machining coordinate system (e.g., G54 to G59)

5. Program Execution

• Start the spindle and coolant, then begin automatic machining

• Monitor the machining process closely for any abnormalities

• Pause or manually intervene if necessary to make adjustments

6. Post-Machining Handling

• After completion, turn off the spindle and coolant system

• Remove the workpiece and inspect for quality (dimensions, tolerance, surface finish, etc.)

• For batch production, replace the workpiece and repeat the program

7. Cleaning and Maintenance

• Clean out chips and coolant from the machine

• Inspect tools and fixtures for wear

• urn off the power and complete the daily maintenance checklist

✅ Tips:

• Beginner operators must be properly trained and familiar with emergency stop procedures

• Always simulate and check the program before actual cutting

• Keep the workspace clean and organized to avoid accidents or mistakes
