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
