SETTING UP A CNC MACHINE FOR MACHINING

CNC machine setup and operation follows the process below:

1. Pre-Start

2. Start/Home

3. Load Tools

4. Mount Remove Part into the vise

5. Set Tool Length Offsets Z

6. Set Part Offset XY

7. Load CNC Program

8. Dry Run

9. Run Program

10. Adjust Offsets as Needed

11. Shut Down.

1. Pre-Start:

Before starting the machine, it should be checked to ensure oil and coolant levels are full. The machine maintenance manual should be checked to ensure how to service it. Clear of any loose tools or equipment should be ensured in the work area. If the machine requires air supply, the compressor should be ensured in ON condition and the pressure meeting the machine requirements.

2. Start/Home:

Power should be turned ON to the machine and control. The main breaker is located at the back of the machine. The machine power button is located in the upper-left corner on the control face.

3. Load tools:

All tools should be loaded into the tool carousel in the order listed in the CNC program tool list.

4. Mount the part in the vise:

The part to be machined should be placed in the vise and tightened.

5. Set tool length offsets:

Tool length offsets should be set for each tool used in the order listed in the CNC program, jog the Tools to the top of the part and then set the TLO.

6. Set part offset XY:

Once the vise or other Part is properly installed and aligned on the machine, the fixture offset should be set to locate the part XY datum.

7. Load CNC program:

CNC program should be loaded into CNC machine control using USB flash memory, or floppy disk.

8. Dry run:

Next, the program should be run in the air about 2.00 in. above the part.

9. Run program:

The program should be run using extra caution until the program is proven to be error free.

10. Adjust offsets as required:

The part features should be checked and adjusted the CDC or TLO registers as needed to ensure the part is within design specifications.

11. Shut down:

The part should be removed from the vise and tools from the spindle, the work area should be cleaned, and properly the machine should be shut down. the work area should be cleaned and the machine and tools should be left in the location as per the condition you found them.
