Modern CNC machine is considered a complex electromechanical device. For proper operation, it requires the service of qualified specialists. As a rule, the work of such machines is supervised by an adjuster and a CNC machine operator.

The work of an adjuster is more complex and responsible. He must perform the adjustment and readjustment of the machine. The CNC machine operator controls the process and can only make light adjustments.

Actions of the installer

1. According to the map, a cutting tool is selected. Then its integrity and correctness of sharpening are checked.
2. The specified coordinate dimensions are selected according to the setup map.
3. Install the cutting tool into the revolver.
4. Install the chuck specified in the setup sheet and check the workpiece for secure fastening.
5. The switch is set to the "From the machine" position.
6. Next, the test of the working system at idle begins.

7. After checking the tape drive, enterperforated tape. Thus, the adjuster is convinced of the correctness of the programmed program for the console and the machine, as well as the working light signaling system.

8. Next, you need to move the caliper to the zero position using the Zero Shift switches.
9. Specialist secures the workpiece in the chuck.
10. He also sets the switch to "According to the program".
11. Begins processing the first piece.
12. The manufactured part is measured, corrections are made for correctors-switches.
13. The workpiece is processed in the "According to the program" mode again.
14. Measuring the finished part.

And before the CNC machine operator starts work, the mode switch on the device’s remote control is set to the “Automatic” position. This completes the machine setup process.

CNC machine operator

The routine maintenance of this specialist includes changing oils, cleaning the working area, lubricating the chuck, checking the hydraulics and pneumatics of the machine, as well as the accuracy parameters of the equipment.

Before starting work, the CNC operator must:

1. Check the performance of the machine using a special test program embedded in the equipment. Check for lubrication, hydraulic oil and limit stops.

2. The CNC machine operator checks the fastening of fixtures and tools,whether the workpiece corresponds to this technological process. It measures deviations from the accuracy of zero adjustment on the machine, the difference in deviations for each given coordinate and the runout of the tool in the machine spindle itself.

   

3. Then the machine is turned on. It is necessary to install and fix the workpiece, enter the program, fill the magnetic tape and punched tape into the reader, press the "Start" button.
4. After processing the first part, measure for compliance with the drawing.

CNC machines are reliable enough equipment to work without failure for many years. However, one should not lose sight of the human factor leading to accidents. An insufficiently qualified CNC machine tool setter and operator can cause the failure of such machines.
