What Are The Technical Requirements For CNC Machine Tools During The Installation And Commissioning Phases?

Ambient temperature and humidity requirements. CNC lathes generally require the use of ambient temperature to ensure the working accuracy of the machine, generally requires a constant temperature of about 20 degrees Celsius. A large number of practices have proved that the failure rate of the numerical control system is greatly increased during the high temperature period in summer, which is easy to cause collision accidents. The damp environment will also reduce the reliability of the operation of the CNC lathe. Therefore, the dehumidification measures should be taken in the environment of the CNC lathe to avoid short circuit of the circuit, causing misoperation of the CNC system and collision. At the same time, CNC lathes are required to be away from vibration sources such as forging equipment, away from electromagnetic field interference, away from electric welding machines, and away from electric cutting machines such as wire cutting machines and EDM machines.

 

Develop the standard debugging actions, including the following:

 

1) When debugging the program, the G00 speed selection switch must be placed on the F0 gear to allow the tool to approach the workpiece at a slower speed. Otherwise, once the tool offset is wrong, the tool moves from the tool change point to the feed in G00 mode. When the point is reached, there may be a strong collision with the workpiece, so that the operator is at a loss, and it is too late to eliminate the danger; on the contrary, when the tool is approached at a slower speed, even if the tool is wrong, the operator has sufficient time to adjust.

 

2) When debugging the program, the CNC lathe must be in a single-step state. After the operator executes the previous block on the CNC lathe, the correctness and rationality of the next block must be checked again and adjusted accordingly.

 

3) During the movement of the CNC lathe, the operator must constantly observe the change of the tool coordinates on the screen and whether the coordinates of the motion end point in the program are consistent with the coordinates of the actual movement of the tool.

 

4) During the debugging process, the operator can place one finger on the loop start button and the other finger on the loop hold button to stop the execution of the program in an emergency. At the same time, always remember the location of the emergency button so that it can be used from time to time.

 

When starting the machine, it is usually necessary to set the machine reference point. The machine tool coordinate system should be consistent with the programmed coordinate system. If there is an error, the possibility of the tool colliding with the workpiece is very high. In addition, the tool length compensation must be set correctly, otherwise it is either empty machining or collision.

 

5) The debugging phase of the program

 

Use computer simulation to simulate functions. With the development of computer technology, the teaching of CNC machining is constantly expanding, and more and more CNC machining simulation systems are being developed, and its functions are becoming more and more perfect. It can therefore be used in a preliminary inspection procedure to observe the movement of the tool to determine if a collision is possible. Use the graphic simulation processing function of the CNC lathe. Generally, the more advanced CNC lathes have the function of graphic simulation processing. Before the automatic machining, in order to avoid the program error, the tool collides with the workpiece or the chuck, and the whole machining process can be graphically simulated to check whether the tool path is correct.
