Installation and commissioning phase Technical requirements Ambient temperature and humidity requirements. CNC lathes generally require the use of a constant temperature environment to ensure the accuracy of the machine tool, generally requiring a constant temperature of about 20 degrees Celsius. A lot of practice has proved that in the summer high temperature period, the failure rate of the numerical control system is greatly increased and it is easy to cause a collision accident. The wet environment will also reduce the reliability of the CNC lathe operation. Therefore, the dehumidification measures should be taken for the environment of the CNC lathe in order to avoid circuit short-circuits, resulting in misoperation of the CNC system and collision accidents. At the same time, CNC lathes are required to be far 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 machine tools and electric discharge machine tools.
The standardization debugging actions mainly include the following points:
1) When debugging the program, you must hit the G00 speed selector switch at F0 to allow the tool to approach the workpiece at a slow speed. Otherwise, once the tool offset is wrong, the tool moves from the tool change point to G00 in a very fast manner. At that point, there may be a strong collision with the workpiece, so that the operator is at a loss, and it is too late to rule out dangerous situations. On the contrary, when the tool is approached at a slower speed, even if the tool is misaligned, the operator has plenty of time to adjust.
2) When debugging the program, the CNC lathe must be single-stepped. After the operator executes the previous block on the CNC lathe, it must check the correctness and rationality of the next block again and make adjustment accordingly.
3) During the movement of the CNC lathe, the operator must always observe the change of the tool coordinates on the screen and whether the coordinate of the movement end point in the program is consistent with the coordinates of the actual movement of the tool.
4) During program debugging, the operator can place one finger on the cycle start button and the other finger on the cycle hold button so that the execution of the program can be stopped in an emergency. At the same time, always remember the location of the emergency button in order to meet the need.
When starting up the machine, the machine reference point setting is generally performed. The coordinate system of the machine tool workpiece should be consistent with the programmed coordinate system. If there is an error, the possibility of collision between the turning tool and the workpiece is very high. In addition, the tool length compensation must be set correctly; otherwise, it will either be empty or crashed.
5) The program's debug phase uses computer simulation capabilities. With the development of computer technology, the continuous expansion of CNC machining teaching, more and more numerical simulation simulation system, its function is increasingly perfect. It can therefore be used in preliminary inspection procedures to observe the movement of the tool to determine if a collision is possible.
The use of CNC lathes comes with a graphical simulation of processing functions. Generally more advanced CNC lathes all have graphic analog processing functions. Before the automatic machining, in order to avoid program errors, the tool may collide with the workpiece or the chuck, and the entire machining process may be graphically simulated to check whether the tool path is correct.
Strictly abide by the operating procedures to reduce the numerical control equipment operation accidents should not only from the management, process, training, supervision and inspection and other aspects of prevention, according to many years of experience in the numerical control and many cases of research, we summed up the following CNC machine tool to prevent operational accidents Procedures can play a positive role in the prevention of operational accidents:
1) The numerical control equipment shall be fixed and fixed, and shall not operate the equipment without qualification.
2) When two or more people operate the equipment, they must do a good job of negotiating and handing over the workpiece. It is forbidden to replace the equipment without the operator's consent.
3) Operators should continue to strengthen business learning and continuously improve their sense of responsibility.
4) Before the first piece of processing, the procedure must be carefully checked and automatic processing can be performed after the single-stage processing test.
5) After the program and data are modified, they must be strictly checked and executed according to the first processing step.
6) The choice of coordinate origin and tool change point in programming must be safety first and foolproof.
7) Reasonably select the cutting parameters, such as speed, cutting amount, feed rate, etc., to eliminate overloaded equipment.
8) Strictly inspect the workpiece blank. For the oversize (or too small) shape of the blank, it must be processed in advance.
9) Workpieces and props must be clamped in a necessary manner, in a reasonable position, and the clamping force must be properly adjusted.
10) Tool holder must be firm and reliable.
11) Care must be taken during operation to prevent collisions when manually moving the machine.
12) If there is any abnormality or a collision in the equipment, the maintenance personnel must be notified immediately to check the condition of the equipment and no delay shall be concealed.
13) It is forbidden to adjust and modify machine parameters without professional training and approval.
14) Conscientiously and in accordance with the operating instructions, maintain the equipment on time every day and fill out the equipment checklist.

Since the CNC lathe is automatically processed according to the programming instructions programmed by the programmer, although there are many simulation and simulation software programs that can detect the program, it still causes a collision accident for the machine tool due to various reasons. In this regard, the China Machine Tool Network specially stipulated the safety rules for the production of machine tools, and reminded the majority of machine tool workers to pay attention to safety.
