Jiexiang CNC machining center tells you the safety of CNC machining
CNC machining is the product of technology. It can process some precision parts and can also process some precision instruments. Now many aluminum shells are made by CNC machining technology. CNC machining brings a lot of convenience. Jiexiang CNC machining center Let me talk about the safety of CNC machining:
1. The coordinate system and tool compensation must be set correctly.
When starting CNC cnc machining, be sure to set the machine reference point. The CNC cnc machining work coordinate system should be consistent with the R when programming, especially the 7-axis direction. If there is an error, the possibility of the milling cutter colliding with the workpiece is very large. In addition, the setting of the J tool length compensation must be correct. Otherwise, it is either empty machining or collision.
2, using the computer simulation system
Nowadays, 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 for a preliminary inspection procedure: observe the movement of the tool to determine if it is possible to collide. Take advantage of the analog display function that comes with the machine. Generally, the graphic display function of the more advanced CNC machine tool can call the graphic simulation display function after inputting the program, and observe the movement track of the tool in detail to check whether the tool and the workpiece or the fixture are likely to collide.
3, using the locking function of CNC cnc processing
General CNC machines have a locking function (full lock or single axis lock). When the program is input, the 2 axes are locked, and the coordinate values of the 2 axes can be used to determine whether a collision will occur. The application of this function should avoid the operation of tool change, otherwise the program cannot pass.
4, the use of CNC cnc processing of the dry run function
The correct operation of the path of the tool can be checked by the dry running function of the CNC cnc machining. After the program is input into the machine, the tool or workpiece can be loaded, and then the empty run button is pressed. At this time, the spindle does not rotate, and the table automatically runs according to the program path. At this point, it can be found whether the tool is likely to collide with the workpiece or the fixture. However, in this case, it must be ensured that the tool cannot be loaded when the workpiece is mounted; the workpiece cannot be loaded when the tool is loaded, otherwise collision will occur.
The above is about the safety of the CNC machining center. CNC machining must learn to operate, otherwise it may damage the CNC machining lathe or cause waste of parts.
