Learning these CNC machining programming tips will always be used!
Buying a CNC lathe,ranging from a few hundred thousand to more than one million,so CNC lathes are very expensive.In the process of machining with CNC lathe,it is necessary to let the CNC machining center avoid collisions,because the maintenance cost will be high,how can we avoid it?That is to pay attention to the reasonable programming and reasonable operation.Learning these CNC machining programming tips will always be used!
1.Using computer simulation system
With the development of computer technology,the teaching of CNC machining has been continuously expanded,and more and more CNC machining simulation systems have been developed,and its functions have become more and more perfect.Therefore,it can be used in a preliminary inspection procedure to observe the movement of the tool to determine if a collision is possible.
2,using the CNC display center's own analog display function
Generally,more advanced CNC machining centers have graphic display functions.After entering the program,you can call the graphic simulation display function to observe the movement path of the tool in detail to check whether the tool can collide with the workpiece or the fixture.
3.Using the dry running function of the CNC machining center
The correctness of the path of the tool can be checked by using the dry running function of the CNC machining center.After the program is input into the CNC machining center,the tool or workpiece can be loaded,and then the empty running 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 be in contact with the workpiece or fixture.bump.However,in this case,it must be ensured that the tool cannot be loaded when the workpiece is mounted;when the tool is loaded,the workpiece cannot be loaded,otherwise collision will occur.
4,using the CNC machining center lock function
General CNC machining centers have a locking function(full lock or single axis lock).When the program is input,the Z axis is locked,and the coordinate value of the Z axis 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 will not pass.
5,the coordinate system,knife compensation settings must be correct
When starting the CNC machining center,be sure to set the CNC machining center reference point.The working coordinate system of the CNC machining center should be consistent with the programming time,especially the Z-axis direction.If there is an error,the possibility of the milling cutter colliding with the workpiece is very large.In addition,the tool length compensation must be set correctly,otherwise it is either empty machining or collision.
6,improve programming skills
Programming is a critical part of CNC machining,and improving programming skills can largely avoid unnecessary collisions.
In short,mastering the programming skills of the machining center can better improve the processing efficiency and processing quality,and avoid unnecessary errors in the processing.This requires us to continuously sum up experience in practice and continuously improve,so that the programming and processing capabilities are further strengthened.Of course,this is also part of protecting CNC lathes and reducing costs.
