1. The coordinate system and tool compensation settings must be correct

When starting CNC Machining, it is important to set the reference point of the machine tool. The CNCCNC machining operation coordinate system should be consistent with the programming R, especially in the 7-axis direction. If there is an error, the milling cutter may collide greatly with the workpiece. In addition, J tool length compensation is necessary for setting the correct J, otherwise it will either result in empty machining or collision.

2. Adopting a computer simulation system

Nowadays, with the development of computer technology and the continuous expansion of CNC machining education, there are more and more CNC machining simulation systems, and their functions are becoming more and more perfect. Therefore, it can be used to start viewing programs: investigating the movement of things to acknowledge whether there may be any bumps. Utilize the built-in simulation display function of the machine tool. The graphic display function of CNC machine tools can be called upon to simulate and display graphics when inputting programs, specifically investigating the motion trajectory of the tool to see if there is any collision between the tool and the workpiece or fixture.

3. Using CNC machining to confirm functionality

Generally, CNC machine tools have a confirmation function (full lock or single axis lock). When the input program confirms two axes, the coordinate values of the two axes are used to determine whether collision will occur. The use of this function should prevent operations such as tool changing, otherwise the program cannot pass through.

4. Using CNC machining for air transportation function

The use of CNCCNC machining lift function can check the correctness of the tool path. When the program enters the machine tool, it can install the tool or workpiece, and then press the air transport button. At this moment, the spindle does not roll, and the worktable automatically runs according to the program track. At this moment, it can check whether something may come into contact with the workpiece or fixture. However, in this situation, it is necessary to ensure that no cutting tools are installed when installing the workpiece; When installing cutting tools, do not install the workpiece, otherwise it may collide.

CNC machining must be learned to operate, otherwise it may damage the CNC machining lathe or result in the scrapping of parts.
