1. The use of computer simulation system
With the rapid spread of contemporary computer technology and the continuous expansion of CNC machining teaching, the axis CNC machining simulation system is becoming more and more functional. Therefore, the technology can be applied to check the program: observe the movement of the tool to determine whether there is a collision. Using the machine's built-in simulation indicates the function. Generally, the more advanced CNC lathe graphic display function can be used when entering a program to observe the tool's motion trajectory in detail in order to check whether the tool may collide with the workpiece or fixture.
2. Using professional CNC machining locking processing function
General CNC lathe has locking function (full lock or single axis lock). After inputting the program, locking the two axes can be used to determine whether a collision will occur based on the coordinate values of the two axes. The application of this function should bypass operations such as tool change, otherwise it cannot be carried out according to the program.
3, coordinate system, tool complement settings must be correct
When starting CNC machining, remember to set the machine positioning point. CNC CNC machining work coordinate system should be consistent with the programming when R hold, especially the seven-axis direction. The probability of collision between the milling tool and the workpiece is particularly high if there is an unexpected error. In addition J tool length compensation must be set correctly J. Otherwise, either empty processing, or collision occurs.
4, the use of CNC CNC machining custom air work function
The use of this function can check the accuracy of the tool feed track. When the program into the machine tool, you can install the tool or workpiece, and then press and hold the empty run button. At this point, the spindle does not rotate and the console runs automatically according to the program trajectory. At this point, you can find out if the tool may collide with the workpiece or fixture. However, in this case, you must make sure that no tool can be installed when the workpiece is equipped; no workpiece can be installed when the tool is installed, otherwise a collision will occur.
