Many manufacturers know that in the process of CNC machining center, it is crucial to avoid collisions when programming and operating the machine tool. After all, CNC machining centers are not cheap, so it's important to save money and avoid expensive repairs. However, collisions during machining follow certain patterns. In order to minimize losses, Richconn-CNC has summarized the following points:
With the development of computer technology and the expansion of CNC machining teaching, there are more and more CNC machining simulation systems, which are becoming increasingly sophisticated. They can be used to check programs and observe tool movements to determine whether collisions are possible.
Most advanced CNC machining centers have graphic display functions. When the program is input, the simulation display function can be called to observe the movement of tools in detail to check whether collisions between tools and workpieces or fixtures are possible.
The air run function of the CNC machining center can be used to check the correctness of tool paths. After the program is input to the CNC machining center, the tool or workpiece can be installed, and then the air run button can be pressed. At this time, the main spindle does not rotate, and the worktable runs automatically along the programmed path. This can help to detect whether collisions between the tool and workpiece or fixture are possible. However, it is important to ensure that the workpiece is not installed when the tool is installed, and vice versa, as collisions can occur.
Most CNC machining centers have a lock function (full lock or single axis lock). After inputting the program, the Z-axis can be locked, and potential collisions can be detected through the coordinate value of the Z-axis. This function should be avoided during operations such as tool changes, as it may prevent the program from running.
When starting a CNC machining center, the reference point of the center must be set. The working coordinate system of the center must match the one used during programming, especially in the Z-axis direction. If an error occurs, the possibility of the milling cutter colliding with the workpiece is very high. Additionally, the tool length compensation must be set correctly; otherwise, it may result in either empty machining or collisions.
Programming is a crucial part of OEM CNC machining, and enhancing programming skills can largely avoid unnecessary collisions.
