What should we pay attention to in machining center processing technology and programming

In our CNC machining center, it is a delicate job. It requires careful coordination in drawing, programming, and machine adjustment to make the most accurate and beautiful workpieces.

Generally speaking, in terms of programming, I think there are several main aspects: the processing time should be as short as possible, but it should be within the tolerance range of the tool. It is necessary to avoid stepping on the tool and sudden feeding (feed and retract), consider how to sort the subsequent processes (for example, the surface is processed first, and it is difficult to do it later), consider how to do it to achieve the best processing effect and size, etc. Basics, if there are experts, add the process, first know how to make this part, what to do first, what to do later, how to install the card, the installation does not affect the tool processing, there should be no interference, you need to know the material and the tool material, what kind of workpiece material corresponds to what kind of tool material, so that the processing is stable, and there is also the problem of machine tool travel, the workpiece is too large and cannot be overtraveled. Under the premise of ensuring that the workpiece is stable, easy to install, and easy to process, consider the processing time and optimize it.

When processing, first do the parts with low precision, which will not affect the precision and appearance of the later parts, and then do the parts with higher precision and appearance. When programming, pay attention to interference, tool length, workpiece height, determine the workpiece coordinate system, and give reasonable tool parameters. The most important thing to pay attention to is whether there will be a collision with the tool.
