In the CNC machining process, which improper operations will cause CNC lathe machining failure?
No matter how fast and efficient CNC lathes are, they can't go wrong. Like any other type of machine or tool, they create problems and require maintenance. The CNC machining process is like any other tool, and there are certain things you can do that could inadvertently damage these machines. There are also clear steps you can take to keep them in good working order.
While there are certainly many issues that can cause problems and errors in CNC machining, some are more common than others. These problems are also easily overlooked and easily misdiagnosed.
Let's take a look at some of the most common problems in CNC lathe machining.
1. Poor or improper maintenance
CNC machining equipment needs to be carefully cleaned and lubricated on a regular basis - otherwise problems can arise. Lack of cleaning can cause dust and debris to build up. This seems to be purely a hygiene issue, but could have real effects on the output of the machine.
For example, if you start to notice material slipping during the cutting process, the buildup of dust may prevent the machine from working properly and providing the most accurate instructions. If this problem continues to be solved, it will create challenges as machines struggle to position and keep material stationary. This leads to higher accuracy and precision issues, and ultimately more errors.
Improper lubrication can cause machine parts to stick or move incorrectly. This can lead to errors, as well as overheating and air blockage. Overheating and insufficient air can also cause problems, such as material movement during CNC lathe machining.
2. Incorrect settings or tools
Maybe one of your tools is dull, the cutting fluid or lubricant isn't working properly, or the tool is moving at the wrong speed. All of these problems cause similar problems. The most likely result of one or more of these problems is small burn marks on the edges and corners of the material.
The reason for this is simple. If the CNC machining tool moves too slowly, the material will be under the cutting edge for longer than it should. This can cause burns and scars. Likewise, if the coolant isn't working properly, it can get too hot, causing burns to the edges of the material.
If one of your tools has itself been burnt, you'll need to adjust the settings to suit your specific tool's needs to avoid scarring. Or, if the tool is too dull and won't cut properly, it may be time to replace it entirely.
In addition to burnt edges, some other visual signs of these types of problems should be noticed, such as rough edges, visible cut marks, and raised edges. All of these indicate that some devices are not functioning properly.
3. Improper or incorrect programming
Another problem that can cause serious problems with CNC machining is programming errors. This is a simple cause-and-effect question, as programming directly controls the creation of the product. Therefore, if the programming is not correct, the product will have problems.
These problems can be difficult to spot, especially when new or less experienced employees are involved. These employees may not have a completely accurate understanding of the machine's processes and may enter codes incorrectly. Although they recognize certain mistakes, they may not realize their own mistakes.
To fix this problem, an inexperienced employee might try to power the machine off and on again. This may start the machine and cause it to correct the problem. Meanwhile, the original problem - wrong encoding - remains undiscovered.
To avoid this, make sure every employee receives comprehensive and proper training on how to properly code CNC machines. This way, these types of easy-to-avoid errors are less likely to happen, and you'll be more likely to have a smooth and problem-free CNC machining process.
