Top 4 CNC Machine Problems and How to Troubleshoot Them
25 July 2022Computer numerical control or CNC machining has been simplifying key manufacturing processes ever since it has been adopted by industries. One great thing about CNC machining is it automates the movement and operation of various industrial tools, which makes every process efficient and safe. CNC machining does not likewise generate waste and defects. It even minimises energy use.
The benefits associated with CNC machining increase as technological advancements continue. From the software that handles the behaviour of the tools down to the tools themselves, more valuable changes can surely be expected out of this type of machining, especially when cutting, shaping, and creating a wide array of parts and prototypes.
Problems, however, may still arise when using CNC machines. Here are some of the most common problems with CNC machines and some ways to troubleshoot them.
- Programming Errors
One CNC machine problem that may arise during its operation is the existence of programming errors. Compared to manual machining, the integration of software makes CNC machining more efficient and safer. Programming errors, however, may still occur due to improper setup and feeding of erroneous data variables into the CNC controller. The lack of knowledge of G and M codes used for the controller can also cause programming errors. One way to prevent these errors is to train new CNC operators, which can be done by handing out manuals and teaching them the technicalities of CNC machining.
- Poor Final Build Quality
Another CNC machine problem that industries may encounter is the generation of poor final build quality. CNC machines are intended to produce parts and prototypes without any issues with their dimensions, surfaces, and others. If these machines, however, produce products with rough edges, burn spots, or raised marks on their corners, it means they have utilised the wrong cutting tools. These things may also happen due to wrong cutting settings. Choosing the right machining tools can help resolve this issue. Applying the right setting for the build quality and material can also prevent this problem.
- Machine Inaccuracy
CNC machines and tools can work effectively if they are inspected and maintained regularly. The purpose of inspecting them is to ensure that their components are still intact. It can likewise assess if there is any build-up of dust, dirt, and other debris. Once they are spotted, they must be cleaned immediately. Failure to clean them, after all, may lead to inaccuracies in machining. The accumulation of these elements can also lead to the total breakdown of the machines. By cleaning and maintaining the machines and tools regularly, any costly delays in the project will be eliminated.
- Overheating Tools
One more problem with CNC machines that industries may run into is overheating tools. Tools can get hot when they repeatedly come into contact with metal workpieces. However, if they reach over 150 degrees, the tools may start to affect the results of the machining process. The quality of the products may deteriorate, forcing the manufacturers to restart the creation of the parts and prototypes. One thing that can be done to avoid overheating tools is to remove any dirt, debris, or soil on the tools and the machines. Proper lubrication and ventilation can also be done to prevent overheating tools.
