1 Using The Wrong Cutting Tools / Settings
Choosing the wrong cutting tool for the job may often result in poor quality material finishes. This could be seen as rough edges, cutter marks on the surface, raised marks, or burn marks on the material’s edges or corners. Extensive tool wear may result from this error.
2 Errors In Programming
As highly sophisticated equipment controlled by CNC computers, much of the issues which arise in CNC machining often comes from programming. These may come from a lack of understanding of the different G and M codes used for the controller, wrong set-up, or inputting the wrong data variables into the CNC controller.
3 Poor Maintenance Of CNC Machine Tool
Modern machines with multiple constantly moving mechanical parts, CNC Machine Tools need to be regularly cleaned and maintained to keep them running optimally. Failure to clear away dirt, material and other debris could result in a build-up which over time can result in inaccuracies in machining or even machine failures.
4 Inadequate Worker Skill And Training
With increasing use of computing and programming, CNC machine tool operators these days need a different set of knowledge and skills. Without the right organisational, planning and programming skills, workers are unable to optimize the yield of these machines even if they have machining skill and experience using previous models of machines in the past.
5 Automatic Tool Changer Problems
Occasionally, you may face challenges with the automatic tool changer in your CNC Machine Tool. This could be resolved by learning every step of the tool changing process, and troubleshooting it by diagnosing what went wrong.
