Computer numerical control (CNC) equipment has become popular because it is capable of working accurately and consistently in a wide range of industries. This makes it an invaluable tool for a variety of operations, from drilling and milling to complex manufacturing procedures. However, when the CNC equipment malfunctions or requires maintenance, it can cause a massive disruption in any process.
In this case study we discuss an example of CNC maintenance. The equipment in question is a CNC machine used for manufacturing medical implants. The reality of medical equipment maintenance is that it is typically very expensive and requires highly-specialized technicians. This case highlights the importance of proper and timely maintenance to maximize the productivity of CNC machines.
The problem began when the CNC machine encountered an error. Initially, the technicians removed the error code and the machine resumed normal operation. However, several days later, the same error occurred. After the technicians removed the error code again, the machine resumed normal operation again, but after a few hours the same error code re-appeared.
At this point, it was determined that the cause of the error codes was a defective hard drive. The hard drive needed to be replaced but the new drive was unavailable. The technicians considered using a used hard drive to replace the defective one but the patient safety regulations of the company did not allow for it. Furthermore, the company policy was such that they only purchase new hard drives in order to guarantee their quality.
After a lengthy consultation, the technicians decided to use a combination of software and hardware alterations to repair the CNC machine. First, the processor was changed in order to ensure that the new hard drive would be compatible. Then, the technicians used a diagnostic software to pinpoint and repair any corruptions in the software that were causing the error codes. Finally, the software was updated and the hard drive was installed. After the update and installation, the CNC machine was back up and running correctly.
The case highlights the importance of proper or timely maintenance for CNC machines. Many companies do not have a policy of servicing these machines on a regular basis, which can lead to unexpected and costly repairs. Furthermore, it demonstrates how trained technicians can often use creative solutions to solve complex problems. In this case, the technicians were able to bypass the need for a new hard drive by using software and hardware alterations.
Overall, this case highlights the importance of understanding the need for maintenance of CNC machines in order to maximize their productivity. Companies should carefully consider their policies as to how and when machines should be serviced and repair, especially for those machines which are responsible for high-precision manufacturing. CNC machines are valuable tools and an understanding of their servicing and repair needs is essential.
