Question: 1 / 400

What is the primary disadvantage related to quality in an open loop CNC system?

Quality remains consistent

Stricter quality control is required

In an open loop CNC system, the main disadvantage related to quality is that stricter quality control is required. This is because an open loop system does not use feedback mechanisms to monitor and adjust the output based on the actual performance of the machine. Instead, it operates strictly on predetermined inputs without checking if the desired parameters are being met during the cutting process.

As a result, issues such as deviations in tool wear, material inconsistencies, or environmental changes can lead to variations in product quality that the system cannot automatically correct. To ensure high-quality outputs, operators need to implement more stringent quality control measures to detect and resolve any discrepancies manually. This means increased attention to detail and more frequent checks on the manufacturing process to maintain the required standards.
