What is a disadvantage of using CAM?

Using Computer-Aided Manufacturing (CAM) can indeed present particular challenges, especially with one-off production runs. The primary disadvantage here is related to the efficiency and time taken for setups. For one-off or bespoke items, CAM systems might require significant time for programming and setup to produce a single unique item. This setup time can often exceed the time needed for simpler traditional manufacturing methods, where tools and processes are more straightforward and can be adjusted quickly by a skilled operator.

In contrast, CAM systems thrive in high-volume production scenarios where the benefits of automation and precision are maximized. For low-volume production, the time and cost associated with programming CAM machines can make it less viable compared to traditional methods that may adapt more swiftly to changes in production requirements without extensive preparation.
