CNC machining is highly efficient. However, it has several limitations that businesses should consider.

First, the initial investment is substantial. Purchasing CNC machines requires a large amount of capital, and the cost of installation, maintenance, and repair is high. Skilled operators are also needed, and they often command high salaries.

Secondly, setup times can be long. Programming and configuring machines for a new task demands significant time and expertise. This can be a major drawback when dealing with small - batch production, as the extended setup time may offset the advantages of precision and speed.

Finally, despite its high precision, CNC machining may struggle with complex, irregular shapes. Some unique designs are extremely challenging to program and execute, potentially leading to production delays or even requiring alternative manufacturing methods.

In conclusion, while CNC machining offers many benefits, it’s crucial to be aware of its limitations for better production planning.
