How to decide whether to use four-axis or five-axis machine tools for NC machining?

This should be considered from two aspects.

1. If the processing batch of simple polyhedral parts is large, considering the processing efficiency and reducing the number of clamping, four-axis and five-axis machine tools can be considered.

2. If it is a complex and high-precision part, it is necessary to avoid the error of repeated clamping and use a four-axis or five-axis machine tool.
