In CNC machining, what is "synchronization" necessary for?

Synchronization in CNC machining is essential for coordinating multiple axes to ensure that complex geometries are accurately machined. This process allows the machine to operate in a manner where several axes move simultaneously and in harmony, which is critical for producing intricate shapes and contours. When performing tasks such as 3D milling or contouring, for example, synchronization ensures that the precise movement of each axis aligns with the intended design, leading to accurate and efficient machining.

The ability for multiple axes to work together seamlessly is crucial for handling complex operations that would be impossible or inaccurate if each axis worked independently. This is particularly significant in scenarios that require continuous path motion, where the movement between axes must be synchronized to maintain the tool's position in relation to the workpiece.

In contrast, limiting the number of axes, operating at lower speeds, or managing the power supply, while important considerations in their own right, do not address the primary purpose of synchronization in CNC machining.
