In addition to metals, CNC machining can also work with a variety of plastics and composites. These materials are often chosen for their lightweight, chemical resistance, and ease of machining. Common plastics used in CNC machining include ABS, polycarbonate, and Delrin, while composites like carbon fiber are favored for their strength-to-weight ratio and rigidity.

Advancements in CNC Machining Technology

The field of CNC machining is continuously evolving, driven by technological advancements that push the boundaries of what is possible. One of the most significant developments in recent years is the advent of multi-axis machining. Traditional CNC machines typically operate on three axes (X, Y, and Z), but multi-axis machines can operate on four, five, or even more axes. This added flexibility allows for the creation of more complex geometries and reduces the need for multiple setups, thereby improving efficiency and accuracy.

Another notable advancement is the integration of automation and artificial intelligence (AI) into CNC machining processes. Automation has been a game-changer in terms of productivity, allowing machines to operate continuously with minimal human intervention.
