Advanced CNC Machine VS Standard CNC
Standard CNC milling vs advanced CNC milling
Advanced CNC machining uses specialized equipment and automation procedures that improve the machining capabilities compared to standard CNC machining.
Advanced CNC machining uses the modern 5-axis machining technology that increases versatility by enabling multi-angle manipulation. This improves the production time by removing the old multi-setup process.
Standard CNC machines are based on 2D and 3D axes, limiting versatility and generally suitable for high-volume parts production with simple geometries.
Advanced CNC machining has higher precision and is better at achieving tight tolerances. It can easily machine up to 0.001 inches. This helps in manufacturing complex geometries with crevices and tight corners.
Standard CNC machines are only capable of 0.001 inches in precision and are limited to simple geometry.
The Advanced CNC machines have real-time monitoring capabilities and automatic tool changers, which adjust and streamline the machining process to reduce lead time. This means that there are minimal flaws and human intervention during production.
The Makino 5-axis machine is an example of an advanced CNC machine that can perform multiple operations in a single cycle. Standard CNC machines require multiple setups for such jobs.
Standard CNC machines are better suited for simple, high-volume part production. In contrast, advanced CNC systems are for parts with complex designs with strict industry requirements, such as the aerospace and automotive industries.

Key Processes in Advanced Machining
Advanced CNC machining uses cutting-edge technology to achieve high precision and tight tolerances. These efficient methods and techniques maintain consistent quality and timely production. Some advanced techniques used in modern CNC machining are mentioned below:
High-Speed Machining (HSM)
High speed milling
High-speed machining is highly precise. It uses a high-speed rotating spindle that removes excess material to form a component.
It has generated less heat than other techniques and is used for aluminum machining since it can bypass the problem of aluminum’s high conductivity.
For optimal performance, HSM requires careful attention to feed rates and tool wear during machining.
The Makino MAG series machine is an excellent one with a spindle speed up to 33000 RPM for enhanced precision and efficiency.
Additionally, high-speed machining produces high-quality surface finishes. This removes the need for post-processing.
Cryogenic Machining
Cryogenic machining is an advanced CNC machining technique that uses liquid nitrogen or carbon dioxide to cool the material and cutting tools during machining.
Cutting tools and drills can reach extremely high temperatures when machining materials such as titanium and Inconel. The high temperature reduces tool life.
A cooling system delivers coolant to the cutting tool to prevent wear and regulate temperature.
The process is used in the aerospace and energy industries to improve cutting speed and reduce component processing time.
Laser-Assisted Machining (LAM)
Laser assisted machining
Laser Assist Machining uses a laser to heat the material in the cutting zone. The laser can improve cutting by reducing friction and providing localized heating. It is widely used in processing hard materials such as ceramics and super alloys.
Most advanced systems use LAM to manufacture superalloy components such as turbine blades with precision and efficiency.
Ultrasonic Assisted machining (UAM)
Ultrasonic-assisted machining uses ultrasonic waves to reduce the friction between the tool and the material. The reduced friction means less heat buildup, which leads to a more efficient machining process.
The aerospace industry uses 5-axis CNC machines with UAM to reduce the risk of microfractures and delamination when machining brittle ceramics or composites such as CFRP.
Adaptive Machining
