The machining characteristics of new materials on CNC precision machining technology is mainly reflected in the following aspects:


1. Machinability of materials

The machinability of different materials directly affects the efficiency and quality of CNC machining. For example, aluminum and plastics are usually well machinable and can be cut quickly and accurately, while materials such as carbide and titanium may require more complex cutting tools and parameter settings to cope with their higher hardness and strength. Choosing the right material is therefore critical to ensure a smooth machining process.


2. Thermal management

During CNC machining, the heat generated by cutting affects the temperature of the workpiece and tool, which in turn affects machining accuracy. Newer materials such as titanium alloys generate higher heat during machining and therefore require effective cooling systems and optimized cutting parameters to reduce the impact of thermal deformation on accuracy. This requires consideration of the thermal properties of the material while selecting it so that machining strategies can be developed accordingly.


3.The hardness of the material affects the tool selection and wear rate. Harder materials, such as certain stainless steels and titanium, can cause rapid tool wear, so more wear-resistant tool materials (such as diamond-coated tools) are required to extend tool life and maintain machining accuracy.26 Also, hardness affects cutting speeds and feed rates, and manufacturers need to tailor these parameters to the specific material.

Harder materials, such as certain stainless steels and titanium, can cause rapid tool wear, so more wear-resistant tool materials (e.g., diamond-coated tools) are required to extend tool life and maintain machining accuracy. Also, hardness affects cutting speeds and feed rates, and manufacturers need to adjust these parameters for specific materials.


4. Manufacturing complex geometries

New materials are often used to manufacture parts with complex geometries, such as critical components in aerospace and medical devices. cnc technology enables precision machining of highly complex parts with multi-axis capabilities, but it also requires operators to have the experience to flexibly adjust the process parameters between different materials.


5. Cost-effectiveness

New materials tend to be more expensive, making it necessary to balance performance needs with cost-effectiveness when selecting materials. For example, while titanium alloys offer superior performance, their high cost may not be suitable for all applications. Therefore, when performing CNC precision machining, manufacturers need to consider the cost of the material, the difficulty of machining, and the performance of the final product in order to optimize productivity and economy.


To summarize

The properties of new materials place greater demands on CNC precision machining technology in terms of machinability, thermal management, tool selection, ability to produce complex shapes, and cost-effectiveness. Manufacturers need to develop machining strategies based on these characteristics to ensure that all types of parts are produced efficiently and accurately.
