In this contemporary technological era, CNC machining has bought a revolution in the industrial manufacturing area. It simply implies the computerized management of manufacturing machining tools such as lathes, drills, boring tools, etc. All equipment is handled and controlled by the software present in CNC machining. It ameliorates industrial production’s capacity, efficiency, and accuracy to extensively manufacture goods or other components. In this article, you’ll get a complete guide on prototype CNC machining materials.
Explanation of the CNC In The Manufacturing Industry
CNC is the short form and it stands for Computer Numerical Control. It refers to any computer-controlled machining process. If we compare it with manual machining, computerized automation allows the production of the parts with fantastic accuracy, complexity, speed, and precision. Moreover, CNC eradicates the work of human beings. Despite the fact that they are not doing every work, individuals are mandatory for programming as well as running the machinery to make sure that everything runs well.
The Most Commonly Used Materials For CNC Machining
Below are some commonly used materials for this process:
Aluminum: It is the most typically used material due to its features such as lightweight, excellent strength-to-weight ratio, and high machinability.
Brass: It is a copper-zinc alloy often used in CNC machining because of its high strength, incredible machinability, and corrosion resistance. It is repeatedly used in building electrical components, plumbing fixtures, appliances, and musical instruments.
Copper: It is a good conductive metal and this is why it is used in electrical components. It is also used in making cooking appliances, plumbing fixtures, and electronic elements.
Steel: Steel is a versatile and durable material that is used in a wide range of CNC machining applications. It is oftentimes used in making automotive parts, machine components, and industry tools.
Titanium: This is a lightweight and corrosion-resistant metal and has an excellent strength-to-weight ratio and high-temperature resistance.
Importance Of Selecting The Right Material For CNC Prototype Machining
Selecting the right material is necessary for the success of any project. The choice of material affects the cost, durability, and functionality of the final product.
One primary consideration is the strength and durability required for the application. Another thing to consider is the cost of the process. Some materials, such as titanium, are more expensive than others, such as aluminum. The cost of the material must be balanced with the performance requirements and the budget of the project.
Paying attention to the machining properties of the material is also important. Some materials, such as aluminum and brass, have excellent machinability, which allows for faster production and lower costs. Other materials, such as titanium and hardened steel, are more difficult to machine and require specialized tooling and techniques.
What Is The Maximum Thickness Of Metal That Can Be Cut Using A CNC Machine?
CNC cutting machine can cut carbon steel of up to 9 mm in a minute and the max limit is 19 mm and can cut stainless steel for 15mm. They use high-temperature plasma arc quantity of heat to make up the metal parts of the workpiece partial or slit and borrow the plasma momentum to eliminate a molten metal to make up an incision.
How To Pick The Right Prototype CNC Machining Materials?
Choosing the accurate material relies on numerous aspects such as the needed durability, strength, cost-effectiveness, and surface finish.
Machining Environment
It is crucial to consider the environment of machining when selecting CNC materials because distinctive materials react distinctly to various machining conditions like tool material, cutting speed, and coolant. The machine environment includes many factors like humidity, the presence of contaminants, and temperature.
Part Weight
It is crucial to consider the weight of the parts to make sure manufacturability, performance, and cost-effectiveness. Heavier parts need more material, which can escalate the production cost. Moreover, heavier parts need more sturdy and significant machines to manufacture, which inclines the production time and cost. Thus, selecting the accurate material with lower density, like magnesium, or aluminum can help in reducing the weight of the part and lesser production costs.
Heat Resistance
Selecting CNC materials that are heat resistant can help to improve the machining procedure and mitigate the cost of production. When a material is heating resistant, it enables deeper cuts and swift cutting speeds.
Hardness
It is pivotal to check the hardness of the material while choosing CNC materials. If a CNC material is too hard, it can be arduous to shape or cut it which results in tool breakage, tool ears, and a poor finish.
The hardness of the material is important as it can also put a great impact on the efficiency and speed of the machining procedure. Because harder materials may need slower cutting speeds or more sturdy cutting tools.
Electrical Conductivity
Electrical conductivity is a like a measure to check the ability of the material to conduct electricity. In CNC machining, high electrical materials are preferred because they can dissipate heat easily.
Magnetic Requirements
Materials that are non-magnetic, like stainless steel and titanium are preferred for CNC machining because they are not affected by the magnetic field and therefore produce a sharp cut.
Budget
Budget is an indispensable factor to consider as the cost of the material depends on the quantity and type required. Setting up a budget will aid you in narrowing down your options and you can focus on the materials within your budget.
Steps To Select The Right Kind Of Material
Step 1: Define the application requirements
The first step in determining the right material is to define the requirements. Consider factors such as the environment in which the end product will operate, the stress and load it will be subjected to, and any functional requirements.
Step 2: Determine the material properties required
Based on the application requirements, determine the material properties required, such as strength, durability, corrosion resistance, and machinability.
Step 3: Evaluate the material options
Evaluate the material options based on the required properties, cost, and availability. Consider multiple materials and compare their properties, costs, and availability to determine the best option for the project.
Step 4: Consider the machining properties
Evaluate the machining properties of the chosen materials, such as their machinability and the availability of tools and techniques for machining. Choose a material that can be machined efficiently and effectively.
Step 5: Consider the finishing requirements
Consider any finishing requirements, such as surface finish or coating, and choose a material that can meet these requirements. Some materials may require additional steps or processes to achieve the desired finish or coating.
Step 6: Prototype and test
Once a material has been selected, prototype and test the component to ensure it meets the required performance and functional requirements. Make any necessary adjustments to the material or design to optimize the performance and functionality of the component.
