Understanding CNC Machining Materials
Choisir le bon Matériaux CNC is key to a project’s success. Each material has its own strengths and weaknesses. These affect how well it works and how strong it is.
Metals like aluminum and acier inoxydable, and plastics are common Matériaux CNC. Knowing about these helps us make better choices. Here are important things to think about:
- La force : How well a material holds up under stress matters a lot.
- Usinabilité : Some materials are easier to work with, saving time and tools.
- Stabilité thermique : Materials that keep their shape in changing temperatures are very important.
By carefully looking at these factors, we can make sure every project goes well.
Key Properties of CNC Materials
It’s important to know the key properties of Matériaux CNC. This helps us make the right choice when picking materials. We’ll look at mechanical, thermal, and cost factors of different materials. This will help us find the best solution for any project.
Propriétés mécaniques
Mechanical properties are key. They include tensile strength, hardness, and resistance to wear and impact. These tell us how materials perform under stress.
Par exemple, acier inoxydable has a tensile strength of 500 to 750 MPa. Titanium alloys can go over 1,000 MPa. This makes them great for parts that need to hold a lot of weight.
Hardness is also important. It shows how well a material can resist being deformed. Brass is very ductile, making it easy to shape into detailed designs. Titanium also stands out for its durability, perfect for parts that need to last a long time.
Thermal Properties
Thermal properties are about how materials handle heat. Aluminum and copper are good at conducting heat, with values of 237 W/(m·K) and 401 W/(m·K), respectively. This helps keep the machine cool during cutting, preventing damage.
On the other hand, materials that don’t conduct heat well need special cooling. This ensures the machine works well and lasts longer.
Facteurs de coût
Cost is a big factor in choosing CNC materials. We need to look at the material cost and any extra steps needed after machining. Aluminum is cheap and easy to work with, saving money in the long run.
But, harder materials like titanium alloys cost more. They wear down tools faster and need special machines. Also, how easy it is to get the material and any extra steps like heat treatment can affect the total cost.
