What Should Be Considered When Selecting A Material For CNC Machining?
- Part application. The general application scenario will determine the physical properties of the part material, such as tensile strength, strength-to-weight ratio, crack resistance, rigidity or flexibility, etc.
- Appearance and the cost of the material. For example, the appearance of consumer products generally require aesthetic and low cost parts.
- Operating environment. Operating conditions include temperature, harsh chemicals, exposure to ultraviolet radiation, constant contact with water, and even exposure to flame.
