CNC machining, which stands for Computer Numerical Control machining, involves the
automated removal of material from raw stock based on computer-generated instructions.
This versatile process can be applied to nearly any material, ranging from expanded polyurethane
foam to nickel superalloys. Common applications of CNC machining include the fabrication of parts
for various industries, ornamental furniture, and the production of turbine blades.
The cost associated with CNC machining is heavily influenced by factors such as required precision,
surface quality, quantity, material composition, and the overall complexity of the part.

| Common Stainless Steel Materials | |
| No. | Properties |
| Stainless steel 304/304L | Stainless steel 304L (CNC) has excellent mechanical properties and good machinability. Resistant to most environments and corrosive media. |
| Stainless steel 316/316L | Stainless steel 316L (CNC) has similar mechanical properties to 304, with higher corrosion and chemical resistance. Ideal for marine applications. |
| Stainless steel 303 | Stainless steel 303 (CNC) has excellent toughness, but lower corrosion resistance than 304. Ideal for high volumes, due to its excellent machinability. |
| Stainless Steel 17-4 PH | Stainless steel 17-4 (CNC) - SAE grade 630 - is a precipitation hardening alloy with good corrosion resistance. Can be hardened up to 44 HRC. |
| Stainless steel 416 | Stainless steel 416 is magnetic and has a high machinability. |
| Stainless steel 2205 Duplex | Stainless steel 2205 Duplex (CNC) is the alloy with the highest strength and hardness. Suitable for applications in severe environments up to 300°C. |
| Stainless steel 420 | Stainless steel 420 provides high strength and corrosion resistance. It is the hardest of all stainless steels when hardened. |
| Stainless steel 440C | Stainless steel 440C has improved toughness and corrosion resistance due to Carbon and Chromium content. |
| Stainless steel 430 | Stainless steel 430 is magnetic and corrosion resistant. |
| Stainless steel 301 | Stainless steel 301 is corrosion resistant similar to Stainless steel 304. |
| Stainless steel 15-5 | Stainless steel 15-5 has a higher toughness than 17-4, better corrosion resistance and transverse properties compared to other similar martensitic grades. |

FAQ's
1. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
When no specific fillet radius is outlined in the 3D model or drawing, the machinist will incorporate
fillet radii at their discretion to optimize for easy machining. In instances where a particular fillet
radius is needed, explicit specification is encouraged. As a rule of thumb, consider internal vertical
edge radii exceeding 1/3 of the depth, while internal horizontal edges may either remain sharp or
be introduced with a radius ranging from 0.5mm to 1mm.
