cnc machining surface finishing I'm having a heck of a time achieving a good surface finish on some 3D surfaced tools steels. I'm machining 4140 PHT, A-2 and D-2. The A-2 and D-2 are soft. I'm finishing with 1/4" and 3/16" 4 flute ball mills. Only 2 flutes are to center. 1/4" is running at 8000 rpm and 60 ipm with a .003" step. What is meant by metal fabrication? Metal fabrication is the processing of metals to create various metal objects. The process of metal fabrication can happen in one step or can even take tens of steps, depending on what is required.

While the CNC fixture holds the workpiece in place, the feed rate impacts the CNC machining surface finish since it increases the number of passes the tool makes over the material. In other words, when the feed rate is high, it often results in a rougher surface finish, while a lower feed rate results in a smoother finish. Understanding the Role of Metal Type. Different types of metals‘ physical and chemical properties are distinct and affect the different finishing operations in varying degrees of effectiveness. For instance, steel, the most common ferrous metal, usually goes through galvanizing in order to prevent screen damage since it rusts very quickly owing to its iron .
