CNC machining is another commonly used method in rapid prototyping for steel castings. Instead of producing a casting directly, engineers can machine a prototype component from a solid steel block to verify dimensions, assembly requirements, and functional performance.
CNC machined prototypes provide excellent dimensional accuracy and are suitable for applications where engineers need to test the physical behavior of a component before developing casting processes.
Advantages of CNC machined steel prototypes include:
High dimensional precision
Fast production for simple geometries
Suitable for functional testing
Direct use of production-grade materials
However, CNC machining may become less economical for highly complex geometries because large amounts of material may need to be removed during manufacturing.
