The next consideration in what is beginning to feel a bit like a mile long list is your cost. CNC cutting has not traditionally been thought of as the “lowest cost” manufacturing process, but, depending on the situation it can be.
Part nesting: One such instance where CNC cutting can reduce costs is through part nesting. If your part design can be nested in such a way that CNC cutting allows us to produce more parts from the same size sheet of material, then it can reduce material costs significantly.
Small volumes: Because there are no hard tooling costs with CNC cutting, if volumes are low enough, it can be cheaper to produce your parts with digital cutting than die cutting (where there is the additional hard tooling cost to build the die).
Changing designs: During rapid prototyping, design changes are happening frequently. CNC cutting allows a lot of flexibility to update and adjust the part design to be able to quickly test variations in the design. You also won’t have to pay hard tooling each time there is a change to the design.
