All CNC machined parts must undergo normal deburring and edge breaking processes. Technical designs must make it obvious if there are any essential edges that should be left sharp. Surfaces will be devoid of minor flaws including hanging marks, scratches, dents, stains, and other flaws. The primary (a) side, as shown on the technical drawing, will be free of mill steps and other marks on the surfaces designated as critical. Small hanging marks and up to two minor flaws are permissible on the secondary (b) side. The surface roughness, aesthetic qualities, and wear resistance of machined parts can all be improved by the use of various post-processing and finishing techniques.

The primary expenses incurred by CNC machining can be divided into four categories: machining time, start-up expenses, material expenses, and feature expenses. You must comprehend how these elements affect prices if you want to lower them.

Designing features that can be machined fast, such as selecting the proper radii for internal corners, decreasing cavity depth, raising wall thicknesses, restricting thread length, and creating holes with uniform diameters, is the greatest strategy to shorten machining times.

By taking into account the size of the blank needed, as well as the price and machinability of the bulk material, material costs can be decreased (softer alloys are faster to machine).

Starting costs can be decreased by cutting down on the number of rotations or repositionings necessary to complete the part, for instance by breaking up geometries into separate sections that can be put together afterwards.

By deleting all text and lettering, employing tolerances only where absolutely essential, and avoiding various surface treatments, feature costs can be brought down.
