As the high-mix, low-volume manufacturing supplier of more than a decade experience, we’d like to share design tips which will make your parts easy for machining. In return, you will get parts with short lead time, high precision and higher quality! The structure of the part to be CNC machined should be easy for the tools to cut in and out correctly. This is to cut the tools changing times, improve the working efficiency, and reduce the manufacturing cost.
In original design, the hole is too close to the vertical wall of the part, which interferes the drill chuck. Only the non-standard extended tool can be used, but the rigidity of the tool is poor. While in optimal design, the space is bigger, where standard tool can be used to ensure the manufacturing precision.
When gear shaping, leave undercut, so that the big gear can hobbing or shaping, and the small gear can shaping.
When planing, there must be enough space for the tools back-off at the front end of the plane, so that the tools can be moved.
When grinding, the transition part between the surfaces should save the grinding undercut to facilitate the tools working.
