When computer numerical control (CNC) machining parts, it is often desirable to create parts with a fine or smooth surface finish. This becomes even more important when machining for the mold-making or die-making industries. This class will provide tips and strategies for getting the highest-quality surface finishes from your CNC machining. Some areas of discussion will include tooling and holders for maximum rigidity, mill and control parameters to check for optimum surface finish, CAM (computer-aided manufacturing) software parameters and strategies that lead to better finishes, and milling tolerance and point distribution. This class is designed to capture the best practices for the industry, and would be applicable whichever CAM product you are using, such as Delcam’s PowerMILL and FeatureCAM software, HSMWorks add-in, Inventor HSM software, or Fusion 360 software. This session features PowerMill and FeatureCAM.
