A new capability enables CAM software to establish a performance baseline for a specific machine, and use that information to create a personalized, optimized tool path.

This atypical tool path is highly flavored by the individual characteristics
of the specific machine that will run the job.
A conventional CAM-generated tool path is generic. That is to say, it can be used to drive pretty much any suitable CNC machine once the appropriate postprocessor is written. There is a point, though, at which the operational limits of a machine and its control come into play. For instance, a machine simply might not have the ability to maintain the programmed feed rate that would otherwise result in optimal performance. In addition, controls differ in terms of their processing speed, high speed machining parameters and method for handling arc/line transitions among other characteristics. This spurred Delcam to look more closely at how the differences between individual machines, even machines that are very similar, affect the overall speed and effectiveness of a CAM-generated tool path.
The result of these efforts is MachineDNA, a technology the company developed more or less concurrently with its new Vortex controlled engagement angle roughing strategy designed for solid carbide tools. Directly integrated into a CAM system such as PowerMill, MachineDNA enables the CAM system to gather data from a specific machine to establish a performance baseline and use that information to create an individualized tool path shaped by the machine’s condition and capabilities. By learning and applying a machine’s own traits, different, yet effective tool paths can result even though the same overall strategy (i.e. controlled engagement angle) is applied. Learn more.
