come smaller and portable enough to be located adjacent to the machining center.
In contrast, the CAPPSNC on-machine measurement system from Applied Automation Technologies (www.aat3d. com) provides capabilities to quickly develop measurement programs offline and run these programs directly on CNC machine tools in a similar fashion to a CMM. Offline pro- gramming with virtual machine models and the use of CAD part models allow the machine tool itself to be programmed to perform complex measurement and reporting tasks, in- cluding multi-datum profile and true position analysis.
Users taking advantage of these programs with our work offset option are no longer restricted to using standard macros to identify only the most basic geometry as machining coor- dinate locations. Using CAPPSNC alignments, complex 3D features, intersections, tooling balls, and best-fit alignments pick up work offsets. Part setups are both faster and more ac- curate, saving time and money.
Realistic program simulations, collision avoidance, and optimum measurement path generation for multiple geomet- ric features makes it very easy to program and make changes for any type of machine-tool configuration. This ultimately enables a very easy method of quickly generating metrology data directly at the production source.
CAPPSNC – Software and Hardware
The CAPPSNC system connects with the machine tool with an ethernet cable and can read and write to any con- troller parameter. The data generated with CAPPSNC’s on- machine measurements is not only valuable for part veri- fication—the goal here is not to make stand-alone CNNs obsolete. Rather, it’s to use the data—immediately, as soon as it is generated—to improve the machining process by ad- justing various machining parameters such as work offsets and tool offsets.
One reason it can do so is because the CAPPSNC system works as a variation of Edge Computing: The data need not travel away from where it is generated in order to be pro- cessed and used to improve machining quality. In fact, it’s a secure closed-loop system — everything happens on the machine tool and its controller.
Error detection, diagnosis, and compensation all hap- pen where the error occurred—and quickly. Periodic health checks throughout each shift enable greater machine con- sistency, which yields more good parts, which lowers pro- duction costs while improving throughput. Networking such Smart Machining data throughout a facility makes such im- provements possible on all your production equipment.
