Performance-specified machining is a new capability that allows machine operators to choose appropriate levels of speed and accuracy required during any phase of a part program, using a sliding scale. For example,

the operator might opt for increased speed during the initial roughing passes then adjust to increased accuracy for the surface finishing passes. Performance-specified machining actually retunes the servo gains, PID loops and other parameters that would take considerable time to do manually, if the operator were capable of doing it at all.

And while older controls may require the machine to be idled or off while new servo parameters are dialed in, the next-generation controls give the operator direct access to the line of code to choose exact levels of performance desired, on the fly and without disruption. Setup of the basic servo parameters at machine startup is automatic and 100 percent accurate with software technology that identifies all hardware at startup and populates the CNC with the needed data, eliminating any potential for operator errors.
