FIVE-AXIS MACHINING
CNC Control Smoothes, Speeds Five-Axis Machining The Mazatrol SmoothX CNC technology introduced by Mazak Corp. (Florence, KY) at IMTS 2014 is part of a com- plete process performance technology platform that reaches across the entire part production cycle from programming to metal removal to automation and data collection. The technology comprises, in addition to the SmoothX CNC, new machine hardware and servo systems. Working together they are designed to tackle real machining challenges including cycle times, especially for simultaneous five-axis operations and free-form die-mold machining. “We have run a five-axis machine with the previous generation Matrix 2 CNC five-axis code and then with the SmoothX CNC, and have seen drastic improvements just in the machine’s ability to interpolate code and send it to the machine tool servos in the shortest time,” said Michael Finn, development engineer. “The ability to read code at a higher rate is especially important in machining complex geom- etries like turbine blades, blisks, or any free-form surface that requires a higher point density,” said Finn. To overcome the tendency of five-axis machining to be slower with longer cycle times, the Mazatrol SmoothX CNC ability to read code faster allows maintaining chip load in complex surface machining. “You need higher point density, where the machine changes direction and those are typi- cally the leading and trailing edges on the blade. That’s where a lot of data points are required to keep the tool on track maintaining chip load so that it doesn’t fall away or gouge the workpiece. It’s important to have a CAM system that can prove-out programs with toolpath verification and collision avoidance. In the SmoothX CNC, you simply click on the area of the toolpath and it will highlight the code that applies, giving the user another important tool in his tool box,” said Finn.
