b'Catching 22MO Series Monitoring Adaptive Control from Caron Engineering Inc., Wells, Maine. TMAC monitors the spindle drive, and an increase in power indicates tool wear, said Pres-Spindle Speeders ident Rob Caron. We also do adaptive control, so we can take over the feed rate and achieve a constant power cut by modifying the feed rate in real time.He explained that the system monitors true power instead of current to provide a more linear signal over the range of the spindle motor load and function as a more accurate indicator.If the motor is lightly loaded, with current you dont get a very linear signal or a very good representation of what is going on, Caron said. Its much better when the motor is heavily loaded. By monitoring true power, your signal is absolutely linear whether you are monitor-ing a light cut or a heavy cut.By continuously monitoring the power drive, the sys-tem reduces the feed rate only when a cutting tool starts to load up or degrade or when the material thick-ness or hardness increases, Caron said. So when-ever we can go faster, we will, whereas without the sys-tem the customer has to program basically worst-case 46JULY 2019 Titanium.indd 46 6/17/19 10:30 AM'
