Machine parameter monitoring method for machine tool numerical control

摘要

The machine parameter monitoring method provides redundant monitoring of the machine operating parameters using the 2 redundant processors (MCU,CCU) used for the machine tool numerical control, each providing a check sum (CRC1,CRC2) from the monitored parameters, compared with the previously calculated check sums obtained from a memory, for initiating a fault procedure or halting the operation of the machine tool. An Independent claim for a machine parameter monitoring circuit for a machine tool numerical control is also provided.
