Form compensation option launched by NUM for NUMROTO tool grinding software

NUM has launched a powerful form compensation option for its renowned NUMROTO tool grinding software. The new option enables tool manufacturers to “close the loop” between CNC tool grinding and measurement, in order to further increase process accuracy and consistency. The system inherently compensates for process variables such as temperature fluctuations and grinding wheel wear, and is likely to prove especially popular with manufacturers of the latest specialist precision tools, which demand unprecedentedly tight production standards.

Operators seeking to maximise the accuracy of tools produced on CNC grinding machines generally use a coordinate measuring machine (CMM) to obtain probed measurements of the machined part, using this information to influence the production process during subsequent machining operations. Until now, NUMROTO users processed the results from the CMM with proprietary third-party compensation software running on an external computer, before feeding a suitably corrected target profile back into the CNC machine.
