<p>Control of a CNC machine is interfaced with a PC (20) to make information relative to the block number, feed-rate and/or spindle speed over-ride values available at the personal computer (20). Operator will manually over-ride the feed-rate and/or the spindle speed to optimize machining performance. Through the use of modules, the spindle speed and feed-rate controls (16 and 18) are polled at frequent intervals. The status or over-ridden values of these controls (16 and 18) are correlated to the active block number in use during each polled sequence and this information is written to an 'event file' (13 and 15). After the subject part (12) has been completed, one of two options can be used. An 'edit phase' is initiated which utilizes the information in the 'event file' (13 and 15) to reconstruct the MCD file (13 and 15). After the edit phase is complete, the output 'optimized MCD' (13 and 15) can be used to produce like parts (12).</p> |
