Numerical Control Computer Sciences (NCCS, Newport Beach, Calif.) has added several new features to its numerical control (NC) software, designed to improve machine simulation and verification. Two of the new features, NCL and NCL/IPV, now support tool motion verification, using a machine control data (MCD) file as input. This method of generating tool paths reportedly improves part quality and efficiency. Also, using the company’s PTED routine, the MCD file is automatically reverse postprocessed, creating a machine simulation file that is read as input to the verification routine. This is said to save time by simulating complex programs before they are sent to the machine.
