The following differences exist between PC-DMIS NC and PC-DMIS:
PC-DMIS NC does not run interactively with the NC machine. However, PC-DMIS NCI does work interactively (See "PC-DMIS NCI Differences"). PC-DMIS NC creates a stand-alone NC measurement routine file which is executed on the NC controller. Embedded in the NC measurement routine file is all the information NC Gateway server application needs to select the associated PC-DMIS measurement routine. NC Gateway then loads probing data from the NC machine into PC-DMIS NC and executes the selected measurement routine.
PC-DMIS NC version 1.0 typically cannot send data to the NC controller during execution. Controllers shown with NC or NCi in the "PC-DMIS NC: Introduction" topic are capable of updating work offsets, tool offset, and variables in the control. Controllers for which this is not possible are shown with (NC- not interactive).
Probing paths are static and cannot be changed for all NC versions. These paths are generated from the part model's nominal geometry prior to execution. Interactive functions that modify the path during measurement routine execution have been disabled in the PC-DMIS NC menus. Since you create the measurement routine in Offline mode, the path cannot change. For example, you will be unable to modify a path based on a previously measured alignment. PC-DMIS NCi versions operate interactively with PC-DMIS by sending each path point to the control and allowing logic operations to control measurement routine path execution and iterative alignments.
Alignments computed from features will only be used during the analysis phase for NC.
The following topics list different PC-DMIS items as either supported or unsupported in PC-DMIS NC. Where PC-DMIS NCI supports or does not support a particular item, notation is provided. Otherwise, both NC and NCI are both either supported or unsupported. For more information on these specific items, see the PC-DMIS Core documentation.
