The physical placement correspoding to the WCS (Working Coordinate System) specified in the HSMWorks jobs is determined on the CNC machine and stored in the machine offset table. The job setup sheet provides the operator with the required information to setup the CNC. The NC program generated by the HSMWorks post processor must reference the correct zero point entry in which the measured placement is stored. For ISO controls the zero points are commonly referenced in the NC program using the G-codes G54, G55 and so on but controls vary greatly in this regard.
It is the responsibility of the post processor to output the correct zero point references. The individual post processor customizations are free to derive the desired zero point references in any way they choose and can for instance be hardcoded or derived from various user-specified parameters.
