alignments in nc
hi jan
with nc the concet of alignments is slightly different than traditional live cmm measurement.
you still have to create your pc-dmis part program as normal whilst remembering that in general terms the co-ordinate system of the machine tool will not change throughout the measurement program. this means that even though you might have more than one local alignment in your measuring program they will be ignored when posting out the g-code program.
what happens is that all the features get measured according to the machine tool alignment (co-ord system, for examle g54) and when the data comes back to pc-dmis for analysis, this is when it gets transformed to the alignments you have chosen in your program.
so, to answer the question there won't be any change in the g-code that gets produced whether or not you have alignments in the pc-dmis rogram. all that happens is that if you do have alignments in the program the data will be transformed as and when analysis takes lace.
thanks, cdmisnc.
