Many users of machines with inclined axes require an NC part program which allows non-
perpendicular NC axes to be treated in the same way as perpendicular axes for programming
purposes.
Two different systems of co-ordinates are therefore provided:
• A non-cartesian, real co-ordinate system of machine axes
• A cartesian, simulated co-ordinate system
The GI functionality is so universal in design that the above demand can be satisfied.
This option is explained below using the example of a grinding machine with an inclined axis.
The diagram below shows a plain grinding machine with a U axis inclined in relation to the Z1
axis by an angle of 90°- .
