Dimensions In Metric Units And Inches: G71, G70, G710, G700 - Siemens SINUMERIK 802D sl Programming And Operating Manual

G91 applies to all axes and can be deselected in a subsequent block by G90 (absolute
dimensioning).
Specification with =AC(...), =IC(...)
After the end point coordinate, write an equality sign. The value must be specified in round
brackets.
Absolute dimensions are also possible for circle center points using =AC(...). Otherwise, the
reference point for the circle center is the circle starting point.
Programming example
N10 G90 X20 Z90
N20 X75 Z=IC(-32)
...
N180 G91 X40 Z20
N190 X-12 Z=AC(17)

Dimensions in metric units and inches: G71, G70, G710, G700

Functionality
If workpiece dimensions that deviate from the base system settings of the control are present
(inch or mm), the dimensions can be entered directly in the program. The required
conversion into the base system is performed by the control system.
