Dimensions Inch/Metric, (G70/G700, G71/G710) - Siemens SINUMERIK 840DE Programming Manual

Positional Data

3.4 Dimensions inch/metric, (G70/G700, G71/G710)

All of the commands are non-modal.
You can also use DC, ACP and ACN for spindle positioning from zero speed.
Example: SPOS=DC(45)
3.4 Dimensions inch/metric, (G70/G700, G71/G710)
Function
Depending on the dimensions in the production drawing, you can program workpiece
geometries alternately in metric measurements and inches.

G700/G710
The functionality of G70/G71 has been extended with G700/G710. In addition to the
geometrical parameters, the technological parameters, such as feed F, are interpreted
during parts program execution in the system of units set in G700/G710.
The controller interprets all feedrates used with G700/G710 in the programmed system of
units, unlike G70/G71.
The programmed feedrate value is modal and thus does not change automatically on
subsequent G70/G71/G700/G710 selections.
Example of milling
Change between metric and imperial input with basic setting metric (G70/G71).
