Depending on the measuring system used in the production drawing, it is possible to program workpiece-related geometrical data in either metric units (G71) or inches (G70). The CNC is set to a basic system regardless of the dimension system that has been programmed.
The following geometrical data can be entered directly and converted by the CNC into the other measuring system (examples):
Position data X, Y, Z, etc.
Interpolation parameters I, J, K and circle radius CR
Thread pitch
Programmable work offset (TRANS)
Polar radius RP
With the G700/G710 programming expansion, all feedrates are also interpreted in the programmed measuring system (inch/min or mm/min). In the Machine operating area, the operator can switch back and forth between inch and metric dimensions using a softkey.
