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.

Information
Depending on the default setting you have chosen, the control system interprets all
geometric values as either metric or inch dimensions. Tool offsets and settable zero offsets
including their displays are also to be understood as geometrical values; this also applies to
the feed F in mm/min or inch/min.
The default setting can be set in machine data.
All examples provided in this Manual assume the metric default setting.
G70 or G71 evaluates all geometric parameters that directly refer to the workpiece, either as
inches or metric units, for example:
●
Positional data X, Z, ... for G0,G1,G2,G3,G33, CIP, CT
●
Interpolation parameters I, K (also thread pitch)
●
Circle radius CR
●
Programmable work offset (TRANS, ATRANS)
All remaining geometric parameters that are not direct workpiece parameters, such as
feedrates, tool offsets, and settable work offsets, are not affected by G70/G71.
