Dimensions in metric units and inches: G71, G70, G710, G700
Functionality
If workpiece dimensions that deviate from the base system settings of the control system 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.
; Inch dimensions, also for feedrate F
; Metric dimensions, also for feedrate F
; metric dimensioning from this point on
Depending on the
you have chosen, the control system interprets all geometric values as either metric
inch dimensions. Tool offsets and settable work 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
G70 or G71 evaluates all geometrical data that directly refer to the
, 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 lead)
● Circle radius CR
●
work offset (TRANS, ATRANS)
All remaining geometric parameters that are not direct workpiece parameters, such as feedrates, tool offsets, and
work offsets, are not affected by
.
,
however, also affects the feedrate F (inch/min, inch/rev. or mm/min, mm/rev.).
Radius/diameter dimensions: DIAMOF, DIAMON, DIAM90
Functionality
For machining parts, the positional data for the
(transverse axis) is programmed as diameter dimensioning. When
necessary, it is possible to switch to radius dimensioning in the program.
DIAMOF or DIAMON assesses the end point specification for the X axis as radius or diameter dimensioning. The actual
value appears in the display accordingly for the workpiece coordinate system.
For DIAM90, irrespective of the traversing method (G90/G91), the actual value of the transverse axis is always displayed as
a diameter. This also applies to reading of actual values in the workpiece coordinate system with MEAS, MEAW, $P_EP[x]
and $AA_IW[x].
