Overview of typical dimensions
The basis of most NC programs is a drawing with concrete dimensions.
When implementing in a NC program, it is helpful to take over exactly the dimensions of a
workpiece drawing into the machining program. These can be:
● Absolute dimension, G90 modally effective applies for all axes in the block, up to
revocation by G91 in a following block.
● Absolute dimension, X=AC(value) only this value applies only for the stated axis and is
not influenced by G90/G91. This is possible for all axes and also for SPOS, SPOSA
spindle positionings, and interpolation parameters I, J, K.
● Absolute dimension, X=CC(value) directly approaching the position by the shortest route,
only this value applies only for the stated rotary axis and is not influenced by G90/G91. Is
also possible for SPOS, SPOSA spindle positionings.
● Absolute dimension, X=ACP(value) approaching the position in positive direction, only
this value is set only for the rotary axis, the range of which is set to 0... < 360 degrees in
the machine data.
● Absolute dimension, X=ACN(value) approaching the position in negative direction, only
this value is set only for the rotary axis, the range of which is set to 0... < 360 degrees in
the machine data.
● Incremental dimension, G91 modally effective applies for all axes in the block, until it is
revoked by G90 in a following block.
● Incremental dimension, X=IC(value) only this value applies exclusively for the stated axis
and is not influenced by G90/G91. This is possible for all axes and also for SPOS,
SPOSA spindle positionings, and interpolation parameters I, J, K.
● Inch dimension, G70 applies for all linear axes in the block, until revoked by G71 in a
following block.
● Metric dimension, G71 applies for all linear axes in the block, until revoked by G70 in a
following block.
● Inch dimension as for G70, but applies also for feedrate and length-related setting data.
● Metric dimension as for G71, but applies also for feedrate and length-related setting data.
