Combined programming
With the channel parameter [1]-42 the exclusive programming of dimensioning for coordinates of path axes can be disabled. Then it is possible to use absolute and incremental dimensioning in the same NC block. Also the repeated use of G90 and G91 in the same NC block is allowed. In this case the position of G90/G91 inside the NC block has a meaning. The dimensioning programmed last is valid for all following axis positions and for all further NC blocks until the next G90/G91.
Programming example
:
N10 X10 Y10 (Absolute dimensioning G90 is selected, Default)
N20 G91 X20 G90 Y20 (Relative for X axis, absolute fr Y axis)
N30 X30 G91 Y30 Z20 (Absolute for X axis, relativ für Y/Z axes)
N30 G90 X30 G91 Y30 G90 Z20 (Absolute for X/Z axes, relative for Y axis)
:
N100 G90 G91 Z30 (Relative for Z axis)
N110 G91 X10 G90 Z30 (Relative for X axis, absolute for Z axis)
![]() | G90/G91 has no influence on the parameters I, J, K of circular or helical interpolation. Its dimensioning system is defined exclusively by G161/G162. |
