MD33100 $MA_COMPRESS_POS_TOL (maximum deviation with compression)

20171 SURF_BLOCK_PATH_LIMIT
mm Maximum traverse length of an NC block for the COMPSURF
function
-
- -
Description:
The machine data defines the maximum traverse length of a block that is still regarded
as compressible. Longer blocks interrupt the smoothing and are traversed normally.
If the value 0 is entered, then the maximum traverse length in the control is
determined by the specified tolerance.

Description:
The value indicates the maximum permissible deviation for the compression for the path
feedrate. The larger the value, the more short blocks can be compressed into one long
block. The maximum number of compressible blocks is limited by the size of the spline
buffer.
In this way, the the compressors COMPON and COMPCURV may limit the compression of the
path axes.
Compressor COMPCAD acts differently: It ignores changes to the F word as long as they
lie below the threshold defined by COMPRESS_VELO_TOL. If the feed programmed in a
block changes more than COMPRESS_VELO_TOL, COMPCAD interrupts the compression at this
block transition so that the feed change takes place at exactly the desired position.
