Rounding with G642
Rounding with axial tolerances is activated modally
by means of G642. Rounding does not take place
within a defined ADIS area, instead it ensures the
axial tolerances set in MD 33100:
COMPRESS_POS_TOL are adhered to.
The rest of the functionality is identical with G641.

Supplementary conditions
The path reference set is of no importance with
•
linear and circular interpolation,
•
in thread blocks and
•
if all path axes are contained in FGROUP.
Activation
The path reference for the axes that are not contained in
FGROUP is set via the two language commands SPATH
and UPATH contained in the 45th G code group. The
commands are modal. If SPATH is active, the axes are
traversed synchronized with the path; if UPATH is active,
traversal is synchronized with the curve parameter.
