General conditions
Scaling frames
Scaling frames affect programmed tolerances in the same way as axis positions; in other
words, the relative tolerance remains the same.

8.8 Programmable contour/orientation tolerance (CTOL, OTOL, ATOL)
Command for programming an axis-specific tolerance
is valid for:
ATOL
• All compressor functions
• ORISON orientation smoothing
• All rounding types except G641, G644, OSD
: Name of the axis for which an axis tolerance is to be programmed
<axis>
: The value for the axis tolerance will be specified as a length or an
<value>
angle dependent on the axis type (linear or rotary axis).

Comment
; Activate COMPCAD compressor function.
; The machine and setting data is applied here.
; A contour tolerance of 0.02 mm is applied
starting from here.
; A contour tolerance of 0.005 mm is applied
starting from here.
; The machine and setting data is applied again
starting from here.
