8.8 Programmable contour/orientation tolerance (CTOL, OTOL, ATOL)
Function
The CTOL, OTOL, and ATOL commands can be used to adapt the machining tolerances defined
for the compressor functions (COMPON, COMPCURV, COMPCAD), the smoothing types
G642, G643, G645, OST, and the orientation ORISON using machine and setting data in the
NC program.
The programmed values are valid until they are reprogrammed or deleted by means of the
assignment of a negative value. They are also deleted at the end of a program, in the event
of a channel reset, a mode group reset, an NCK reset (warm restart), and POWER ON (cold
restart). On deletion of these values, the values from the machine and setting data are
restored.
Syntax
CTOL=<value>
OTOL=<value>
ATOL[<axis>]=<value>
Significance
Command for programming the contour tolerance
CTOL is valid for:
• All compressor functions
• All rounding types except G641 and G644
The value for the contour tolerance is specified as a length.
Type: REAL
CTOL
<value>:
Unit: inch/mm (dependent on the current dimensions setting)
Command for programming the orientation tolerance
OTOL is valid for:
• All compressor functions
• ORISON orientation smoothing
• All rounding types except G641, G644, OSD
The value for the orientation tolerance is specified as an angle.
Type: REAL
OTOL
<value>:
Unit: degrees
