Machine data
3.3 Channel-specific machine data
20202 WAB_MAXNUM_DUMMY_BLOCKS
- Maximum number of blocks w/o traversing movement with SAR
-
- -
Description:
Maximum number of blocks which can appear between the SAR (soft approach and
retraction) block and the traversing block which determines the direction of the
approach or retraction tangent.
20204 WAB_CLEARANCE_TOLERANCE
mm Change of direction with SAR
-
- -
Description:
In the case of smooth approach and retraction, the point defined with DISCL, from
which, in the case of infeed from the initial plane, traversing is carried out at lower
speed (G341) or the point in which the actual approach movement begins (G 340), must
lie between the initial plane and the approach plane.
If this point lies outside this interval and the deviation is less than or equal to
this machine data, it is assumed that the point lies in the approach or retraction
plane.
If the deviation is greater, then alarm 10741 is output.
Example:
An approach is made from position Z = 20. The SAR plane is at Z = 0. The point defined
by DISCL must therefore lie between these two values. If it lies between 20.000 and
20.010 or between 0 and -0.010, it is assumed that the value 20.0 or 0.0 was programmed
(under the condition that the MD has the value 0.010). The alarm is output if the
position is greater than 20.010 or less than -0.010.
20256 CUTCOM_INTERS_POLY_ENABLE
- Intersection procedure for polynomials is possible
-
- -
Description:
If this machine data is TRUE and tool radius compensation active, the transitions at
outer corners where polynomes (splines) are involved can be treated with the
intersection mode. If the machine data is FALSE, conic sections (circles) are always
inserted in this case.
If the machine data is FALSE, the response is identical to that of software releases
older than 4.0.
20270 CUTTING_EDGE_DEFAULT
- Initial position of tool cutting edge without programming
-
- -
Description:
Default cutting edge after tool change
If no cutting edge has been programmed after a tool change, the default cutting edge
number set in MD20270 $MC_CUTTING_EDGE_DEFAULT is used.
Value
:= 0
Initially, no cutting edge is active after a tool change.
The cutting edge is not selected until D programming.
