User tool data
Additional machine data sets are introduced for user-defined tool data:
MD18094 $MN_MM_NUM_CC_TDA_PARAM
and cutting edge data:
MD18096 $MN_MM_NUM_CC_TOA_PARAM:
MD10290 $MN_CC_TDA_PARAM_UNIT [MM_NUM_CC_TDA_PARAM]
MD10292 $MN_CC_TOA_PARAM_UNIT [MM_NUM_CC_TOA_PARAM]
A physical unit can be configured using these machine data. All lengthrelated userdefined
tool data are automatically converted to the new measuring system according to the input on
switchover.
Reference point
The reference point is retained. It is not necessary to repeat referencing.
Input resolution and computational resolution
The input/computational resolution is set in the control via machine data:
MD10200 $MN_INT_INCR_PER_MM.
Default settings:
Metric system Inch system
1000 (0.001 mm) 0.0001
Example:
1 inch = 25.4 mm ⇒ 0.0001 inch = 0.00254 mm = 2.54 μm
To be able to program and display the last 40 mm, MD10200 must be assigned a value of
100000.
Only with this identical setting for both measuring systems is it possible to change the
measuring system without a significant loss of accuracy. Once MD10200 has been set to this
value, it will not need to be changed each time the measuring system is switched over.
