Compensation with correction table when measuring with rotating spindle

When measuring tools with a rotating spindle, the measuring precision can be compensated
for by additional compensation values during measurement of the cutter radius or cutter
length. These compensation values are stored in tables in the dependency peripheral speed
/ cutter radius. Users can also create their own compensation values in dedicated tables in
data block GUD6.
This offset is activated with variable of data type INTEGER _MT_COMP >0.
_MT_COMP= 0:
_MT_COMP= 1:
_MT_COMP= 2:
Preproduced compensation tables of some tool probe models can be activated using
variables of the data type INTEGER _TP_CF:
_TP_CF= 0:
_TP_CF= 1:
_TP_CF= 2:
The user can enter his own compensation values in two arrays of data type REAL:
• _MT_EC_R[6,5] for radius measurements and
• _MT_EC_L[6,5] for length measurements.
