TLFRn
This variable allows the value corresponding to the real life of the indicated tool (n) to be read or
modified in the tool table.
TMZTn
This variable allows the contents of the indicated position (n) to be read or modified in the tool
magazine table.
HTOR
The HTOR variable indicates the tool radius being used by the CNC to do the calculations.
Being a variable that can be read and written by the CNC and read-only from the PLC and DNC,
its value may be different from the one assigned in the table (TOR).
On power-up, after a T function, after a RESET or after an M30 function, it assumes the value of
the table (TOR).
Application example
To machine a profile with a residual stock of 0.5 mm running 0.1mm-passes with a tool whose radius
is 10 mm.
Assign to the tool radius the value of:
10.5 mm in the table and execute the profile.
10,4 mm in the table and execute the profile.
10,3 mm in the table and execute the profile.
10,2 mm in the table and execute the profile.
10,1 mm in the table and execute the profile.
10,0 mm in the table and execute the profile.
However, if while machining, the program is interrupted or a reset occurs, the table assumes the
radius value assigned in that instant (e.g.: 10.2 mm). Its value has changed.
To avoid this, instead of modifying the tool radius in the (TOR) table, use the variable (HTOR) to
change the tool radius value used by the CNC to calculate.
Now, if the program is interrupted, the tool radius value initially assigned in the (TOR) table will be
correct because it has not changed.
Read-and-write variables of the mill model CNC
TORn
This variable allows the value assigned to the radius of the indicated tool offset (n) in the tool offset
table to be read or modified.
TOLn
This variable allows the value assigned to the length of the indicated tool offset (n) to be read or
modified in the tool offset table.
TOIn
This variable allows the value assigned to the wear in radius (I) of the indicated tool offset (n) to be
read or modified in the tool offset table.
CNCRD(TOR3,R100,M102);
Assigns the R value of tool offset 3 to register R100.
CNCWR(R101,TOR3,M101)
Assigns the value indicated in R101 to the radius of tool offset 3.
