assigned. The D numbers of all tools defined within a TO unit may not occur more than once.

No allowance is made for replacement tools.

CHKDNO(Tno1)

You must assign unique D numbers. Two different cutting edges of a tool must not have the

same D number.

This command returns the D number of a particular cutting edge (ce) of a tool with tool

number t. If no D number exists for the entered parameters, d=0 will be set. If the D number

is invalid, a value greater than 32000 is returned.

This command assigns the value d of the D number to a cutting edge ce of tool t. The result

of this statement is returned via state (TRUE or FALSE). If there is no data block for the

specified parameter, the value FALSE is returned. Syntax errors generate an alarm. The D

number cannot be set explicitly to 0.

d = GETDNO (t,ce)

state = SETDNO (t,ce,d)

All D numbers of the part specified are checked.

All D numbers of Tno1 are checked against all other tools.

All D numbers of all tools are checked against all other tools.

7.7 Free assignment of D numbers, cutting edge numbers

The D numbers are assigned uniquely to the

checked areas.

There was a D number collision or the parameters

are invalid. Tno1, Tno2 and Dno return the para-

meters that caused the collision. These data can

now be evaluated in the part program.
