8.3 Tool selection/tool call T
8.3.1 Tool change with T commands (turning)
Function
A direct tool change takes place when the T word is programmed.
Tool selection without tool management
Free selection of D No. (flat D No.) relative to cutting edges
Tabulated D No.: D1 ... D8
Tool selection with tool management
Free selection of D No. (flat D No.) relative to cutting edges
Fixed assignment of D No. to the cutting edges
Programming
Tx or T=x or Ty=X
Or
T0=
Parameters
Tx or T=x or Ty=x
Tool selection with T No. including tool change
(active tool), tool offset is active
x
x stands for T No.: 0-32000
T0=
Tool deselection
Number of tools: 1200
(depending on the machine manufacturer's configuration)

The effect of the T number call is defined in machine data. See machine manufacturer's
configuration.
Important
It is important to ensure that the machine data for "Error response for programmed tool
change" is expanded by bit 7.
• With the currently valid default setting
, a check is performed immediately to ascertain whether the NC kernel is aware of the
tool number. If not, an alarm is triggered immediately.
• A response that deviates from this (default setting for previous software versions) can be
brought into line with bit 7.
The programmed tool number will only be checked following D-selection. If the NC kernel
is unaware of the tool number, an alarm is set during D-selection. This response is
