Description:
The T function is used to select a tool in the program. The setting in this
machine data determines whether the new tool is loaded immediately on execu-
tion of the T function:
MD22550 $MC_TOOL_CHANGE_MODE = 0
The new tool is loaded directly with the programming of T or D. This setting
is mainly used on turning machines. If a D is not programmed in the block by
T, then the tool offset defined in MD20270 $MC_CUTTING_EDGE_DEFAULT is
active.
In this case, the function "Manual tools" is not enabled.
MD22550 $MC_TOOL_CHANGE_MODE = 1
The new tool is prepared for loading on execution of the T function. This
setting is used mainly on milling machines with a tool magazine in order to
bring the new tool into the tool change position without interrupting the
machining process. The M function entered in MD22560 $MC_ TOOL_CHANGE_M_CODE
is used to remove the old tool from the spindle and load the new tool onto
the spindle. According to DIN 66025, this tool change has to be programmed
with M function M06.

MD22560 $MC_TOOL_CHANGE_M_CODE
Description: If the T function is only used to prepare a new tool for a tool change (this
setting is used mainly on milling machines with a tool magazine, in order to
bring the new tool into the tool change position without interrupting the
machining process), another M function must be used to trigger the tool
change.
The M function entered in TOOL_CHANGE_M_CODE triggers the tool change (remove
old tool from the spindle and load new tool into the spindle). This tool
change is required to be programmed with M function M06, in accordance with
DIN 66025.
