18.2 Tool
18.2.1 General
Select tool
A tool is selected in the program with the T function.
Whether the new tool will be loaded immediately by means of the T function depends on the setting in the
machine data:
$MC_TOOL_CHANGE_MODE (new tool compensation with M function) determines whether the new tool is
loaded immediately on execution of the T function.
Change tool immediately
MD22550 $MC_TOOL_CHANGE_MODE = 0 (new tool compensation with M function).
The new tool is changed immediately with the T function.
This setting is used mainly for turning machines with tool revolver.
Change tool with M06
MD22550 $MC_TOOL_CHANGE_MODE = 1 (new tool compensation with M function).
The new tool is prepared for changing with 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 old tool is removed from the spindle and the new tool is loaded into the spindle with the entered M function in
the machine data:
MD22560 $MC_TOOL_CHANGE_M_CODE (M function for tool change)
This tool change must be programmed with the M function M06, in accordance with DIN 66025.
The next tool is preselected with the machine data:
MD20121 $MC_TOOL_PRESEL_RESET_VALUE (Preselected tool at RESET)
Its tool length compensation values must be considered at RESET and powerup according to machine data:
MD20110 $MC_RESET_MODE_MASK (Determination of control default settings after RESET/TP end).
Value range of T
The T function accepts the following whole numbers:
•From T0 (no tool)
•To T32000 (tool number 32000).
