SECTION THREE - CONVERSATIONAL INPUT SCREENS
F5 (TChng) Tool Change
When a new tool needs to be put in the machine tool, the tool change screen should be used. The
two tool change screens are tool call and tool change. The tool call is used to initiate a new set of
tool offsets without physically changing the tool. The tool change puts the machine in a tool
change mode and calls for a new tool. When a tool change or tool call is executed, the H and D
offsets which are activated will be the ones which are the same as the tool number. For safety
reasons, when doing manual tool changes, the machine should always be in a tool change mode.
The tool screens are shown below.
Conversational screen for tool change.
The next tool number field is used for migrating tool changers. The tool holder will index to the
next tool while it cuts with the active tool.
Note: See page 305, Section 5 for further information on tool change.
The conversational screen for tool call appears as follows. No tool change is performed. The tool
offsets are called. The spindle and coolant commands are executed.
When a tool change position is entered, if the Z axis is at or above the tool change position, the
XY move will be executed prior to any Z axis movement. If Z is below the tool change position,
Z will move to the tool change position, and then X and Y will move. If the X and Y number are
not filled in, only Z will move during a tool change.
