Move Tool into Position ‘MTP’
The MTP command initiates a tool storage move which places the tool
selected via the T-word in the NC-program in the specified position
(change, installation or processing position).
MTP
MTP(<Position[1..4]>)
MTP(3)
MTP(<Position[1..4]>,<Direction[0..2]>)
MTP(1,2)
MTP(<Variable>,<Variable>)
MTP(@110,@90)
Position = 1: move selected tool to change position 1
Position = 2: move selected tool to change position 2
Position = 3: move selected tool to change position 3
Position = 4: move selected tool to change position 4
Direction = 0: any given direction
Direction = 1: positive direction
Direction = 2: negative directing
Optionally, the position into which the selected tool is to be brought and
the direction to be taken when the tool is moved to the specified change
position can also be declared. If no direction or position is stated, tool
management selects the shortest distance and change position 1.
If a number of tools having the name ID and the same T-number are lo-
cated in the tool storage unit—so-called spare tools—the tool which has
the status of process/machining, p tool is automatically selected by tool
management.
With machines which have a tool magazine that can be pre-positioned
during processing, the MTP command is often used to pre-rotate the
magazine. MTP is usually programmed together with tool selection T... in
the NC-program immediately after the change of the previously required
tool. In this way, the next tool is already moved to the tool change position
while machining work continues.
This command is used in particular on tool changers which have double-
arm grippers when the previous tool is to be placed in the magazine
pocket from which the new tool is being taken.
•
Like MFP the T0 MTP command moves the next free pocket into posi-
tion.
•
The CNC does not wait until the tool storage unit has completed its
motion. It continues to process the NC-program while the move is be-
ing carried out. If this is not desirable, the MRY command tool storage
ready? can be used to halt execution of the NC-program until the tool
storage motion is completed.
