Tool programming
The designations of the tool pockets are fixed by the machine tool
builder. Each tool holder has a unique T number.
In the T command (MACHINING section) you program the tool holder,
and therefore the position to which the tool carrier rotates. The CNC
PILOT retrieves the assignment of the tools to the tilted position from
the TURRET section, or the tool list (in case the T number is not
defined in TURRET).
Multipoint tools: A multipoint tool is a tool with more than one
cutting edge. During T call, the T number is followed by an S to identify
the cutting edge.
T number.S (S=0 to 4)
S=0 identifies the main cutting edge, which does not need to be
programmed. In the TURRET section, you define only the main cutting
edge.
When a cutting edge of a multipoint tool has become dull, the tool life
management function marks all cutting edges as worn-out.
Examples:
„ T3 or T3.0: Tilted position 3; main cutting edge
„ T12.2: Tilted position 12; cutting edge 2
Replacement tools: If you use the tool life monitoring, you define a
sequence of exchange. As soon as a tool is worn out, the CNC PILOT
inserts a replacement tool. The CNC PILOT does not stop the program
run until the last tool of the tool sequence of exchange is worn out.
In the TURRET section and the T commands, you program the first
tool to be changed. The CNC PILOT automatically inserts the
replacement tool. When programming variables (access to tool
compensation or tool diagnosis bits), you also address the first tool of
the sequence. The CNC PILOT automatically addresses the active
tool.
You can define replacement tools in “Setup.”
