8.1.4 Multipoint Tools, Tool Life Monitoring
Multipoint tools
Turning tools with more than one (maximal 5) cutting edges are
referred to as multipoint tools. In the tool database, each cutting
edge is given a tool definition—in addition, the identification
numbers of the cutting edges of a Multipoint tool are linked so that
a sequence is defined which comprises all cutting edges.
Define one of the cutting edges as primary cutting edge and the
other ones as secondary cutting edges. In the tool list, the ID
number of the primary cutting edge (see “
4.2.4 Tool Programming“).
Parameters of 3rd dialog box
Mag(azine) code: Not used at present
Mag(azine) attr(ibute): Not used at present
Multi tool: Multipoint tool
■ No: No Multipoint tool
■ Main: Primary cutting edge
■ Aux.: Secondary cutting edge
M ID: Identification number of the following cutter of a multipoint
tool
Mon(itoring) method of the tool life monitoring function (see
“
4.2.4 Tool Programming“)
■ No
■ Tool life monitoring
■ Quantity monitoring
Tool life total: Tool life of the cutting edge
Tool life rem.: Display of remaining tool life
Quantity total: Total quantity that can be produced by a tool.
Quantity remaining: Display of remaining quantity.
Reason for retiring Displays reason tool has been retired:
■ Tool life expired
■ Quantity reached
■ Tool life expired
■ Determined by in-process measuring
■ Determined through postprocess measurement
■ Tool wear (limit value 1 or 2 of the power has been exceeded)—
detected through load monitoring
■ Tool wear (limit value of “work” exceeded)—determined by load
monitoring
The tool life parameters are reset with a new cutting edge (see
“
3.5.5 Tool Life Management“).
Data input for multipoint tools
Primary cutting edge:
Parameter input (dialog box 1 and 2)
Use the “PgUp” key to switch to dialog box 3
Enter the Main (cutting edge) in the “Multi.
tool” input field
Enter the identification number of the following
secondary cutting edge in the “M ID” input field
Conclude with “OK.”
For each secondary cutting edge:
Enter the identification number (ID number that
has been entered into the “M ID” field for the
preceding cutting edge)
For further parameter input (dialog boxes 1 and 2)
Use the “PgUp” key to switch to dialog box 3
Enter the secondary (cutting edge) in the
“Multi. tool” input field
Enter the identification number of the following
secondary cutting edge in the “M ID” input field;
for the last secondary cutting edge, enter the
identification number of the main cutting edge
Conclude with “OK.”
Watch for the “closed chain” in
Multipoint tools (main tooth—auxiliary
teeth—main tooth).
