A ”>>” after the input box means ”fixed-
word list.” Select the tool parameters from
the ”fixed-word list” and use it as input.
Calling the fixed-word list: Position the
cursor on the input box and press the
”>>” soft key.
8.1.5 Explanation of Tool Data
■ Tool ID number: Each tool is assigned a unique ID (with up to 16
letters and numbers). The ID number must not start with with an
underscore.
■ Tool type:
■ First and second numeral: Type of tool
■ Third numeral: Tool position/main machining direction
■ Setting dimensions (xe, ze): Distance from tool reference point to
tool-carrier reference point (Tool-carrier reference point: see machine
manual)
■ Compensation values (DX, DZ, DS) compensate for the wear of
the cutting edge. For recessing and button tools, DS stands for the
compensation value of the third side of the tool (away from the tool
reference point).
■ Cutting length (sl): Length of cutting insert.
■ Check the contour cycles as to whether the tool can perform the
required cutting job.
■ Influences tool selection in TURN PLUS.
■ Is evaluated for simulating the cutting path and depicting the tool.
■ Secondary machining direction (NBR): Defines the directions in
which the tool works in addition to the main direction.
■ The contour cycles check whether the tool is suitable for the
respective machining operation.
■ Influences the tool selection in TURN PLUS.
■ For the secondary machining direction, the AWG uses:
The secondary feed rate (see ” 8.3 Technology Database (Cutting
Values)”)
– a reduced cutting depth (see machining parameter 4 – ”SRF”
■ Direction of rotation defines the direction of spindle rotation for
the tool; defines whether the tool is a driven/non-driven tool.
■ The contour-based cycles check whether the tool is suitable for
the respective machining operation.
■ The direction of rotation influences tool selection in TURN PLUS.
■ It also defines the direction of spindle rotation for AWG.
■ Width (dn): Tool width from tool tip to shank back. The parameter
for width (dn) is evaluated for graphically representing the tool.
■ (Physically) available: Identifies an unavailable tool without deleting
the database entry.
■ Version: ”Left or right tool” – defines the position of the tool
reference point. For neutral version tools, the tool reference point is
located on the left side.
■ Picture number: Display the tool or only the tool tip?
■ 0: Display tool
■ –1: Display only the tool tip
