Tools with more than one cutting edge
If you use special tools with more than one cutting edge, different tool
parameters apply (set-up dimensions, cutting radius, etc.). Enter more
than one tool definition to define these tools. If "T" is programmed with
four digits (Tddpp), program a new "dd" ("pp" remains the same) when
another cutting edge of the special tool is used.
Tools in different quadrants
Example: The principal tool carrier of your lathe is in front of the
workpiece (standard quadrant). An additional tool holder is behind the
workpiece.
When MANUALplus is configured, it is defined for each tool holder
whether the X dimensions and the direction of rotation of circular arcs
must be mirrored. In the above-mentioned example the additional tool
holder is assigned the attribute "Mirrored."
If this method is used, all machining operations are programmed as
usual—regardless of which tool holder executes the operation. The
simulation also shows all machining operations in the standard
quadrant.
The tools are also described and dimensioned for the standard
quadrant—even if they are inserted in the additional tool holder.
Mirroring does not become effective until the machining of the
workpiece, i.e. when the additional tool holder is executing the
machining operation.
Feed rate
"F" is the identification letter for feed data. Depending on which mode
of the Feed rate soft key is active, data is entered in:
„ Millimeters per spindle revolution (feed per revolution)
„ Millimeters per minute (feed per minute).
On the screen, you can tell the type of feed rate from the unit of
measure in the input field.
You can change the feed value with the feed compensation
controller (feed override) (range: 0% to 150%).
„ If a driven tool is active, the spindle speed and speed
limitation refer to the tool.
„ Your machine documentation provides information on
whether the driven tool can be operated with feed per
revolution.
