Tool offset data for the selected cutting edge of a tool (D No.)
Tool length
You can determine this value using the "Measure tool" function (see
Sec. "Measuring the tool manually"). If the tool is measured externally,
you can enter the value here.
Radius or diameter of the tool
You can also enter the diameter for milling cutters and drills. A
machine data code is used to switch from radius to diameter
specification.
Angle of tool tip on a drill.
If you want to insert a drill down to the shank, and not just to the tool
tip, the control also takes the angle of the drill tip into account.
The "H" column is displayed only if ISO dialects are set up. Every H
number of an ISO dialect program must be assigned to a tool offset
data record.
Number of teeth for a milling cutter
Thread lead of a tap in mm/rev or turns/" if the inch system is set up
on the machine.
Spindle rotation
Coolant supply 1 and 2 can be activated/deactivated (e.g. internal and
external cooling)
Other tool-specific functions such as additional coolant supply,
monitoring functions for speed, tool breakage, etc.
Please refer to the machine manufacturer's instructions.
The "Details" softkey displays the additional parameters "Rounding
radius" or "Angle" for 3D tapered milling tools.
For the facing tool, an additional outside radius and tool angle, and for
angle head cutter, additional lengths and wear lengths are displayed
under "Details.
