Tool Offsetting - HEIDENHAIN POSITIP 880 User Manual

Tool Offsetting

The POSITIP 880 can store the dimensional offsets for up to 99 tools.
When you change a workpiece and establish a new datum, all tools are
automatically referenced from the new datum.
Before you can use a tool, you must enter its offset (the cutting edge
position). Tool offsets can be set using the TOOL/SET or NOTE/SET
features or they can be determined using a tool presetter. Refer to the
section on Tool Table for more information on entering tool offsets.
The TOOL/SET and NOTE/SET soft keys are available when in the
ACTUAL VALUE operating mode. The following outlines the
procedures for setting tool offsets using TOOL/SET and NOTE/SET.
Setting tool offsets using TOOL/SET
The TOOL/SET operation can be used to set a tool's offset using a tool
when the diameter of the workpiece is known.
Example: Entering tool data when the workpiece diameter is
known
Touch the known diameter in the X axis.
Select the axis (X) key or press the TOOL SET soft key.
Enter the position of the tool tip, for example,
X=10mm. Press ENT.
Touch the workpiece face with the tool.
Cursor to the Z axis.
Set the position display for the tool tip to zero, Z=0.
Press ENT, then press USE.
POSITIP 880 stores the tool data under the tool number in the tool
table. Set the tool data for all other tools as described here.
