2.7.4 Measure tool in JOG

When executing a program, the various tool geometries must be taken into account. These are
stored as tool compensation data in the tool list. When the tool is called, the control considers the
tool compensation data.
You can determine the tool compensation data (i.e. the length and radius or diameter) either via
special tool pre-setting devices or with the aid of the measuring functions on the machine.

TTP = Tool Tip Point
CAM systems define the position of the reference point differently depending on the tool
shape. Generally it is assumed that the output tool path refers to the tip of the milling
cutter (TTP). If the CAM system specifies a different reference point, then this difference
must be taken into account when specifying the tool length. You can perform this, for
example, via the TOFFL command in the NC program.

The CAM system usually takes into account
the tool diameter when the geometry program
is being created. The calculated tool path
usually refers to the miller center point and the
tool tip (TTP) (center point path).

This means that to measure the length of the

(TTP) as the CAM system. For the purpose of
determining the tool length, always remember

programmer used to measure L1. The TTP is
on the tool tip. The TCP (Tool Center Point)
can be further up in the milling tool - e.g. for
radius end mills at the center of the radius.
The tool magazine is equipped as usual. The

The typical milling tools are available for
selection in the tool catalog. You only have to
insert these and enter the necessary
compensation data.
