- Tool length offset value and setting in parameter No. 19666
A sum of the tool length offset value (to be set on the offset setting
screen) and the setting in parameter No. 19666 (including the positive
or negative sign) is assumed to be the distance between the tool center
point and controlled point. (The direction is determined by
parameter Nos. 19697 to No.19699.)
As shown in the right side of the figure below, when setting the
distance from the tool center point to tool holder tip point as the tool
length offset value, set the distance from the tool holder tip point to
the controlled point in parameter No. 19666.
As shown in the left side of the figure, when setting the distance from
the tool center point to datum plane as the tool length offset value, set
the distance from the datum plane to controlled point in parameter No.
19666.

Example:
Setting examples 1 and 2 below result in the same operation:
Setting example 1:
(Example of settings on the right side of the above figure)
Tool length offset value = 10.000
Parameter No.19666 = 5.000
Setting example 2:
(Example of settings on the left side of the above figure)
Tool length offset value = −15.000
Parameter No. 19666 = 30.000
