distances from the standard point to the tool nose radius center than from the standard point to the
imaginary tool nose, and so set the tool offset value by measuring distance from the standard point to
the imaginary tool nose(tool nose direction of T3).

4.1.4 G40/G41/G42 command function
Taking the previous and the current position increment as the programmed path can cancel the
tool compensation mode, and its direction is the compensation direction of the previous. When the
system specifies
（
I, J
）
,
（
I, K
）
or
（
J, K
）
, the vector defined by it can replace the current position
increment to execute the count.
Command format:
X Z T ;
In machining workpiece, the tool offset cannot easily compensate the precise workpiece because
of the tool nose circle degree but the tool nose radius compensation function can automatically
compensate the error.
