If the tool moves outside the blank like in the return motion to the turret
position, the system examines the interference up to the position of the
maximum blank size before moving the tool. Then, the movement of the
turret position is output.
If the tool directly moves to the turret position from point (A), the tool
interferes with the convexed part.
In such a case, the tool moves to the turret position after it has retreated
up to point (B) at the blank end.
Whether the “return relief” movement is done on the simultaneous two
axes or one axis only is determined by system parameters No.0107 to
It should be carefully noted that the tool referred to here is defined as nose
R (nose circle) only, and it does not include any other tools.
In other words, the system checks the tool nose angle, but it does not check
such an interference as the blank touches a shank or other part other than
specified above in the following figure, for example.
Such a conditions as
illustrated here is not

and nose R are set

In case of threading tool the system checks the interference
by the nose R specified by the virtual tool position.
If an undesirable tool path is output, specify the opposite
nose R by the virtual tool position.
