- Offset vector
The offset vector is the two dimensional vector that is equal to the
cutter compensation value assigned by D code. It is calculated inside
the control unit, and its direction is up-dated in accordance with the
progress of the tool in each block.
The offset vector is deleted by reset.
- Specifying a cutter compensation value
Specify a cutter compensation value with a number assigned to it. The
number consists of 1 to 3 digits after address D (D code). The D code is
valid until another D code is specified. The D code is used to specify
the tool offset value as well as the cutter compensation value.
- Plane selection and vector
Offset calculation is carried out in the plane determined by G17, G18
and G19, (G codes for plane selection). This plane is called the offset
plane.
Compensation is not executed for the coordinate of a position which is
not in the specified plane. The programmed values are used as they are
In simultaneous 3 axes control, the tool path projected on the offset
plane is compensated.
The offset plane is changed during the offset cancel mode. If it is
performed during the offset mode, a alarm (PS0271) is displayed and
the machine is stopped.
