7.1.1 Programming the tool orientation

Five-axis programs are generally generated in

CAD/CAM systems and not typed in on the control.

The following description is therefore intended

mainly for programmers of postprocessors.

There are three ways of programming the orientation

of the tool:

1. Program the movement of the rotary axes. The

change in orientation always takes place in the basic

or machine coordinate system. The orientation axes

are traversed as synchronized axes.

2. Programming in Euler or in RPY angles with A2,

programming the direction vector with A3, B3,

C3. The direction vector points from the tool tip in

the direction of the tool holder.

3. Programming via lead angle LEAD and side

angle TILT (face milling).

In all cases, orientation programming is only

permitted if an orientation transformation is active.

Advantage: These programs can be transferred to

any machine kinematics.
