6.5 Tilting and swivel axes
6.5.1 Determining the mechanical offset
July 2013
Swivel heads and tilting tables are often used on milling machines for 5-axis
machining and to machine workpieces from several sides.
The NC programs are written with a CAD system or directly at the iTNC using
the Tilt working plane (Plane, TCPM) function. The user programs the part
program in the X/Y plane and the iTNC interpolates the proper axes. All path
functions, cycles, "datum setting" and "probing" can be applied in the
transformed working plane.
As an example, we will show how to determine the mechanical offset of a 45°
double swivel head and of a forked swivel head.
Note
The 3-D ROT function must be inactive during the entire measuring
process.
