Siemens SINUMERIK 840DE sl Commissioning Manual page 585

Manually adjustable rotary axes (manual mode) are possible with and without measuring
systems and can be used with "simple machines".
Rotary axes that are positioned by an additional mechanical system, can be declared in the
"Semiautomatic" mode.
Example
In a boring mill, the swivel head is positioned by coupling the spindle. In this case, the rotary
axes of the swivel head must be declared as "Semiautomatic". The appropriate machine-
specific cycles are called in CUST_800.SPF.
Swivel head
● I3 distance from the tool adapter to the pivot point/intersection of the 2nd rotary axis
● I2 distance from the pivot point/intersection of the 2nd rotary axis to the pivot point/
intersection of the 1st rotary axis
● I1 closure of the I1=-(I2+I3) vector chain, if the swivel head cannot be changed
Swivel table
● I2 distance from the machine reference point to the pivot point/intersection of the 1st rotary
axis
● I3 distance from the pivot point/intersection of the 1st rotary axis to the pivot point/
intersection of the 2nd rotary axis (or to the reference point of the tool adapter)
● I4 closure of the I4=-(I2+I3) vector chain, if the swivel table cannot be changed
Swivel head/swivel table (mixed kinematics)
● I2 distance from the tool adapter to the pivot point/intersection of the 1st rotary axis
● I1 closure of the I1=-I2 vector chain, if the swivel head cannot be changed
● I3 distance from the machine reference point to the pivot point/intersection of the 2nd rotary
axis (or to the reference point of the tool adapter)
● I4 closure of the I4=-I3 vector chain, if the swivel table cannot be changed
The offset vectors do not have to point to the pivot point of the rotary axes. The important thing
is that they point to a point on the direction of rotation (intersection).
The sign of the offset vectors (I1 to I4) and the rotary axis vectors (V1, V2) result from the
specifications of the axis directions according to ISO 841-2001 or DIN 66217 (right-hand rule).
