Comparison of offset and 3D basic rotation

The following example shows how the two functions differ.

Offset

3D basic rotation

Initial state

Position display:

  • Actual position
  • B = 0
  • C = 0

Preset table:

  • SPB = 0
  • B_OFFS = -30
  • C_OFFS = +0

Initial state

Position display:

  • Actual position
  • B = 0
  • C = 0

Preset table:

  • SPB = -30
  • B_OFFS = +0
  • C_OFFS = +0

Movement in +Z without tilting

Movement in +Z without tilting

Movement in +Z with tilting

PLANE SPATIAL with SPA+0 SPB+0 SPC+0

  1. The orientation is not correct!

Movement in +Z with tilting

PLANE SPATIAL with SPA+0 SPB+0 SPC+0

  1. The orientation is correct!
  2. The next machining step will be correct.
 
Tip

HEIDENHAIN recommends using 3D basic rotation because of its greater flexibility.
