Comparison of offset and 3D basic rotation

The following example shows how the two functions differ.

Offset

3D basic rotation

Initial state

B_OFFS_01_A01
  • Position display:
  • Actual position
  • B = 0
  • C = 0
  • Preset table:
  • SPB = 0
  • B_OFFS = -30
  • C_OFFS = +0

Initial state

SPB_01_A01
  • Position display:
  • Actual position
  • B = 0
  • C = 0
  • Preset table:
  • SPB = -30
  • B_OFFS = +0
  • C_OFFS = +0

Movement in +Z without tilting

B_OFFS_02_A01

Movement in +Z without tilting

SPB_02_A01

Movement in +Z with tilting

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

B_OFFS_02_A01
  1. The orientation is not correct!

Movement in +Z with tilting

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

SPB_03_A01
  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.
