Execution of additional blocks

If additional to the traverse blocks at the block end (N10 – N20) a command without any contour information is programmed (e.g. M-function with MVS_SNS-synchronization), this command can be executed before, during or after the contour curve.

Example: 

N10 X100 G61 M25 
N20 Y100
Execution of additional blocks 1:
Fig. 4.36: Synchronization without contour relevant actions during contouring
Execution of additional blocks 2:
Fig. 4.37: Synchronization without contour relevant actions after contouring

For the execution of this commands there are the following 3 possibilities:

  1. 1Directly after pre-block (N10) and before the first contour polynomic,
  2. Between the first and the second contour polynomic,
  3. Behind the second contour polynomic and before the post-block (N20).
