Programming
Velocity smoothing in the NC program is programmed using the #LAH command. This NC command can be used to enable/disable velocity smoothing and to change the parameters when the NC program is active.
Syntax: | |
#LAH [SMOOTH_PATH_VEL =.. PROD_FACT =.. ] | non-modal |
SMOOTH_PATH_VEL=.. | Enable/disable velocity smoothing 0: Velocity smoothing not enabled 1: Velocity smoothing enabled |
PROD_FACT=.. | Productivity factor in % |
Attention
When you enable velocity smoothing and change the productivity factor, both keywords must always be programmed.
If one parameter is missing, the error ID 21104 is output.
Programing Example
Programming example for velocity smoothing
This programming example shows a simple NC program where a linear block sequence is passed through 3 times.
- Pass 1 (S1): without velocity smoothing
- Pass 2 (S2): with velocity smoothing of 90% enabled
- Pass 3 (S3): Velocity smoothing parameters are changed to 50% and then velocity smoothing is disabled.
