Settings File for Profile Shrinkage Compensation
With the Manual and Automatic shrinkage compensation functions it is possible to compensate the shrinkage of profiles in length direction.
When the Plate Shrink.Comp. For Profile setting in System Management > Production > Plate Cutting Data > Extra Length/Shrinkage is set to Disabled (default), the system uses the values set in %ncgnorms%\shrinkage\settings.dat file for compensating profiles. This file defines shrinkage compensation factors for different profile types in different plate thickness ranges. Additionally, the material types of the profiles can be considered as well.
Two factors determine the compensation:
- plate thickness of the plate on which the profile is added
- the profile type
The settings.dat file should have a line for each profile type to be considered in shrinkage compensation. The profile type must be defined first, and then ranges of plate thickness followed by the desired shrinkage compensation factor for that thickness range.
Examples:
HP200X10 0-20 1.001 20-40 1.002
HP160X8 0-5 1.001 5-6 1.003 6-8 1.004 8-10 1.005 10-12 1.006 12-14 1.007 14-100 1.008
Note: The line may not be longer than 160 characters.
If the material type needs to be taken into account when determining the compensation factor, the material type can be added before the profile type. The material type must be connected to the profile type. When the material type is used in the definition, more than one line for each profile type is allowed.
Example:
ALMHP200X10 0-20 1.001 20-40 1.002
Note: If the profile type is not present in the file and the compensation of profiles in length is enabled, an error is shown in the log file when a profile sketch or a profile list is generated. The profile length will not compensated in this case.
